4 HVAC system piping are usually designed based on velocity limits to avoid pipe erosion, cavita on and noise issues. As seen below, the table has been developed using the MRV (Maximum Recommended Velocity) limits of 7 /sec to allow piping to be easily and quickly sized. The above limits certainly do vary as a func on of es mated opera ng hours, system opera ons, pumping system and different applica ons.

33 2519 Series Y-Ball Automatic Flow Control Valves INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS GENERAL INFORMATION 1. Clean the lines of all foreign material, (welding slag, pipe scale, dirt, thread chips etc.). Upstream installation of a strainer may be necessary in dirty systems. 2. Air should be eliminated from the system prior to startup to assure quiet operation and freedom from water hammer. 3. Hays Automatic Flow Control Valves may be installed in the pipe horizontally, vertically or any angle in between. Straight sections of pipe upstream or downstream of the Hays valve are unnecessary for proper operation. Standard reducing bushings or flanges may be directly connected to the Hays valve if required. 4. All Hays Automatic Flow Control Valves are marked with direction of flow and rate of flow. THE FLOW ARROW MUST POINT IN THE DIRECTION OF FLOW FOR PROPER OPERATION. 5. Hays Flow Control Valves are factory assembled, and individually calibrated. The valves are warranted to be accurate within +/-10% of rated flow when properly installed. 6. Hays Automatic Flow Control Valves may be modified by using a Hays Service Kit. Contact Factory for part numbers, instructions and other details. OPERATION 1. For optimum operation, air entrainment in the system must be eliminated. The flow control valve must remain filled with fluid. The system must be clean and free of foreign materials. 2. The Hays Y-Ball Series Valves must only be used with fluids that are compatible with, Brass, and EPDM materials. The temperature during operation must be limited to the range of 32 F to 225 F. 3. The use of fluids having a specific gravity different from that of water will require adjustment. Valves specified for fluids other than water will be so marked and the factory calibration will take the specific fluid s properties into consideration. Operation at a temperature other than the rated temperature may require a correction. INSTALLATION 1. Threaded valves are provided with ½ or ¾ inch Dryseal NPT threads in accordance with ANSI STD B and are intended for use in Building Services Piping meeting the requirements of ASME B Apply thread sealant to male pipe threads, starting with the second or third thread from the end, and torque the connection to 75 foot pounds per inch of pipe size minimum. Example: (½, 0.5 X 75 = 38 ft lb. Min,) (¾, 0.75 X 75= 62.5 ft lb Min.) ABV-IOM MAR 2013 Page 1 of 2

34 INSTALLATION CONTINUED 2. Sweat fitting valves have their end connections formed to ANSI STD B16.22 requirements and are intended for use in Building Services Piping meeting the requirements of ASME B The Temperature/Pressure rating of the Solder Joint is dependent upon the type of solder used. ANSI STD B16.22 Pressure Ratings should be reviewed prior to selecting a solder and sweating. Union end pieces on the valves should be removed for sweating (ball valve end is not removable). The union o ring must be removed and stored during the operation. The outside of the tubing, and the inside of the fitting are to be mechanically cleaned and then lightly coated with solder flux. The tube is then inserted one diameter into the fitting, and the CENTRAL PORTION OF THE VALVE BODY WRAPPED WITH A WET RAG. Heat may be applied, either to the tubing or to the end of the fitting so as to achieve solder flow. When the parts have achieved the necessary temperature, solder is to be added to the joint and the joint allowed to cool. The heat is to be applied for the shortest time possible.

The valves are warranted to be accurate within 10% of rated flow when properly installed. OPERATION 1. For optimum operation, air entrainment in the system must be eliminated. The flow control valve must remain filled with fluid. The system must be clean and free of foreign materials. 2. The Hays Mesurflo Valve must only be used with fluids that are compatible with, Iron, Brass, and EPDM materials. The temperature during operation must be limited to the range of 32 F to 225 F. 3. The use of fluids having a specific gravity different from that of water will require adjustment. Valves specified for fluids other than water will be so marked and the factory calibration will take the specific fluids properties into consideration. Operation at a temperature other than the rated temperature may require a correction. INSTALLATION 1. Flanged valves are intended for use in Building Services Piping meeting the requirements of ASME B 31.9 and are supplied with ANSI B16.5, 2003, 150 lb. Raised face steel flanges. These flanges are to be connected into the piping system utilizing new ASTM A194, GR 2H, nuts, new ASTM A193 GR B7 bolts, size 3/4 inch, for 6 & 8 inch, size 7/8 inch for 10 & 12 inch and two hardened steel washers under each nut. Appropriate gasket material must be used when installing flange mounted flow control valves. The thinnest practical gasket should be used whenever possible so as to optimize the joint performance. 2. A non-metallic based lubricant such as oil or graphite is to be applied to the nuts and bolts, and the assembly uniformly torqued to, 200 foot lbs for 6 & 8 flanges, 320 foot lbs for 10 & 12 flanges. Bolts should be torqued in at least three even steps using a star or crossing pattern until the final torque is reached. 3. Welded valves are to have their plastic inlet and outlet covers removed, and the valve placed in the pipe line so as to minimize the entrance of weld slag into the plumbing. Welding is to be performed in ABV-IOM MAR Page 1 of ABV

66 accordance with the applicable requirements required for the system. 4. Grooved End valves are to have the grooves checked for indentations, projections or other imperfections which could prevent proper sealing. The gasket is to be checked, and lubricated with a thin coating of the proper lubricant to the outside and sealing surfaces. Keep the lubricated surfaces clean. Slip the gasket over the two ends of the valve, making sure they do not over hang. Place the valve in position with one of the connecting pipes. Pull the gasket in a centered position between the groove in the pipe and the groove in the valve. The gasket should not protrude into either groove. Remove one nut and bolt from the coupling, and loosen the other. Place one half of the coupling over the gasket making sure the coupling keys fit into the housing grooves. Swing the other coupling half over the gasket and into the grooves on both housings, making sure the tongue and recess of each coupling is properly mated. Re-insert the bolt and run-up both nuts finger tight. Securely tighten the nuts alternately and equally until completely tightened, keeping the gaps at the bolt pads evenly spaced. MAINTENANCE General maintenance is not required for Hays Flow Control Valves, however if the system experiences large amounts of pipe scale due to poor water conditions, as sometimes is found in older or retrofit systems, some maintenance may be required. Provision should be made to keep the system clean. Proper water treatment is also recommended. LIMITED WARRANTY See Hays Fluid Controls current Terms & Conditions for warranty information.

75 MESURFLO AUTOMATIC BALANCING VALVE TECHNICAL DATA How the Mesurflo Controls Flow Figure 1 0 PSID Figure PSID Figure 3 Reverse Flow For a pressure differential range of 2 to 80 psid, as the pressure drop increases, the rubber diaphragm will flex into the contoured orifice plate to decrease flow path. Both the rubber diaphragm and the contoured orifice plate are rigidly controlled to provide a constant flow rate over the pressure differential range. The flexing of the rubber diaphragm against the fixed orifice plate makes the Mesurflo difficult to clog and resistant to cavitation damage. The flexing action actually chews up debris preventing clogging. Outside of the pressure drop window, the controller performs similar to a fixed orifice. NOTE TO PIPING DEISGNERS: The Hays Mesurflo is a constant flow rate device. Since it is a variable orifice that changes to govern the flow, it can not be described with the Cv or a pressure drop at a given flow for piping system design purposes. Conversely, the designer may assume a constant flow rate over the differential pressure. HAYS, HVAC, Hydronic System Automatic Balancing Valves are protected by U.S. Patent 6,311,712.

77 Glycol 1. Subject and Scope Use of Mesurflo flow controller with high concentrations of anti-freeze water solutions. Is a correction factor necessary for proper application? 2. Applicability All mixtures wherein the density of the final solution will deviate significantly from that of pure water are covered providing the following criteria hold true. This bulletin will cover fluids with only small changes in viscosity from water. For fluids whose viscosity differs markedly from that of pure water contact Hays Customer Service. Fluids that are compatible with the materials used in a Mesurflo valve. The fluid used must be compatible with copper, brass and EPDM materials. The fluid is Newtonian (shear stress is proportional to the rate of strain). 3. Background The Mesurflo is an accurate and economical solution to automatic flow control. Constant flow rates may be held over a wide variety of differential pressures. Unless otherwise requested the specifications for Mesurflo valves are referenced to flow rate in water. The design of the Mesurflo valve provides a constant rate of mass flow over a wide range of pressures and temperatures. Most HVAC systems do not utilize 100% concentration of water in their systems due to freezing issues. Changes in fluid transport properties will result in small changes in volumetric flow rate when using Mesurflo devices. The cold temperature design point for most systems is a result of the environment in which they are installed. Concentrations of anti-freeze additives such as Ethylene-Glycol are usually below 50%. As a result the majority of HVAC systems require no flow rate correction when using a Mesurflo R02 Glycol Bulletin

78 For systems designed to operate in extreme cold climates greater percentages of anti-freeze additives are required. For example in a climate such as Alaska percentages of Ethylene-Glycol may be required to be significantly higher. A correction to account for the variation in fluid properties may be used to ensure the design flow rates in these situations. 4. Details The Mesurflo valve is a constant mass flow device. To determine the volumetric flow rate of a fluid whose density is different from that of water it is only necessary to divide the flow rate in water by the ratio in densities of that fluid and water. The equation below expresses this relationship in mathematical form: w V V w * Where V is the volumetric flow rating of the Mesurflo w f w is the density of water at the reference temperature is the density of the alternate fluid at the f reference temperature V is the resulting volumetric flow of the alternate fluid For example, to obtain the correct volumetric flow rate of a mixture of an Ethylene Glycol-Water of 70%/30% it would be necessary to determine the density of the Ethylene Glycol -Water mixture and water alone at that temperature. For our example we will use a density of 69.1 lb/cu ft for the Ethylene Glycol-Water mixture. The reference density of water at this temperature is lb/cu ft. The resulting calculation to determine the flow rate through a Mesurflo rated at 3 gpm in water is: V * w 3* 2.7 gpm (of 70% Ethylene glycol / 30% Water) f 69.1 V w 5.

81 Evaporator Accuracy Subject and Scope In the use of Mesurflo flow controllers in water source heat pumps, what level of accuracy is required? 1. Applicability This Technical Tip applies to all water source heat pumps and air conditioners. 2. Summary The impact of flow control device accuracy on heat exchanger performance is non-linear. The variation in heat transfer from a heat exchanger resulting from variation in flow rate is less than the percentage change in the flow rate. A ±10% flow control will provide better than ±5% on heat transfer variation. The following discussion will provide analysis and data to prove this. 3. Background The water flow in a water source heat pump (or air conditioner) is used as either source or sink for heat. Automatic flow control devices are intended to be used to regulate the flow of water to the heat pump ensuring that high pressures do not cause this excessive flow and result in either catastrophic failure (erosion) or starving of other heat pumps in the distribution system. The accuracy of the flow rate required is a frequent topic of discussion. The change in heat transfer due to variations in flow of a condenser or evaporator is provided below. This curve demonstrates the physical limitations in heat exchanger design. As Percent Design Heat Transfer 100% 80% 60% 40% 20% 0% 0% 20% 40% 60% 80% 100% Percentage Design Coolant Flow R01 Evaporator Accuracy

82 flow is increased the heat transfer continues to increase, however, the rate slows down. This is referred to as diminishing returns. This curve can be derived from the effectiveness-number of transfer units (NTU) equations. The relationship used to create this graph is valid for all types of heat exchangers that operate with a condensing or evaporating fluid. Inspection of this curve indicates that at the design point, 100% flow, of the heat exchanger a change in coolant flow rate will result in a much smaller change in heat transfer. From this it is also obvious that the impact of a change in flow is dependent upon the choice of design point. The effectiveness NTU relations allow us to determine the accuracy of a flow control device necessary to achieve a specific range of heat transfer control. The technique used to establish the accuracy of heat transfer rate as a function of flow is described in the next section. The graph below presents the heat transfer variation due to a ±10% variation in flow % Heat Transfer Accuracy at ±10% Flow 10.0% 1.0% 0.1% NTU 4. Details The heat capacity, C, of a fluid is the product of the mass flow rate and the mass specific heat capacity of the fluid. For fluids that undergo a change of state there is no change in temperature with absorption of heat therefore the heat capacity of the side changing state is taken to be infinite R01 Evaporator Accuracy

83 The minimum fluid, C MIN, is the fluid with the smallest value of heat capacity. For this reason the minimum fluid in a condensing or evaporating heat exchanger (as in a water source heat pump) is always the water. The maximum possible heat transfer, Q MP, is the heat capacity of the minimum fluid times the result of inlet temperature of the hot fluid minus the inlet temperature of the cold fluid, Q MP =C MIN *(T WATER,IN -T REFRIGERANT,IN ). The actual heat transfer, Q ACT, is the heat that will be transferred by the heat exchanger under the conditions specified. It is also equal to the heat capacity times the temperature difference of the water, Q ACT =C MIN * T WATER. Effectiveness ( ) is defined as the ratio of the actual heat transfer to the maximum possible heat transfer. The Number of Transfer Units, NTU, is defined as the overall heat transfer coefficient, UA, divided by the minimum heat capacity, C MIN. The definition for effectiveness may be expressed as follows: QACT CMIN * ΔTWATER CMIN * ΔTWATER ε = = = QMP CMIN *( TWATER, IN TREFRIGERANT, IN ) CMIN * ΔTMP The actual heat transfer can be determined from: UA QACT = ε * QMP = ε * CMIN * ΔTMP = ε * * ΔTMP NTU The effectiveness for a heat exchanger with an evaporating or condensing fluid may be expressed as: ε = 1 e NTU Substituting this expression to the one above: NTU UA QACT = ( 1 e )* * ΔTMP NTU This expression provides a means of determining the heat transfer of a heat exchanger as a function of NTU and two constants, UA and T MP. After the heat transfer is calculated the following expression can be used to determine how large a change in NTU will make a change of ±5% in heat transfer: ΔTWATER NTU ' = log 1 TWATER, IN TREFRIGERANT, IN Since we are holding UA constant the ratio of C MIN to C MIN is as follows: C' MIN NTU = CMIN NTU ' For fluids such as water the density and specific heat have such a minimal change the ratio of C MIN to C MIN is the same as the volumetric flow ratio R01 Evaporator Accuracy

84 The graph below relates the required accuracy in flow to maintain heat transfer within a ±5% range of nominal. Below an NTU of 1.25 a ±10% change in water flow will meet the requirement.

The ideal heat exchanger would bring the temperatures of the water to the temperature of the refrigerant, or 100% effectiveness. The difference that exists in real heat exchangers between the outlet water temperature and the refrigerant temperature is called the approach temperature. As the temperature of the water approaches the refrigerant temperature the size of the heat exchanger approaches infinity. In the plot below lines of constant T WATER are plotted on the range of refrigerant temperature and NTU.

89 Clogging of Automatic Flow Controllers Subject and Scope All mechanical systems are subject to contamination. HVAC systems frequently contain material too small to be separated by strainers that can cause valves to fail. The Hays Mesurflo is the exception to this rule due to its unique design containing no sliding parts. 1. Applicability The testing used to create this Technical Tip was done specifically to evaluate the capability of the subject valves to operate in a system with a strainer present. Larger particulates that would reach the valve in a system without a strainer were not evaluated. Even when large particulates are plentiful they tend not to circulate as far or as quickly through HVAC systems. The drag force that pushes particulates around a system is a function of the Reynolds Number based on the hydraulic diameter of the particulate. Stoke s Law predicts that the Coefficient of Drag will increase inversely proportional to the Reynolds Numbers when the Reynolds number is 1 or below. This agrees well with experimental data. Drag on a Sphere The higher drag force of the smaller particles allows them to be circulated through the system at velocities where larger particulates will fall out. Details 100 Coefficient of Drag A test apparatus was 1 developed to introduce material (iron filings, and iron oxides) 0.1 into a flow stream at a controllable rate. The system was designed as an open loop 0.01 system with particulates caught Reynolds Number Experimental Data Stokes Law in a filter at the outlet. The rate of addition of particulates was controlled to either 0.8 or 3.6 oz/hr in a water flow of 1 gpm. The valve under test was connected to the outlet of the system and valve inlet pressure was varied from 5 to 30 psid. Water flow was measured and failure was taken to occur when the valve no longer controlled flow to a constant rate for more than 2 cycles ,000 10, ,000 1,000,000 10,000,000 The predominant mode of failure for all of the metal spring valves was jamming of sliding members. Quantitatively, as few as one foreign particle can jam the sliding member due to the small clearances required to operate these valves at high pressures. Every one of the spring loaded devices jammed. They jammed during the first cycles of the tests, the amounts of the iron fillings that jammed those devices were below the measurement threshold. The most predominant mode of failure was the foreign object (iron particulates in our test) jammed in the gap between the sliding and fixed components as shown to the left. When the tests were run for longer periods (in spite of the valves not functioning) additional material would accumulate in the narrow portions of the opening on the R01- Clogging of Automatic Flow Control

90 flow control. Since the openings are small and do not open up at lower pressures the particulates would jam in the opening, further restricting flow to relatively low values. Mesurflo technology does very well with small particulates. The iron filings accumulate in the low velocity area around the base of the Mesurflo. As long as the opening between the orifice and diaphragm is large enough these particles pass through during the low pressure portion of the test, freeing the valve from contamination. A picture of the Mesurflo after the test at 0.8 oz/hr is provided to the left. The Mesurflo was still controlling flow! 3.

91 Noise Characteristics of Automatic Flow Controllers 1. Subject and Scope Valve noise is becoming an increasingly important issue as HVAC systems become more efficient and take up an ever smaller portion of a building envelope. The Hays Gold Standard valve, Mesurflo, is the industry leader in low noise technology. Valves with superior noise characteristics are required whenever a valve is in the occupied space of a building. This tip will present data on the audible noise. 2. Applicability When applying this data the valve should be considered as the speaker and the building occupant the receiver in a speakerpath-receiver network. A low noise valve is a requirement when a direct path (no sound insulation between the valve and occupant) exists such as in an HVAC terminal unit inside an office building. It is necessary to provide an almost air-tight seal to prevent noise propagation out of an enclosure. 3. Details Hays noise test specification utilizes the ANSI S test method. This test method is widely accepted and used in several ARI standards for rating sound from HVAC equipment¹. Careful attention was paid to the test set up to minimize noise generated by other sources such as fluid flow upstream and downstream of the valve. At each test condition a base line measurement was made with the valve replaced by a short straight section of pipe. This value will represent the lowest possible level of noise achievable at that condition. The test was run at a very low pipe water velocity to minimize the noise generated by other components of the test system. A pipe flow velocity of approximately 1.25ft/s was used. Testing was conducted at an inlet Reynolds number of approximately 5,000. All valves tested were combination flow control and isolation valves with the ball valve for isolation in the full open position. Each valve was tested at a variety of pressure drops from below typical operational levels to above typical operational levels, or, 2 to 48 psi. Flow through the valve was regulated by the flow control valve itself (except in the case of straight pipe where regulation was done outside the test chamber). Overall A-weighted Sound Pressure Levels at Various Water Pressure Differences Results in dba Water Pressure (psi) Mesurflo Pipe Competitor A Competitor B Competitor C Mean The Mesurflo is the clear leader in the overall A-weighted sound pressure data provided above. A-weighted sound data alone is not sufficient to judge the noise quality of a product.

Fortunately the Mesurflo pro vides a clear benefit at almost every frequency. As a means of understanding the noise performance 20 dba has been likened to someone sitting in the corner of your office whispering and 30 dba is the level of a whisper of someone standing next to you. 4.

93 Application Of Manual Valves Theory All manual balance valves on the market today have two functions, flow regulation by a valve or restrictor and flow measurement. The flow measurement function is used to adjust the position of the valve portion to provide the required flow at a given pressure. Many of the manual balance valves on the market today consist of a valve with an indicator showing position. This position is then compared to a chart to determine a value for the flow coefficient (CV) and the flow is determined based on this value. These valves do provide an ability to balance a system. They suffer from difficulty in use and higher than necessary system pressure drops. The Hays Manual Balance valve simplifies the user s process by providing only a constant value for the CV and due to its design minimizes the pressure drop penalty on the system. The Hays Manual Balance valve is a Venturi style device. The pressure measurements across the Venturi do not represent the normal pressures measured in the system. The pressures measured across the Venturi are actually higher than the drop in pressure across the entire device. Since the power consumed in pumping is proportional to system pressure drop a Venturi style meter can help to reduce system operating costs. The basis for the design of a venture style meter is the drop in pressure that occurs when a fluid is accelerated. Mathematically the energy equation, sometimes referred to as Bernoulli s equation, expresses the relation between velocity and pressure as follows (including only the applicable terms): 1 P 1 k + V12 = 2 + V22 + L1 2 V22 ρ 2 ρ 2 2 P1 Where: P1 is the pressure at station 1 P2 is the pressure at station 2 ρ is the density of the fluid V1 is the velocity at station 1 V2 is the velocity at station 2 KL1-2 is the loss factor between station 1 and 2 (negligible for 1 to 2) The cross section of a typical Venturi is shown below: Applying the energy equation to this Venturi will give a great deal of insight. At the entrance, station 1 above, the fluid enters at a low velocity and high pressure. The upstream tap measures the fluid pressure at this location. The cross section is reduced to the minimum at section 2. Since there is less area for the flow the velocity of the flow at station 2 must be higher than at station 1. When this happens in order for the energy at station 2 to be the same as at station 1 the pressure must drop. The low pressure tap on a Venturi is placed at station 2. This lowering of the pressure provides a large pressure reading that can be converted to a flow rate. After the fluid passes through station 2 the cross section of the fluid passage is gradually increased such that no separation of the flow from the sides of the passage will occur. This condition is held as long as possible. Station 3 represents the full diameter of the pipe. The energy equation may also be written between stations 2 and 3 as follows: R01 App. of Manual Valves

94 1 P 1 k + V22 = 3 + V32 + L 2 3 V32 ρ 2 ρ 2 2 P2 This time the fluid will start out in station 2 with a low pressure and high velocity. As the cross section opens up the velocity is reduced. As the velocity goes down the pressure increases to maintain a constant level of energy. The increase in pressure is referred to as pressure recovery. Pressure recovery only occurs when the angle of the expansion between stations 2 and 3 is 15 or less. For angle greater than 15 the loss factor, KL2-3, is proportional to the diameter ratio raised to the fourth power. It is a result of the existence of an expansion section that gives the Venturi a significantly lower impact on system pressure drop compared to competitive meters. An examination of most competitive meters will show that the end of the small cross section expands directly into a larger area imparting a major loss to the fluid stream. Application Simplified versions of the equations in the theory section above are used for practical applications of the Venturi. The CV equation relates the flow through a device to the pressure drop. The equation is expressed as follows: Q = CV ΔP Where: ΔP is the pressure difference measured in psi Q is the flow rate of fluid in gpm CV is the flow coefficient of the valve Two values for CV are available for the Venturi. The Venturi CV (CV,Venturi or just CV) relates the flow through the valve to the pressure difference measured across the valve ports. This CV is used in the field balancing a distribution to calculate flow. The recovered CV (CV,Recovered) is used to determine the impact on system pressure caused by having the Venturi in the line. There are no pressure ports at which this pressure can be measured except in a test lab. This value is used by an engineer to determine the pressure drop in a flow distribution system. For the best accuracy it is recommended that the installation of a clean, smooth straight section of pipe upstream of the valve ten times the internal diameter and downstream for five internal diameters of the pipe be made. The Venturi will retain accuracy without the straight inlet and outlet sections provided that a smooth continuous flow of fluid is upstream of the valve. Use with fluids other than water or differing temperatures The Venturi may be used with fluids other than water at temperatures between 33 F and 225 F. Fluids must be compatible with brass and EPDM to not damage the Venturi. To determine the flow of fluids other than water use this modified version of the CV equation: Q = CV ΔP sg R01 App. of Manual Valves

95 Where: ΔP is the pressure difference measured in psi Q is the flow rate of fluid in gpm CV is the flow coefficient of the valve sg is the specific gravity of the fluid used at the condition during measurement For example a Venturi (CV=0.56) used with a 30% Propylene Glycol and Water mixture (sg=1.048) at 70 F and a 0.95 psi pressure drop would have a flow rate as follows: Q = CV ΔP 0.95 (psi) = 0.56 * = (gpm) sg The Reynolds number of the Propylene Glycol mixture at is 1,732, within the range of usefulness of the venture as indicated by the chart. Therefore, this application will retain the specified accuracy. Alternate forms of the CV equation A careful examination of the flow curves provided for the Mesurmeter will indicate that the lines representing flow are not quite parallel. The equations presented in this Technical Tip represent an industry norm for HVAC applications. Much more involved correlations for the flow of fluid through venturi s nozzles and orifii are used in laboratories where time is significantly less important than accuracy. An intermediate equation that offers a slight improvement in accuracy without too much additional complication has been used to develop these charts. That equation is: ΔP Q = Z sg Where: x ΔP is the pressure difference measured in psi Q is the flow rate of fluid in gpm Z is the flow constant of the valve x is the flow exponent of the valve sg is the specific gravity of the fluid used The flow constants and exponents for the Venturi series are provided in the chart at the end of this Technical Tip. Range of applicability of CV data provided The Venturi has been tested over a wide range of conditions. It is recommended that extrapolation to flow regimes in which the Venturi has not been tested be avoided R01 App. of Manual Valves

Modulating Flow Control with Mesurflo Excellent synergies occur when using a Mesurflo valve with a modulating temperature control valve.

Since the Mesurflo valve will limit the flow rate of fluid independent of pressure the usual way of approaching the combination of two valves using CV values does not work.

A look at how the Mesurflo and a modulating control valve each work from the viewpoint of flow will lead into a clear understanding of how the two will behave together.

99 Modulating Flow Control with Mesurflo Excellent synergies occur when using a Mesurflo valve with a modulating temperature control valve. Both valves serve their design function and do not interfere with the function of each other. Since the Mesurflo valve will limit the flow rate of fluid independent of pressure the usual way of approaching the combination of two valves using CV values does not work. Instead the result must be evaluated in terms of flow directly. A look at how the Mesurflo and a modulating control valve each work from the viewpoint of flow will lead into a clear understanding of how the two will behave together. The Mesurflo flow control device is designed to limit flow through the valve to the rated amount on the valve. The Mesurflo operates by the deflection of a diaphragm on to an orifice plate. As flow increases through the flow control the pressure across the Low Pressure Intermediate Pressure High Pressure Figure A: Mesurflo Deflection with Pressure diaphragm increases. This pressure deflects the diaphragm such that the open area between the diaphragm and the orifice plate decreases as shown in Figure A. The orifice plate is carefully designed such that the flow rate through the device is maintained constant from 2 to 80 psi differential across the Mesurflo. Below 2 psi (minimum operating pressure for most Mesurflo devices) the Mesurflo will behave very similar to a fixed orifice (constant CV). In terms of flow the Mesurflo will produce a restriction proportional to flow rate squared until almost the rated flow. As the flow approaches the rated flow the restriction then becomes independent of flow such that the flow through the Mesurflo is held constant, this is shown in Figure B R01

The performance of a typical Equal Percentage valve for a single pressure across the valve is shown in Figure C. Figure D shows the effect of varying pressures on the flow rate through the valve. Note that at all points above the design pressure the flow can exceed the design flow rate.

102 The Mesurflo prevents the system from experiencing excessive flow. This saves energy by lowering total system flow in conditions where higher than normal pressures occur. This also protects equipment from the detrimental effects of flow induced erosion. Since Mesurflo acts very much like a fixed orifice at flow rates below the design point there is no interaction of the Mesurflo with the Control valve for authority. Due to the diminishing returns of heat exchangers, see Figure F, the impact on the control system of limiting flow to the rated maximum is minimal.

The temperature feedback system will correct for changes in flow due to pressure changes in the system. Below the design point any change in flow will result in a change in temperature off the coil. The controller will modify the position of the valve to provide the correct temperature. This makes the Pressure Independent aspect of a PICCV superfluous below the design point.

At the design point the change in temperature is not sufficient to provide control. For example a dead band of ±2ºF (fairly normal) will result in no position correction until 150% of design flow. Without flow control, this provides a potential waste of 50% of flow, increasing both the pressure drop of the distribution system (further exacerbating imbalance) and the flow required. Mesurflo in line with each control valve will prevent the flow from increasing above the design point, correcting the only limitation found in the use of modulating valves with air off control R01

105 Mesurflo Modulating Control Valve vs. Competitive Valves The Mesurflo Modulating Control Valve is latest addition to our lineup of Mesurflo Automatic balancing valves. Designed with performance and simplicity in mind, the Mesurflo Modulating Control Valve provides accurate modulating flow control and reliable operation in a smaller package and lower initial cost. The Mesurflo Modulating Control Valve combines our patented Mesurflo technology and a characterized control valve to deliver 0-100% flow. In a wide open control valve condition, the Mesurflo has the authority and works as a regular Mesurflo Automatic balancing valve which is selected at the rated terminal unit flow. The flow is constant across the entire pressure differential range 2-80 psi. As the control signal from the thermostat changes, the characterized control valve portion gains authority and controls the flow. The characterized control valve in combination with the specially designed actuator controls the flow even as the pressure in the system changes. The equal percentage characteristic of the control valve guarantees a linear output from the terminal device.

106 MESURFLO MODULATING CONTROL VALVE VERSUS COMPETITIVE VALVES A commonly adopted technology by our competitors is to use a pressure regulator in series with a characterized control valve. In the market these valves are known as the PICC valves. This is one way to control and modulate the flow but we believe that the Mesurflo Modulating Control Valve through its exquisitely simple design provides the same performance with reduced complexity. To understand the operation of PI valve and the Mesurflo Modulating Control Valve, consider the side by side comparison of both valves. As inlet pressure changes, the pressure regulator reacts to the forces exerted by the intermediate pressure, discharge pressure and the spring to maintain a constant flow. In a modulating condition, as the ball valve closes in response to reduced flow requirements the intermediate pressure and discharge pressure change moving the regulator and adjusting the flow rate. The flow is maintained by moving three elements internal to the valve spring, a thin diaphragm and a stem running through the center of the regulator. The Mesurflo technology relies on a patented diaphragm and orifice assembly to control flow through the valve. In modulating condition, the valve relies on the specially designed ball valve and characterized disc combination to provide the required flow rate. All the movement is external to valve. The flow is maintained by moving only one element ball valve. The actuator utilizes sophisticated algorithms to precisely position the valve without over-reacting or being sluggish R1

107 MESURFLO AUTOMATIC FLOW CONTROLS PROVIDE ENERGY SAVINGS FOR ALAMO HEIGHTS INDEPENDENT SCHOOL DISTRICT Preface: Alamo Heights Independent School District determined it necessary to re-evaluate their energy use and find ways of cutting cost while improving the efficiency of their heating and cooling system. Syntergy LLC, offered AHISD cost saving ideas using Hays Fluid Controls Mesurflo Automatic Balancing Valves to control the water flow for their heating and cooling system. Syntergy was very confident in the operating efficiency of Hays balancing valves. Alamo Heights High School San Antonio, Texas Situation: Alamo Heights High School was built in AHISD was having trouble maintaining comfortable temperature control in selected areas of their high school that relied on chilled water to provide cooling. After verifying capacity at the central plant, Syntergy LLC, determined that the age, combined with numerous expansions, left the District s chilled water distribution system unbalanced and inefficient. Solution: Syntergy, LLC developed a solution that focused on improving the chilled water distribution system. The initial goal of the project was to improve space comfort for the 1,500+ students and faculty at Alamo Heights High School. Mesurflo Automatic Balancing Valves Hays Fluid Controls was selected because their Mesurflo valves were superior to their competitors and their technical support was excellent. The Mesurflo automatic balancing valves have an operating range of 2-80 psid. The large operating range and performance of Hays valves allowed the School District to recover the cost of the project through energy savings. Because the new valves performed so well, we were able to load match their central plant and water distribution system to the actual load of the building. Their chilled water distribution system operates at a lower pressure and the overall output of the plant is significantly less. This project will pay for itself in less than one year. - Everett Pastureau, President Syntergy, LLC Hays Fluid Controls ~ 114 Eason Road ~ P.O. Box 580 ~ Dallas, NC ~ ~ R01 Energy Case Study

108 MESURFLO AUTOMATIC FLOW CONTROLS PROVIDE ENERGY SAVINGS FOR ALAMO HEIGHTS INDEPENDENT SCHOOL DISTRICT Results: The comfort complaints have been significantly reduced and the humidity issues have been eliminated. The system operates at lower pressures further reducing maintenance cost associated with the HVAC system. Project cost: $48, Energy Savings: $68,000 Annually Benefit Summary: Mike Hagar Business Director for Alamo Heights ISD: Energy cost for Alamo Heights, including electrical and gas were estimated between $800,000-$900,000 per year. We feel with Syntergy s help, along with energy efficient methods, we can cut cost by 10%15%. Everett Pastureau: President, Syntergy, LLC Secondary chilled water systems are ramped as low as 5-6 psi, and we are still making temp in the building it sits there and runs. Other facilities are running two-three times as hard pushing water around their buildings due to the problems they ve created with an unbalanced system. When you take the step to install a Hays automatic flow control valve, then take the additional steps to rebalance the system, to take advantage of the capabilities that gives you, there is no doubt it saves in energy cost. In this case, it paid back in six months. Hays Fluid Controls ~ 114 Eason Road ~ P.O. Box 580 ~ Dallas, NC ~ ~ R01 Energy Case Study

109 MESURFLO AUTOMATIC FLOW CONTROLS ELIMINATE PIPE NOISE AT NORTHWEST COMMUNITY HOSPITAL Preface: Johnson Controls has been working with Northwest Community Hospital for over 20 years providing temperature controls and service. Recently, the relationship expanded beyond the traditional into a solution based offering. There have been three of these Prime retrofit projects over the last five years. The most recent, Phase 3, involved a complete replacement of the South Patient Tower HVAC system on all three patient floors as well as the basement mechanical room. The previous HVAC system consisted of dual duct boxes on the interior spaces and induction units in all patient rooms. Northwest Community Hospital, Arlington Heights IL Phase 3 South Tower Patient Comfort Initiative The Phase 3 project replaced the dual duct boxes with fan coil units and replaced the Induction units with radiant heating and cooling ceiling panels with ventilation air ducted in over the entry. Situation: The radiant ceiling panels (RCP) have both hot and chilled water lines and each line was installed with a traditional manual balancing valve. Prior to the system being commissioned it was apparent to both the occupants and the project team that there was pipe noise similar to a running faucet or shower line. Some panels made no noise, others were noisy in either the cooling or heating cycle and some panels were noisy in both cycles. Response: First, the copper supply piping to the radiant ceiling panel units was checked for kinks or excessively tight radius bends. Second, air was vented & air troughs were installed. These measures helped but did not eliminate the noise problem. Finally Johnson Controls recommended the use of Hays Mesurflo automatic flow control valves as a possible solution. A few Hays valves were secured and installed as a test. A single Mesurflo valve was installed in one of the noisier rooms in place of the traditional balancing valve on the chilled water line and another on the hot water line. After the Mesurflo valves were installed the noise was eliminated, even when system pump speeds were increased beyond the system differential pressure demand setpoint. Patients experience a quiet environment because Mesurflo valves eliminated pipe noise. Hays Fluid Controls ~ 114 Eason Road ~ P.O. Box 580 ~ Dallas, NC ~ ~ /06

112 To reduce water low noises and prolong equipment life within hydronic heating and cooling systems it is critical that the HVAC system piping is designed based upon maximum recommended velocity limits. The following information is from the Hays Fluid Controls Engineering Team that can help you succeed in this area. HVAC system piping are usually designed based on velocity limits to avoid pipe erosion, cavitation and noise issues. As seen below, the table has been developed using the MRV (Maximum Recommended Velocity) limits of 7 ft/sec to allow piping to be easily and quickly sized. The above limits certainly do vary as a function of estimated operating hours, system operations, pumping system and different applications. Note: The limitations for variable pumping systems are less stringent but generally rises with increase in hours of operation.

146 To reduce water low noises and prolong equipment life within hydronic heating and cooling systems it is critical that the HVAC system piping is designed based upon maximum recommended velocity limits. The following information is from the Hays Fluid Controls Engineering Team that can help you succeed in this area. HVAC system piping are usually designed based on velocity limits to avoid pipe erosion, cavitation and noise issues. As seen below, the table has been developed using the MRV (Maximum Recommended Velocity) limits of 7 ft/sec to allow piping to be easily and quickly sized. The above limits certainly do vary as a function of estimated operating hours, system operations, pumping system and different applications.

152 Customer Supplied Hays Installed ATC Policy Hays will offer and confirm a shipping date of your order upon receipt of correct Automatic Temperature Control Valves and inspection of the same. A list price of $25.00 per package will be added to the total price of each Purchase Order for Hays installation of Customer Supplied Automatic Temperature Control Valves. That price will be discounted based on the current multiplier at the time the PO is received. A complete valve schedule with piping package tagging, control valve model number and connection sizes should be sent prior to the shipment of the those valves to Hays. Control valves received from the customer s supplier must have the Identical Tagging information on each control valve that correlates to the tagging information supplied from the customer for the piping packages ordered. All shipping containers with control valves must be marked with Customer Purchase Order number, originally submitted to Hays, Job I.D. and/or Hays Sales Order #. Assembly of Piping Packages will not start until all Automatic Temperature Control Valves have been received, inspected and found to match the size, type and tagging that was submitted on the Purchase Order. No Partial Shipments! Missing or wrong connection size and non-tagged control valves are the responsibility of the customer and the controls supplier and are subject to the $95.00/ hr rework fee for Hays to sort and tag. Additional requirements or changes made to a piping package after placement of the order will result in a $95.00/hr charge with a minimum of 1 hour plus any additional components used. Not adhering to the above policy will result in a delay of the production process. SPEC-ATCP-CS-001

176 To reduce water low noises and prolong equipment life within hydronic heating and cooling systems it is critical that the HVAC system piping is designed based upon maximum recommended velocity limits. The following information is from the Hays Fluid Controls Engineering Team that can help you succeed in this area. HVAC system piping are usually designed based on velocity limits to avoid pipe erosion, cavitation and noise issues. As seen below, the table has been developed using the MRV (Maximum Recommended Velocity) limits of 7 ft/sec to allow piping to be easily and quickly sized. The above limits certainly do vary as a function of estimated operating hours, system operations, pumping system and different applications. Note: The limitations for variable pumping systems are less stringent but generally rises with increase in hours of operation.

208 Water Source Heat Pump and Fan Coil Piping Packages INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS GENERAL INFORMATION 1. Clean the lines of all foreign material, (welding slag, pipe scale, dirt, thread chips etc.). Upstream installation of a strainer may be necessary in dirty systems. 2. Air should be eliminated from the system prior to startup to assure quiet operation and freedom from water hammer. 3. Flow control valves may be installed horizontally, vertically or any angle in between. Additional straight sections of pipe upstream or downstream of the Automatic flow control valves are unnecessary for proper operation. Straight sections of pipe approximately 10 inside pipe diameters upstream and 5 diameters downstream of Manual Balance Valves is recommended for maximum flow reading accuracy. 4. Standard reducing bushings or flanges may be directly connected to the hose ends if required. 5. The ATC Actuator may be mounted above or along side of piping but must never be mounted where condensation can accumulate or come in contact with electrical or mechanical components. ATC valves marked Stem Up, must be mounted with stem up. 6. All Hays Automatic and Manual Flow Control Valves are marked with direction of flow. Automatic valves will be labeled with the and Manual Valves will be labeled with the Cv. THE FLOW ARROW MUST POINT IN THE DIRECTION OF FLOW FOR PROPER OPERATION. 7. Flow Control Valves, Automatic or Manual, must be located in the RETURN Line. 8. Hays Hose kits must be free of kinks, contact with other objects, sharp bends, tension or torsion. INSTALLATION 1. Threaded components are made with the inch series NPT threads in accordance with ANSI STD B and are intended for use in Building Services Piping meeting the requirements of ASME B Determine which is the Supply Hose and which is the Return Hose. The Strainer is only on the Supply Side. Flow controls are only on the Return Side. The electric valve can be on either side. 3. Swivels are usually mounted closest to the Heat pump, but one may be on the strainer to facilitate flushing. 4. Check application for proper hose length, so as to prevent Kinks, Twists, Sharp Bends, Stretching and Chaffing. 5. ½ through 1-1/4 hoses have a removable threaded adapter. There should be a fiber gasket inside the female swivel end of the hose to prevent leaking when the adapter is connected to the end of the hose. This gasket must be in place to prevent leaking. Do not use any type of tape or compound on the adapter or female swivel connection. These are straight threads and require a gasket to form a proper seal. Use of any sealant material will not prevent leaking and will void any warranty that may be expressed or implied. 6. Apply thread sealant to male pipe threads, starting with the second or third thread from the end. (CAUTION, If factory applied thread sealant is present, DO NOT ADD ADDITIONAL SEALANT) Torque the connection to 75 foot pounds per inch of pipe size minimum. Example: (1 ½, 1.5 X 75= 113 ft lb Min.) (1/4,.25 x 75 = 19 ft lb Min) 7. Rotate the components having Pressure/Temperature Ports or Pressure Taps so they are Not Pointing Down. 8. Sweat fitting valves have their end connections formed to ANSI STD B16.22 requirements and are intended for use in Building Services Piping meeting the requirements of ASME B The Temperature/Pressure rating of the Solder Joint is dependent upon the type of solder used. ANSI STD B16.22 Pressure Ratings should be reviewed prior to selecting a solder and sweating. UNIONS, UNION END PIECES ON VALVES AND THREADED SWEAT ADAPTERS ARE SHIPPED LOOSE AND SHOULD BE UNATTACHED DURING SWEATING. O Rings in the Union End Pieces must be removed and stored on the valve handle or on a nearby PT fitting during the sweating operation. Ball Valves must be in the closed position during sweating. The outside of the tubing, and the inside of the fitting are to be mechanically cleaned and then lightly coated with solder flux. The tube is then inserted one diameter into the fitting, and the CENTRAL PORTION OF THE VALVE BODY WRAPPED WITH A WET RAG, WET SPONGE OR HEAT ABSORBING PUTTY. Heat is never to be applied to the Automatic Temperature Control Valve Body, without first removing all plastic parts and actuators. Valves without removable parts are to be set to the open position to prevent thermal damage. Heat may be applied, either to the tubing or to the end of the fitting so as to achieve solder flow. When the parts have achieved the necessary temperature; solder is to be added to the joint and the joint allowed to cool. The heat is to be applied for the shortest time possible, and never directly to the area where the solder is being applied. The internal parts of the Hays Piping Packages are capable of continuous use at 300 deg. F. but will be quickly damaged at higher temperatures. When soldering vertical assemblies care must be taken not to permit excess solder to drip into the valve. Heat discoloration from the sweating operation should not extend to IOM-HK/PP /11/2014 Page 1 of 2

209 INSTALLATION CONTINUED: the major diameter of the valve body. If disassembled, the valve must be reassembled in the reverse order, with all of the parts returned to their original positions. Hays Valves, Strainers, and Unions are equipped with O Ring Seals in the Union Connection. These seals provide reliable, easy to use connections, but care must be taken to not damage them during installation. Do not heat valve assembly with the O Ring in place. When installing, be sure the O Ring is fully seated in the channel and not twisted or misaligned. The seal is the last item installed prior to tightening the Union Nut to 80 Ft Lbs. for the 2514/2405, and 130 Ft Lbs for the 2524/2407 Hays products. (The Union Nut is shipped loose on sweat fitting 2500 and 2400 Series Products.) If chlorinated flux has been used, all parts are to be flushed thoroughly to avoid premature corrosion failure. 9. Flanged valves are intended for use in Building Services Piping meeting the requirements of ASME B 31.9 and are supplied with ANSI B16.5, 1968, 150 lb. raised face steel flanges. These flanges are to be connected into the piping system utilizing new ASTM A194, GR 2H, nuts, new ASTM A193 GR B7 bolts, size 5/8 inch, and two hardened steel washers under each nut. Remove inlet and outlet covers before installation. Appropriate gasket material must be used when installing flange mounted flow control valves. The thinnest practical gasket should be used whenever possible so as to optimize the joint performance. A non-metallic based lubricant such as oil or graphite is to be applied to the nuts and bolts, and the assembly uniformly torqued to 120 ft lb. for 4 Flanges, 200 ft lb. for 6 & 8 Flanges, and 320 ft lb. for 10 Flanges. Bolts should be torqued in at least three even steps using a star or crossing pattern until the final torque is reached. 10. Welded valves are to have their plastic inlet and outlet covers removed, and the valve placed in the pipe so as to minimize the entrance of weld slag into the plumbing. Welding is to be performed in accordance with the applicable requirements required for the system. 11. Inspect installation or Leaks, Kinks, Twists, Sharp Bends, Stretching and Chaffing. OPERATION 1. For optimum operation, air entrainment in the system must be eliminated. The flow control valve must remain filled with fluid. The system must be clean and free of foreign materials. 2. The Hays Hose Kits and Piping Packages must only be used with fluids that are compatible with, Iron, Brass, Santoprene and EPDM materials. The temperature during operation must be limited to the range of 32 F to 225 F. 3. Hose kits and Piping Packages are fully compatible with Ethylene Glycol and Propylene Glycol with all concentrations. MAINTENANCE 1. General maintenance is not required for Hays Hose Kits or Piping Packages, however if the system experiences large amounts of pipe scale due to poor water conditions, as sometimes is found in older or retrofit systems, some maintenance may be required. Provisions should be made to keep the system clean. Proper water treatment is also recommended. 2. Periodically check to make sure the hoses are free from strain or damage, and if Manual Balancing Valves are being used, that their handle is in its proper balancing position.

229 To reduce water low noises and prolong equipment life within hydronic heating and cooling systems it is critical that the HVAC system piping is designed based upon maximum recommended velocity limits. The following information is from the Hays Fluid Controls Engineering Team that can help you succeed in this area. HVAC system piping are usually designed based on velocity limits to avoid pipe erosion, cavitation and noise issues. As seen below, the table has been developed using the MRV (Maximum Recommended Velocity) limits of 7 ft/sec to allow piping to be easily and quickly sized. The above limits certainly do vary as a function of estimated operating hours, system operations, pumping system and different applications. Note: The limitations for variable pumping systems are less stringent but generally rises with increase in hours of operation.

248 Automatic Balancing Hosekit I-O-M Index Type Page Watersource Heat Pump Hosekit & Fan Coil Package, Installation, Operation Manual IOM-HK/PP Watersource Heat Pump Hose Kit Performance Specification Summary HK-SPEC-SUM Terms & Conditions Terms & Conditions A B H K ABHK

249 Water Source Heat Pump and Fan Coil Piping Packages INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS GENERAL INFORMATION Clean the lines of all foreign material, (welding slag, pipe scale, dirt, thread chips etc.). Upstream installation of a strainer may be necessary in dirty systems. Air should be eliminated from the system prior to startup to assure quiet operation and freedom from water hammer. Flow control valves may be installed horizontally, vertically or any angle in between. Pressure/Temperature Ports should be pointed down, as they may become clogged. Additional straight sections of pipe upstream or downstream of the Automatic flow control valves are unnecessary for proper operation. Straight sections of pipe approximately 10 inside pipe diameters upstream and 5 diameters downstream of Manual Balance Valves is recommended for maximum flow reading accuracy. Standard reducing bushings or flanges may be directly connected to the hose ends if required. The ATC Actuator may be mounted above or along side of piping but must never be mounted where condensation can accumulate or come in contact with electrical or mechanical components. ATC valves marked Stem Up, must be mounted with stem up. All Hays Automatic and Manual Flow Control Valves are marked with direction of flow. Automatic valves will be labeled with the and Manual Valves will be labeled with the Cv. THE FLOW ARROW MUST POINT IN THE DIRECTION OF FLOW FOR PROPER OPERATION. Flow Control Valves, Automatic or Manual, must be located in the RETURN Line. Hays Hose kits must be free of kinks, contact with other objects, sharp bends, tension or torsion. INSTALLATION Threaded components are made with the inch series NPT threads in accordance with ANSI STD B and are intended for use in Building Services Piping meeting the requirements of ASME B Determine which is the Supply Hose and which is the Return Hose. The Strainer is only on the Supply Side. Flow controls are only on the Return Side. The electric valve can be on either side. Swivels are usually mounted closest to the Heat pump, but one may be on the strainer to facilitate flushing. Check application for proper hose length, so as to prevent Kinks, Twists, Sharp Bends, Stretching and Chaffing. ½ through 1-1/4 hoses have a removable threaded adapter. There should be a fiber gasket inside the female swivel end of the hose to prevent leaking when the adapter is connected to the end of the hose. This gasket must be in place to prevent leaking. Do not use any type of tape or compound on the adapter or female swivel connection. These are straight threads and require a gasket to form a proper seal. Use of any sealant material will not prevent leaking and will void any warranty that may be expressed or implied. Apply thread sealant to male pipe threads, starting with the second or third thread from the end. (CAUTION, If factory applied thread sealant is present, DO NOT ADD ADDITIONAL SEALANT) Torque the connection to 75 foot pounds per inch of pipe size minimum. Example: (1 ½, 1.5 X 75= 113 ft lb Min.) (1/4,.25 x 75 = 19 ft lb Min) Rotate the components having Pressure/Temperature Ports or Pressure Taps so they are Not Pointing Down. Sweat fitting valves have their end connections formed to ANSI STD B16.22 requirements and are intended for use in Building Services Piping meeting the requirements of ASME B The Temperature/Pressure rating of the Solder Joint is dependent upon the type of solder used. ANSI STD B16.22 Pressure Ratings should be reviewed prior to selecting a solder and sweating. UNIONS, UNION END PIECES ON VALVES AND THREADED SWEAT ADAPTERS ARE SHIPPED LOOSE AND SHOULD BE UNATTACHED DURING SWEATING. O Rings in the Union End Pieces must be removed and stored on the valve handle or on a nearby PT fitting during the sweating operation. Ball Valves must be in the closed position during sweating. The outside of the tubing, and the inside of the fitting are to be mechanically cleaned and then lightly coated with solder flux. The tube is then inserted one diameter into the fitting, and the CENTRAL PORTION OF THE VALVE BODY WRAPPED WITH A WET RAG, WET SPONGE OR HEAT ABSORBING PUTTY. Heat is never to be applied to the Automatic Temperature Control Valve Body, without first removing all plastic parts and actuators. Valves without removable parts are to be set to the open position to prevent thermal damage. Heat may be applied, either to the tubing or to the end of the fitting so as to achieve solder flow. When the parts have achieved the necessary temperature; solder is to be added to the joint and the joint allowed to cool. The heat is to be applied for the shortest time possible, and never directly to the area where the solder is being applied. The internal parts of the Hays Piping Packages are capable of continuous use at 300 deg. F. but will be quickly damaged at higher temperatures. When soldering vertical assemblies care must be taken not to permit excess solder to drip into the valve. Heat discoloration from the sweating operation should not extend to IOM-HK/PP-002 EC /16/2014 ABHK Page 1 of 2

250 INSTALLATION CONTINUED: the major diameter of the valve body. If disassembled, the valve must be reassembled in the reverse order, with all of the parts returned to their original positions. Hays Valves, Strainers, and Unions are equipped with O Ring Seals in the Union Connection. These seals provide reliable, easy to use connections, but care must be taken to not damage them during installation. Do not heat valve assembly with the O Ring in place. When installing, be sure the O Ring is fully seated in the channel and not twisted or misaligned. The seal is the last item installed prior to tightening the Union Nut to 80 Ft Lbs. for the 2514/2405, and 130 Ft Lbs for the 2524/2407 Hays products. (The Union Nut is shipped loose on sweat fitting 2500 and 2400 Series Products.) If chlorinated flux has been used, all parts are to be flushed thoroughly to avoid premature corrosion failure. Flanged valves are intended for use in Building Services Piping meeting the requirements of ASME B 31.9 and are supplied with ANSI B16.5, 1968, 150 lb. raised face steel flanges. These flanges are to be connected into the piping system utilizing new ASTM A194, GR 2H, nuts, new ASTM A193 GR B7 bolts, size 5/8 inch, and two hardened steel washers under each nut. Remove inlet and outlet covers before installation. Appropriate gasket material must be used when installing flange mounted flow control valves. The thinnest practical gasket should be used whenever possible so as to optimize the joint performance. A non-metallic based lubricant such as oil or graphite is to be applied to the nuts and bolts, and the assembly uniformly torqued to 120 ft lb. for 4 Flanges, 200 ft lb. for 6 & 8 Flanges, and 320 ft lb. for 10 Flanges. Bolts should be torqued in at least three even steps using a star or crossing pattern until the final torque is reached. Welded valves are to have their plastic inlet and outlet covers removed, and the valve placed in the pipe so as to minimize the entrance of weld slag into the plumbing. Welding is to be performed in accordance with the applicable requirements required for the system. Inspect installation or Leaks, Kinks, Twists, Sharp Bends, Stretching and Chaffing. OPERATION For optimum operation, air entrainment in the system must be eliminated. The flow control valve must remain filled with fluid. The system must be clean and free of foreign materials. The Hays Hose Kits and Piping Packages must only be used with fluids that are compatible with, Iron, Brass, Santoprene and EPDM materials. The temperature during operation must be limited to the range of 32 F to 225 F. Hose kits and Piping Packages are fully compatible with Ethylene Glycol and Propylene Glycol with all concentrations. MAINTENANCE General maintenance is not required for Hays Hose Kits or Piping Packages, however if the system experiences large amounts of pipe scale due to poor water conditions, as sometimes is found in older or retrofit systems, some maintenance may be required. Provisions should be made to keep the system clean. Proper water treatment is also recommended. Periodically check to make sure the hoses are free from strain or damage, and if Manual Balancing Valves are being used, that their handle is in its proper balancing position.
