3 Series ir Release s Stainless Steel T Trim Standard Stainless Steel Floats Guaranteed Easily Serviced Without Removal From Pipeline Working Pressures to 00 PSI Engineered For Drip Tight Seal t Low Pressures Cla-Val Series ir Release s are designed to vent entrained air that collects at high points in a pipeline. This valve continuously eliminates air from a system by releasing small quantities of air before large air pockets can occur. In many installations, continuing accumulations of air in the pipeline (lacking air release valves); cause flow capacity to slowly decrease; power consumption slowly increases; unnoticeable at first, until flow drops dramatically, even stopping due to air blocks in the piping. nother problem resulting from excessive air accumulation is un-explained pipeline rupture. These ruptures are passed off as the result of ground settling or defective pipe, Where as in reality its large air pockets that greatly increase pressure surges (normally occurring) when flow stops and starts causing the rupture. During normal pipeline operation, air accumulation at the high point will displace the liquid within the air valve and lower the water level in relation to the float. s level of the liquid lowers, where the float is no longer buoyant, the float drops and opens the valve orifice seat and permitting accumulated air to be exhausted to atmosphere. fter air is released, the liquid level in the air valve rises and closes the valve orifice seat. This cycle automatically repeats as air accumulates inside the air release valve, thereby preventing the formation of air pockets Installation Series ir Release s are typically installed at highpoints in pipelines and at regular intervals, of approximate / mile, along uniform grade line pipe. Mount the unit in the vertical position on top of the pipeline with an isolation valve installed below each valve in the event servicing is required. vault with adequate air venting and drainage is recommended.

4 IR RELESE VLVE DT FOR WTER ND ir Release Sizing for Water and Wastewater Pipelines. ir release valve sizing requires determining the volume of air that must be released from pipeline high points during normal operation and the diameter of the pipeline. Series ir Release s are primarily used to continuously release pockets of air (as they develop) from high points. Hence it is not critical to determine exact volume of air to be released.. If the volume of air to be released has been determined, then use the venting capacity chart on page to assist in sizing the air release valve. Use maximum pipeline operating pressure (in psi) and flow (in SCFM) to determine orifice size. Select the largest inlet size for each valve to insure adequate venting capacity. INSTLLTION TIPS. The effectiveness of Series ir Release is dependent upon it being located at appropriate high points in a pipeline and at uniform intervals of approximately 00 feet on horizontal pipelines.. There are four variables that can cause an air pocket to form slightly downstream of the true high point in a piping system:. Severity of the slope adjacent to the high point or change of gradient. Velocity of the liquid. Texture of the inside surface of the pipe being used. Viscosity of the fluid It is recommended where an air pocket can form slightly downstream of the high point, to install additional Series ir Release at this point.. Cla-Val has available, upon request, a Slide Rule ir Calculator. It will greatly reduce the amount of time to size valves for pipeline service.

14 Sizing Guide for - ir and Vacuum ir s and Vacuum Wastewater ir and Vacuum Sizing - Combination ir Vacuum s - Vacuum reaker s. Series ir and Vacuum s should be sized to handle the maximum amount of air to be exhausted or admitted into the pipeline and not exceed an acceptable pressure differential across the valve.. Each high point or change in grade must be examined independently when determining valve size. Use the steepest slope for calculations.. Use the flow capacity charts () and () on page to assist sizing ir and Vacuum s.. Determine the smallest valve size capable of exhausting air equal to the filling rate of the pipeline in CFS while not exceeding a pressure differential of psi across the valve orifice. (ased on pump capacity). The following formula is recommended to calculate the rate of flow in CFS for filling the pipeline: CFS = GPM. Where: CFS = Cubic feet per second GPM= Gallons per minute. Determine the smallest valve size capable of admitting air equal to the potential flow in CFS while not exceeding a pressure differential of psi across the valve orifice. (ased on gravity flow). The following formula should be used to calculate the rate of flow in CFS that can occur within the pipeline under gravity flow conditions. (During Initial Filling During Intentional Draining During Pipeline Rupture) Q =.000 C S D Where: Q = Flow of water in cubic feet per second C = Coefficient in Chezy s formula = 0 S = Slope in feet per foot of length D = Inside pipe diameter in inches. If thin wall pipe is being used, the risk of pipeline collapse due to the formation of vacuum must be considered. The following formula may be used to calculate the collapsing pressure of thin walled cylindrical steel pipe using a safety factor of four: P =,0,000 T D Where: P = Collapsing pressure in psi T = Thickness of pipe in inches D = Diameter of pipe in inches. For other pipe materials or thickness consult pipe manufacturer for pipe collapsing pressure.. Determine the smallest valve size capable of admitting the required air in CFS (as found in step ) without exceeding the collapsing pressure (as found in step ) or psi, whichever is less. Do not exceed a pressure differential greater than psi.. Finally compare the valve size determined in step with the valve size determined in steps or. If they differ, always select the larger valve size.

16 Series ir and Vacuum s Provides High Capacity ir Venting and ir Intake Stainless Steel T Trim Standard Stainless Steel Floats Guaranteed Fully Ported s - No Restrictions Designed For Drip Tight Seal t Low Pressures The Cla-Val Series ir and Vacuum is designed to perform two separate functions. First, it will allow large quantities of air to be exhausted from the pipeline as it is being filled with water. When this air has been vented completely, water will enter the valve causing the float to seal tightly against the seat to prevent water flow. Secondly, if the line is being drained, either intentionally or as a result of pipeline breakage, the valve responds to the loss in pressure and opens. This allows air to re-enter the pipeline and prevents potentially damaging vacuum from developing. Note: The Series does not open under pressure to exhaust small quantities of air which may collect at high points during system normal operation. Series ir Release is required for this function. Note: See Sizing Guide Pages & Installation Series ir and Vacuum s should be installed at high points or at grade changes within the pipeline. Mount the unit in the vertical on top of the pipeline with isolation valve below each valve in the event servicing is required. vault with adequate venting and drainage should also be provided. Purchase Specifications The air and vacuum valve shall be able to automatically exhaust large quantities of air during filling of a pipeline and allows air to re-enter pipeline during the draining or when a negative pressure occurs. The inlet and outlet of the air and vacuum valve shall have the same cross-section area as the pipe size. The float shall be guided by a stainless steel bottom guide shaft. The " and larger valve floats shall have top and bottom guide shafts of hexagonal cross section and have a protective steel discharge hood.

36 IR ND VCUUM VLVES FOR (WELL SERVICE) PUMP /" - " " and Larger Stainless Steel T Trim Standard Stainless Steel T Floats Guaranteed ir Throttling Device (Double Port) rrestor Check Device (nti-shock) 00% Vacuum Protection - No Restrictions Engineered For Drip Tight Seal t Low Pressures Series Well Service ir s regulate air discharge from the pump column to prevent shock and air entering the system with each start. Conversely with each pump stop, full flow unrestricted air, is allowed back into the column preventing vacuum forming, which can damage pump steals, but also to prevent the pump restarting against a full head in the column because vacuum will prevent the pump column to drain. Under this condition severe damage to the pump, controls and piping can occur. ll the preceding is accomplished by means of a unique air throttling device (double port) and an arrestor check with built in antishock feature. Well service air vacuum valves, once closed and pressured do not open to air release under pressure. See series ir Release s page. Installation The Series Well Service is typically installed between the pump discharge and check valve. Mount the unit in the vertical position on top of the pipeline with an isolation valve installed below the valve in the event servicing is required. Provide adequate air venting inside the pump station and from air valve vaults on pipelines. General Specifications Sizes /", ", ", " Threaded Inlet with double port throttling device " through " lb. flanged Inlet or 0 lb. flanged Inlet with arrestor check Pressure Ratings 0 psi 00 psi specify when operating pressure below 0 PSI Temperature Range Water to 0 F s: ody and Cover: Cast Iron STM, Class Float: Stainless Steel T ir Internal Parts: Stainless Steel T rrestor Check: Stainless/ronze Seal: una-n Rubber Design / Purchase Specifications The Well service air valves shall automatically exhaust large quantities of air in the pump column during pump start-up and allow air to re-enter the column during pump shut-down. The air valve shall be designed for installation between outlet of vertical turbine pumps and the inlet of the pump check valve. The inlet and outlet area of the air valve shall be equivalent to the valve pipe size same cross-section area. The valve shall have NPT Threaded or NSI Flanged inlet and outlet. The float shall be guided by a hexagonal stainless steel guide shaft and seal drip-tight against a synthetic rubber seal. " and larger valve float shall be double guided and a protective steel discharge hood provided. The float shall be of all stainless steel construction and capable of withstanding maximum system surge pressure without failure. The body and cover shall be concentrically located and of cast iron and the valve all internal parts shall be T stainless steel with una-n rubber seat. /,, and Well Service ir s to be supplied with a double ported throttling device to regulate the discharge of air from the pump column to prevent shock to the pump with each start. and larger well service valves to be supplied with an arrestor check to prevent shock to the pump with each pump start. ll Well Service ir s shall allow full un-restricted air flow into the pump column, to prevent any vacuum from forming, with each pump stop.

These devices permit regulating the volume of air discharge from the vertical pump column thereby to cushion the shock from the rising water column, as it impacts against a closed pump, discharge check valve or control valve. y utilizing this type air valve damage to the vertical turbine pump. Piping and controls will be prevented. Field adjustment of this air throttling device is quite simple and requires no special tools. Threaded Inlet /" - " Series Well Service s (Light Duty) well service valves are supplied without air throttle device. Instead it is fitted with a water diffuser that function like a water faucet bubbler to break down a solid column of water into small streams there by allowing the water to raise the air valve float slowly into the closed position. Recommended where operating pump pressure are below 0 PSI and GPM velocities less than per/sec Flanged Inlet " and Larger Flanged Series Well & Pipeline service air valves are supplied with rrestor Check s, function to stop the flow of water, (for a fraction of a second) entering the upper chamber of the air valve. The rrestor Check then opens instantly, water enters the air valve, all air is exhausted and the air valve shuts. This rrestor Check action allows for a slow non shock air valve shut-off. To prevent pump or pipeline damage the shut-off/open action of the arrestor check occurs practically instantaneously. It is self regulating and requires no adjustment in the field. rrestor Check air valves are recommended at high points where velocities approach 0 / second in the main line. How to Select Size:. Refer to desired model chart on pages, or.. Determine pump flow capacity (in GPM) at little or no head condition.. Read corresponding valve size. If flow capacity is near maximum of range, select next larger size as recommended. Flanged outlet available at extra cost. Consult factory for larger sizes Note: Note: Manufactured to meet NSI/WW C-0 It is sound engineering practice that outlets of air valves, inside the pump station, be piped to a drain to eliminate high pitched noise of air exhausting.

Threaded Flanged During normal pipeline operation, air accumulation and buoyancy cause the float ball to lower or lift. s the water level lowers inside the valve, small amounts of accumulated air are released through the small orifice. Once air is released, the patented float poppet system closes drip tight. servicing is simple because the entire float poppet system, can be replaced without removal of the valve body from the pipeline.

Standard valves are designed to open with minimal (/ psi) pressure differential across the orifice. Higher or lower relief settings are available. The Vacuum reaker (Large orifice combined with ir Release (small orifice) are normally closed. ut when installed at points where water column separation can occur, both orifices open admitting air into pipeline, then instantly close to trap air and thereby cushioning rejoining of the water column. In this manner severe pressure surge/water hammer is prevented as the system returns to normal operation.

55 Series -WW WSTEWTER SERVICE IR RELESE VLVES Note: For sizing see page Stainless Steel T Trim Standard Stainless Steel Floats Guaranteed Easily Serviced Without Removal From Pipeline Engineered For Drip Tight Seal t Low Pressures Optional ackwash Kit vailable The Cla-Val series WW ir Release is specially designed for sewage service. It will protect pipelines from entrained air or gases that collect at high points in sewage pipelines. This valve effectively eliminates air from a system by releasing small amounts of air before large air pockets can occur. In extreme cases, the continued accumulation of air without release valves can actually stop flow completely. Increased power consumption and associated power costs can be anticipated if systems are not properly designed to release accumulated air. During normal operation, air and gas accumulation will displace the liquid within the valve and lower the liquid level in relation to the float. When the level of the liquid lowers to where the float is no longer buoyant, the float will lower and using a mechanical lever will open the valve seat to permit the accumulated air to be exhausted to atmosphere. s air is released, liquid level in the valve raises the float and closes the valve seat. This cycle is automatically repeated as often as necessary. Installation Series WW ir Release s are typically installed at high points in pipelines and at regular intervals of approximately / mile, along horizontal pipelines. Mount the unit in the vertical position on top of the pipeline with an isolation valve installed below each valve in the event servicing is required. vault with adequate venting and drainage should also be provided. For regular cleaning to keep sewage equipment in good working condition use the optional customer installed WKT ackwash Kit with back flushing hose and quick disconnect couplings.

58 Series -WW WSTEWTER SERVICE IR ND VCUUM VLVES Stainless Steel T Trim Standard Stainless Steel Floats Guaranteed Fully Ported s - No Restrictions Designed For Drip Tight Seal t Low Pressures Optional ackwash Kit vailable The Cla-Val Series WW ir and Vacuum is designed to perform two separate functions in a sewage or wastewater system. First, it will allow large quantities of air to be exhausted from the pipeline as it is being filled. When this air has been vented completely, liquid will enter the valve causing the float to seal tightly against the seat. Secondly, if the line is being drained, the valve responds to the loss in pressure and opens. This allows air to re-enter the pipeline and prevents potentially damaging vacuum from developing. The Series WW does not open under pressure to exhaust small quantities of air which may collect at high points during system normal operation. Model WW ir Release is required for this function. For both functions, select Model WW Combination ir Release and Vacuum. Note: For Sizing, See Formula Page. Installation Series WW ir and Vacuum s should be installed at high points or at grade changes within the pipeline. Mount the unit in the vertical position on top of the pipeline with isolation valve below each valve in the event servicing is required. vault with adequate venting and drainage should also be provided. For regular cleaning to keep sewage equipment in good working condition use the optional customer installed WKT ackwash Kit with back flushing hose and quick disconnect couplings. Purchase Specifications The air and vacuum valve shall be able to automatically exhaust large quantities of air during filling of a pipeline and allows air to re-enter pipeline during the draining or when a negative pressure occurs. The inlet and outlet of the valve shall have the same cross-section area. The float shall be guided by a synthetic rubber seal.

It functions to exhaust large quantities of air in the pipeline during the filling cycle and to admit air, as necessary, to prevent a potentially dangerous vacuum from forming when being emptied either intentionally or as a result of pipeline breakage. Note: For sizing see Formula page. Installation The Series WW Combination ir should be installed at high points and grade changes within the pipeline. Mount the unit in the vertical position on top of the pipeline with an isolation valve installed below each valve in the event servicing is required. vault with adequate venting and drainage should also be provided. For regular cleaning to keep sewage equipment in good working condition use the optional customer installed WKT ackwash Kit with back flushing hose and quick disconnect couplings. Purchase Specification The combination air valve shall combine the operating features of both an air and vacuum valve and an air release valve in one housing. The air and vacuum valve portion shall automatically exhaust large quantities of air during the filling of the pipeline and automatically allow air to reenter the pipeline when the internal pressure of the pipeline approaches a negative value due to column separation, draining of the pipeline, or other emergency. The air release valve portion shall automatically release small amounts of air from the pipeline while it is under pressure. The inlet and outlet of the valve shall have the same crosssection area. The float shall be guided by a stainless steel guide shaft and seat drip-tight against a synthetic rubber seal. The float shall be of all stainless steel construction and capable of withstanding maximum system surge pressure without failure. The body and cover shall be concentrically located and of cast iron and all valve internal parts shall be T stainless steel with una-n rubber seat.

90 Series Flex-Check Full Pipe Size Flow rea Drop Tight ing Non-Slam Closure Fusion onded Epoxy NSF- Optional Return Flow ctuator Optional Return Flow ctuator Cla-Val Flex-Check Specifications The check valve shall be of the Flex-Check full body flanged type, with a domed access cover and only one moving part - the flexible valve disc. The Cla-Val Model Flex-Check is designed for long service life and maintenance free check valve operation compared to traditional swing check valves. It has a full-flow area body with integral seat at angle to reduce head loss. This minimizes disc travel to degrees for improved no-slam check action and for reliable vertical up flow operation even on slurry applications. ody and Cover are fusion bonded NSF- epoxy coated for long service life on potable and non-potable systems. Unique onepiece steel and nylon reinforced una-n rubber disc assembly flexes to eliminate traditional metal hinge problems. During system flowing conditions the disc flexes up to the open position allowing unrestricted flow through the valve. When system reverse flow conditions occur the disc flexes down to the closed position for drop-tight seal preventing reverse flow. The flex-disc reliability is test-proven to over one million cycles. The optional Return Flow ctuator offers manual opening for pump priming, back flushing, draining lines, or system testing needs and is easy to field install. The valve body shall have full flow equal to nominal pipe diameter at any point through the valve. The seating surface shall be on a angle to minimize disc travel and shall include a port for installation of a screw type return flow actuator for manually activated return flow capabilities. The top access port of the body shall be full size, allowing removal of the disc without removal of the valve from the pipeline. The cover shall be domed to create a flushing action around the disc when valve is open. The valve body and cover shall be STM Grade --, Class Ductile Iron coated and lined with an NSI/NSF approved fusion bonded epoxy coating. The Model Flex-Check shall be designed, manufactured, and tested in accordance with NSI/WW Standard C- 0. STREMLINED CONTOURED ODY STROKE ONE PIECE UN-N DISC STEEL & NYLON REINFORCED The disc shall be one-piece construction, precision molded with an integral O-ring type sealing surface and contain steel and nylon reinforcements in the central disc area and in the flex support area. The non-slam closing characteristic shall be provided through a short disc stroke and disc return action. The disc shall be una-n (NR), STM D0000-G.
