Hydrant, bury depth of 1.5 meters to bottom of pipe: head loss = max. 0.069 bar per hose connection flow = min. 946 L/min per hose connection OPERATION AND MAINTENANCE The AVK modern hydrant is designed to be an easily operated, low torque, high flow fire hydrant. The thrust bearing hydrant requires a minimum of torque to operate. It is possible to damage the hydrant by forcing it beyond its limits of travel with excess torque; therefore: 1. Check direction of opening as marked on the hydrant weathershield. 2. To open, turn the operating nut in the opening direction, indicated by an arrow on the weathershield, until the main valve, is fully open (approximately 19 to 21 turns). The stop nut, should prevent the hydrant from opening beyond the fully open position. Do not force the hydrant in the opening direction beyond full open as indicated by sudden resistance to turning. If water does not flow when the hydrant is open, it is probably due to a closed valve upstream from the hydrant. 3. To close, turn the operating nut until the main valve stops off the flow. It is not necessary to close this type of hydrant with great force. Once the flow has stopped, loosen the operating nut in the opening direction, 1/2 to 1 turn to take the strain off the operating parts of the hydrant and to make it easier to open the hydrant.

Dry barrel fire hydrants Dry barrel fire hydrants are primarily designed for areas with frost, where the water main is located below ground frost zone. The series 27 dry barrel hydrant has two drain outlets located just above the water main level. The main valve disc is designed with the purpose of flushing the drain channels for soil and other impurities during opening. These impurities could lead to damage of the main valve disc. After turning the operation key 2 to 3 times the drain will stop flushing, and the barrel will be filled with water which will flow directly into the hoses and pumper connection or whatever is connected. Furthermore, when the hydrant is closed after service, the barrel will drain the water through the drain holes in the base. Therefore, it is important to make sure that the base is surrounded by gravel allowing the hydrant to drain and flush without washing off the soil. If not, this could result in under mining of the pavement. AVK dry barrel fire hydrants meet or exceed AWWA C-502 and are UL/ULC listed and FM approved. The fire hydrants are designed for high performance, easy repair and minimum end user costs for labor and inventory. Series 27 is available in different configurations. 6 Valves and hydrants for fire protection

Post indicators and gate valves for post indicators Post indicators are mounted end to end with the extension spindle connecting the valve. It is mounted in places where direct access is impossible. It could be gate valves mounted on a water ring main in a factory area, such as oil refineries, chemical plants or airports. The post indicator indicates if the valve is in open or closed position. According to government regulations, it must be easy for firemen to see if the valve is open or closed, even at a long distance. The post indicator signs OPEN and SHUT are mounted on the target according to valve size. The post indicator valves are used for underground installation in fire protection systems. The post indicator flange is incorporated in the top gland, giving a compact design. The basic valve construction is, like the construction of valves Vejle Brandvæsen for water supply, characterized by a fully rubber coated wedge, full and straight bore, low torque operation and O-ring stem seals replaceable under pressure.

Air valve - for safety in your fire fighting pipe system K-060/62 HFNS Applications The K-HF NS series is adapted for clear water installation in dry fire protection where the filling and drainage operation has to be done quickly. Main features Reliable operation that reduces water hammer incidents. The controlled discharge of air (NS) will reduce surge effects and provide a silent closure of the air valve. Operation How to choose the right air valve? We offer you this service! - using a software program for the sizing and location of the air valve. The air and vacuum valve discharge air at high flow rates during the filling of the system and admits air at high flow rates during the drainage, pump shut-off or at water column separation. Description The K-060 NS series air and vacuum valve discharges air during the filling or charging of the system and admits air into the system during system drainage, valve or pump shut-off. The built-in throttling device on the non-slam disc will allow the graduated opening and closing of the disc orifice. Technical data According to the standard EN 1074-4 Working pressure type K-060 HFNS: PN 10 (0,1 à 10 bar) PN 16 (0,2 à 16 bar) Working pressure type K-062 HFNS: PN 25 (0,2 à 25 bar) Pressure test: each air valves are tested before leaving the plant at 1,5 x nominal pressure.

Non-slam combination air valve operation in rapid filling of the pipeline When water, rapidly filling the pipeline, pushes the air out through the air valve, a differential pressure is created across the orifice. When this differential pressure reaches a prefixed level (usually it will be prefixed at 0,02-0,03 bar) the orifice disc will close. Air will continue to come out through the small orifice disc - until all the air will be exhausted and water will Non-slam disc: The built-in throttling device on the non-slam disc of the K-60-HFNS combination air valve will allow for the graduated opening and closing of the disc orifice reach the kinetic float. This double stage kinetic air discharge prevents the slam effect therefore suppresses water hammer. When water reaches the kinetic float, it lifts it up, closing the kinetic orifice and completing the kinetic cycle. The throtteling device will come back to its normal open position. Draining. When water is drained out of the pipeline, the resulting pressure drop lets the kinetic float fall down, opening the orifice fully for intake of high volume of air into the line.

Gate valves for sprinkler systems AVK resilient seated gate valves are designed with a fully vulcanized rubber wedge. With this design no iron parts are exposed to the medium, and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber. The rubber is vulcanized onto the wedge by AVK GUMMI A/S, one of Europe's leading manufacturers of high technology moulded rubber components. The high quality of AVK rubber is characterized by: Smell and taste response characteristics highly suitable for the food industry Very low deformation ensuring optimum sealing High impact resistance preventing corrosion Low friction ensuring low closing torques EPDM rubber for water supply Standard stem sealing system applications to DIN standard. NBR wiper ring polyamid bearing with 4 O-rings EPDM rubber manchette OS&Y stem sealing system NBR wiper ring polyamid bearing with 2 O-rings, replaceable under pressure with the valve fully open. O-ring protects the antifriction washers 24 Valves and hydrants for fire protection

Gate valves with flanges and grooved ends -pin indicator and OS&Y Grooved end valves with pin indicator - series 06/37 The valves fit the quick clamp system and are machined according to AWWA C606. The grooved end on the valve is fixed to the pipe material e.g. steel or cast iron - by means of standard clamping couplings. Flanged valves OS&Y - series 45/56 The OS&Y gate valves with flanges are used in above ground installations. Due to the rising stem it is easy to recognize the valve position, open or closed, even at a distance. Over the past 75 years, the grooved end clamping system has proved to be one of the fastest and most efficient ways of joining pipes due to its high degree of flexibility and rigidity, as well as a fast and easy assembly. The basic valve design is characterized by a fully rubber coated wedge, full and straight bore, low torque operation and O-ring stem seals replaceable under pressure. The system absorbs vibrations and noise transmission through the system. It has a certain degree of angular deflection of the pipe joints and alignment in all positions 360º around the pipe axis. Therefore, the system has gained a footing in high rise buildings where vibrations and stress of pipe systems are of significant importance. The series 06/37 valve is a further development of the wellknown VdS-approved gate valve series 06/35 which was originally designed for sprinkler systems. This industry has recognised the time saving and effective way to connect pipes and fittings. GGG-50 DN 50-300 VdS-approved DN 50-200 DN 65-300 (21/2" - 12") UL-listed, FM-approved Flanged valves with pin indicator - series 06/35 The light weight flanged gate valve is very suitable for use in fire protection systems as an isolating gate valve for maintenance purpose. The pin indicator indicates the wedge position. Micro switches for remote indication of the wedge in open or closed position are available as an optional extra. The basic valve construction is, like the construction of valves for water supply, characterized by a fully rubber coated wedge, full and straight bore and 3 independant stem seals.

Series 27 - flow/pressure loss/operation The AVK dry barrel hydrant meets or exceeds the requirements of FM 1510 and UL 246. Hydrant, bury depth of 1.5 meters to bottom of pipe: head loss = max. 0.069 bar per hose connection flow = min. 946 L/min per hose connection Hydrant with pumper connection: head loss = max 0.345 bar, when flow = 3785 L/min OPERATION AND MAINTENANCE The AVK modern hydrant is designed to be an easily operated, low torque, high flow fire hydrant. The thrust bearing hydrant requires a minimum of torque to operate. It is possible to damage the hydrant by forcing it beyond its limits of travel with excess torque; therefore: 1. Check direction of opening as marked on the hydrant weathershield. 2. To open, turn the operating nut in the opening direction, indicated by an arrow on the weathershield, until the main valve, is fully open (approximately 19 to 21 turns). The stop nut, should prevent the hydrant from opening beyond the fully open position. Do not force the hydrant in the opening direction beyond full open as indicated by sudden resistance to turning. If water does not flow when the hydrant is open, it is probably due to a closed valve upstream from the hydrant. 3. To close, turn the operating nut until the main valve stops off the flow. It is not necessary to close this type of hydrant with great force. Once the flow has stopped, loosen the operating nut in the opening direction, 1/2 to 1 turn to take the strain off the operating parts of the hydrant and to make it easier to open the hydrant. Weathershield note: open left shown. Stop nut resting against internal lubrication reservoir in the nozzle section. 32 Valves and hydrants for fire protection

Technical appendix Corrosion protection and Rubber technology Blast cleaning All cast components are blast cleaned according to ISO 12944-4, SA 2½. The components are cleaned in a shot-blasting plant. The cleaned parts are held with fibre-free gloves and are transported to the oven without delay according to GSK specifications. When viewed, the surface shall be visibly free from oil, grease, dirt, mill scale, rust, paint and foreign objects. Any remaining traces of contamination shall show only as slight stains in the form of spots or stripes. The surface shall have a uniform metallic colour, visually and compared with test plates. The process ensures an optimum bonding of the coating, which is essential for corrosion resistance. Epoxy coating The valve bodies and bonnets are epoxy coated according to DIN 30677-2 and GSK guidelines. The epoxy coating is electrostatically applied in an enclosed coating booth, max. 4 hours after the valve components were blast cleaned. The epoxy powder melts between 200-230ºC, and cures when in contact with the cleaned and preheated component, ensuring an optimal bonding. Test procedure Coating thickness: The coating layer thickness shall be no less than 250 μ. Pore-free coating: The coating must be completely free of penetrating pores to avoid subsequent corrosion of the casting underneath. A 3V holiday detector with a brush electrode is used to electrically reveal and locate any pores in the coating. Impact resistance: The impact resistance test is carried out at least 24 hours after the coating process by means of a stainless steel cylinder dropped on the coating surface through a one meter long tube corresponding to an impact energy of 5 Nm. After each impact the component is electrically tested, and no electrical breakthrough shall occur. Cross linkage: Several drops of methyl isobutyl ketone are put on a horizontal epoxy resin coated surface of the test piece at room temperature. After 30 seconds the test area is wiped with a clean white cloth. It is checked that the test surface has not become neither matt nor smeared, and that the cloth remains clean. The test is carried out 24 hours after the coating process. Adhesion: The adhesion of the powder coating on one of each type of component is tested at least four times a year using the punch separation method according to DIN 24624. The coating thickness over a dispersed area of the test item shall be within the range 250 μ to 400 μ. The test pieces are immersed for seven days in deionised water at 90ºC, and then dried in an oven for 3 hours. A conditioning phase of 3 to 5 days in normal atmosphere is then allowed to elapse. No blisters may arise during the period immersed in the water bath. 34 Valves and hydrants for fire protection

Technical appendix Corrosion protection and Rubber technology The surface of the test piece is degreased and then roughened with abrasive paper. The roughened surface is cleaned from dust with oil-free compressed air and recleaned. The adhesion on both the core and the moulding sand sides is tested with a minimum pulling force of >12 N/mm². Cathodic disbonding: Cathodic disbonding tests are carried out on one of each type of component at least twice a year. No bubbles in the coating may develop during the test for cathodic disbonding. For this test, the coating thickness over a dispersed area of the test item shall be within the range 250 μ to 400 μ. Approvals: The coating is approved for use in drinking water systems, meeting all specified toxicological conditions, by the following institutes: Hygiene Institute, Germany Hydrocheck, Belgium CARSO L.S.E.H.L., France Rubber technology: The high quality rubber used in the wedge has an excellent compression set also called memory(the ability to recover the original shape after being compressed). Even after many years of operation, tiny pebbles, sand and other impurities will not affect the rubber surface or the tightness of the valve. Unique AVK rubber compounds are applied to ensure that the wedge can absorbe the impurities in closed position and is able to regain its original shape when it is opened again. EN 681-1 A common European standard stating the minimum requirements for the physical properties. Compression set (permanent deformation). The rubber is deformed by 25 % of its original thickness at a constant temperature for a specific time. The pressure on the rubber is relieved and the layer thickness is measured after half an hour. The smaller the deformation, the better the memory effect. 20 % compression set 15 10 5 0 EN 681-1 AVK EPDM AVK NBR EN 681-1 AVK EPDM 23ºC, 72 hours, 25 % 70ºC, 72 hours, 25 % AVK NBR Valves and hydrants for fire protection 35
