Check Valve 815b February 16,2007 \lIKlNGi@ TECHNICAL DATA EASY RISER@ SWING CHECK VALVE MODELS E-1 & F-1 J . Refer to technical data pages 47 a-c - Automatic Pressure Control System Material Standards: Refer to Figure 1 4. INSTAllATION FOR THE VIKING ESFR COLD STORAGE SYSTEM, REFER TO DATA PAGE 45 a-j FOR INSTRUCTIONS ON PLACING THE SYSTEM IN SERVICE. The Easy Risef'1ll Swing Check Valve must be installed in an area not subject to freezing temperatures or physical damage. When corrosive atmospheres and/or contaminated water supplies are present, it is the owner's responsibility to verify compatibility with the Easy Risef'1ll Swing Check Valve, trim, and associated equipment. Prior to installing the valve, thoroughly flush the water supply piping to verify that no foreign matter is present. The Easy Risef'1ll Swing Check Valve may be installed in the vertical position with direction of flow up, or in the horizontal position with the access cover up. 1. Remove all plastic thread protectors from the openings of the Easy Risef'1ll Swing Check Valve. 2. Apply a small amount of pipe-joint compound or tape to the external threads of all pipe connections required. Take care not to allow any compound, tape, or other foreign matter inside any of the nipples or openings of the valve or trim components, 3, Easy Risef'1ll Swing Check Valve Trim Charts are provided with Trim Packages and in the Viking Engineering and Design Data book. 4. Verify that all system components are rated for the water working pressure of the system, Hydrostatic Test: The Easy Risef'1ll Swing Check Valve is manufactured and listed for use at a maximum water working pressure of 250 psi (17 .2bar). The valve is factory tested at 500 psi (34,5 bar), Easy Riser@) Swing Check Valves may be hydrostatically tested at 300 psi (20,7 bar) and/or 50 psi (3,5 bar) above the normal water working pressure for limited periods of time (two hours) for the purpose of ac- ceptance by the Authority Having Jurisdiction, If air testing is required, do not exceed 40 psi (2,8 bar) air pressure, 5. OPERATION (Refer to Figure 1) Water flowing through the Viking Easy Risef'1ll Swing Check Valve lifts rubber-gasketed clapper (8 and 9) off the seat (12) and flows into the sprinkler piping. When flow through the valve stops, the clapper (8) closes quickly. Rubber gasket (9) forms a tight seal against brass water seat (12), trapping pressurized water above the clapper and preventing reverse flow from the sprinkler piping 6. INSPECTIONS, TESTS AND MAINTENANCE FOR THE VIKING ESFR COLD STORAGE SYSTEM, REFER TO DATA PAGE 45 a-j FOR INSPECTIONS AND TESTS NOTICE: THE OWNER IS RESPONSIBLE FOR MAINTAINING THE FIRE-PROTECTION SYSTEM AND DEVICES IN PROPER OPERATING CONDITION, The Viking Easy Risef'1ll Swing Check Valve and trim must be kept free of foreign matter, freezing conditions, corrosive atmos- pheres, contaminated water supplies, and any condition that could impair its operation or damage the device. It is imperative that the system be inspected and tested on a regular basis. The frequency of the inspections may vary due to contaminated water supplies, corrosive water supplies, and corrosive atmospheres. For minimum maintenance and inspection requirements, refer to NFPA 25. In addition, the Authority Having Jurisdiction may have additional maintenance, testing, and in- spection requirements that must be followed. WARNING: ANY SYSTEM MAINTENANCE WHICH INVOLVES PLACING A CONTROL VALVE OR DETECTION SYSTEM OUT OF SERVICE MAY ELIMINATE THE FIRE-PROTECTION CAPABILITIES OF THAT SYSTEM. PRIOR TO PROCEEDING, NO- TIFY ALL THE AUTHORITY HAVING JURISDICTION. CONSIDERATION SHOULD BE GIVEN TO EMPLOYMENT OF A FIRE PATROL IN THE AFFECTED AREAS. 6-A. Five-Year Internal Inspection Internal inspection of check valves is recommended every five years unless inspections and tests indicate more frequent inspections are required, (Refer to Figure 1) 1. Notify the Authority Having Jurisdiction, remote station alarm monitors, and those in the area affected that the system will be taken out of service, Consideration should be given to employment of a fire patrol in the affected areas. 2. Close the water supply main control valve, placing the system out of service, 3, Open the main drain. If necessary, open the system test valve to vent and completely drain the system. 4. Use the appropriate wrench to loosen and remove cover screws (14), and remove cover/clapper assembly (2-11),
