SWING CHECK VALVE STANDARD & "SHOTGUN" MODEL RCV FIRE SPRINKLER CORPORATION GROOVE/GROOVE DESCRIPTION AND OPERATION 2", 2 Y2'vrt 3 rr 4" & 61`1 SIZES Globe Model RCV Swing Check Valves feature a swing type clapper designed for use in fire sprinkler or other types of water piping systems that incorporate grooved connecting pipe ends. They are effectively used when it is necessary to permit water flow in one direction only, preventing flow in the reverse direction (non- return). Because the RCV incorporates a spring-loaded clapper assembly, it may be installed in either the vertical or horizontal position. Most commonly, it is used with various configurations of fire department connections for fire sprinkler systems, by-pass connections,gravity pressure tank and, pump discharge in connec- tions from public water supplies to automatic sprinkler systems,etc. As an alternative to using an alarm check valve with a wet sprinkler system, an RCV Swing Check Valve may be used in a "Shotgun" arrangement whereby the valve is trimmed in a similar manner but utilizes an electric water flow switch and alarm bell instead of a water motor gong for fire notification. The body of the Globe RCV Swing Check Valve is constructed MODEL RCV of high tensile strength cast iron having considerable ductility to SWING CHECK VALVE reduce damage in field handling. It meets the ASTM A126 Class B rating. The RCV clapper assembly is made of stainless steel and has an E.P.D.M. rubber facing. The RCV incorporates a special stainless steel spring assembly which allows its use in the down- ward flow direction. It effectively provides a leak tight seal against back pressures greater than one (1) psi. PHYSICAL DIMENSIONS APPROVALS • cULus Listed "H' ® FM Approved OPTIONAL FOR RISER O .
