- The Gruvlok® Series 7800 Check Valve is a compact, cost effective valve offering low pressure-drop, non-slam performance. The Series 7800 Check Valve assembly is lighter and faster to install, and costs less than flanged and wafer valve assemblies. In the fully open position the Series 7800 swing clapper is held tightly against the valve body, out of the flow stream, to provide maximum flow area and prevention of clapper flutter. The clapper design produces quick, non-slam closure before flow reversal can occur, while meeting FM requirements for an anti-water hammer valve rating. Each valve is hydrostatically tested for leak tightness to 500 psi. The clapper-seat design permits leak free sealing of back pressures in service conditions ranging from 300 psi (20.7 bar) to as low as 1 psi (0.07 bar) (head pressure: 28 in).
