Water relief valve Liquiflo

Positive Displacement (PD) pumps should always be installed with a Relief Valve in the discharge line, to protect the pump and piping against any type of line blockage, including the inadvertent closing of an isolation valve. Liquiflo manufactures two sizes of relief valves in both 316 Stainless Steel and Alloy-C.

Ten standard Liquiflo Relief Valve models are available, based on the body material, the port size, and the pressure setting range (see chart below). Models RV1000, RV1001, RV2000 and RV2001 are factory preset to discharge at 100 PSI (7 bar) unless a different pressure setting is requested when ordering; other models are preset to the pressure setting specified when ordering.
