50-33 & 650-33 Pressure Relief Valves

(50-33 & 650-33)
Cla-Val Pacific's 50-33 and 650-33 Excess Pressure Safety Shut-Off Valves (XPSV) automatically protect the downstream distribution piping and fixtures from experiencing excess unsafe pressures in the event that outlet pressure of the high flow PRV rises above an acceptable level.
