Cla-Val - Hydraulic Pressure Control Valves - 50-33 & 650-33 Back Pressure Shutoff Safety Valve with Manual Reset ***
The 50 Series Pressure Relief Valve is designed to maintain constant upstream pressure within close limits. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. In addition to surge relief, this valve can be used for pressure relief, pressure sustaining, back pressure or unloading functions in a by-pass system.
Cla-Val 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.
