Cla-Val - Hydraulic Pilots & Accessories - CRL & 55F Pressure Relief Valve ***
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.
The Cla-Val Model CRL and 55F Pressure Relief Valves are direct-acting, spring-loaded, diaphragm type relief valves. Often used as pilot controls for Cla-Val Hytrol valves, they can also be used as self-contained pressure relief valves. These valves may be installed in any position and open and close within very close pressure limits.
