Cla-Val - Hydraulic Pressure Control Valves - 52-03 & 652-03 Pressure Relief & Surge Anticipator 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.
Cla-Val Models 52-03 and 652-03 Surge Anticipator Valves are indispensable for protecting pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by rapid changes of flow velocity within a pipeline.
When using these valves, pumping systems are started and stopped gradually preventing harmful surges from occurring.
