Pressure Sustaining

The Cla-Val Pressure Sustaining / Relief Valves are hydraulically operated, pilot-controlled, modulating valve designed to maintain constant upstream pressure within close limits. This valve can be used for pressure relief, pressure sustaining, back pressure, or unloading functions in a by-pass system. Other combinations are list below
