Pilot Operated Check Valve

Specializing in standard and custom high pressure valves for
water hydraulics and other high pressure water systems.

PILOT-OPERATED CHECK VALVES

FOR WATER, 95/5, OIL OR OTHER LIQUIDS

The Valv-Trol Pilot Operated Check Valve is based on standard components, but optimized for individual applications. The port connections, pilot actuators, and pressure ratings 2,000 PSI /138 Bar standard) can be specified to best handle the operating conditions.
They are also used as prefill or dump valves for large hydraulic presses or cylinders. A small integral de-compression valve can be specified to bleed off the high pressure before the main valve opens. This can help reduce the shock of opening a large valve under high pressure..
The operation of this valve is very similar to a standard spring loaded check valve, but with one important difference: The pilot cylinder can, when actuated, hold the valve open so that fluid may flow freely in either direction. When the pilot pressure is removed, the flow in one direction is stopped just as in a check valve
