Pilot Operated Check Valve
Specializing in standard and custom high pressure valves for
water hydraulics and other high pressure water systems.
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
