Today we will be talking about Hydraulic Check Valves

A pilot operated check valve allows free flow from it’s inlet port to its outlet

port just as ordinary check valve.

fluid flow attempting to pass through the valve from outlet to inlet port will

force the popped on its seat. Flow through the valve is blocked

when enough pilot pressure is sensed at the plunger piston, the plunger is removed

and in seals the check valve poppet. Flow can pass through the valve from outlet to

inlet as long as suffice pilot pressure is acting on the plunger piston,as soon in illustration.

We always welcome any questions or comments on this subject or any other other subject.
