How a Pilot Check Valve Works to Hold a Load on a Hydraulic Ram

Pilot Check Valves are widely used for stabilizer legs and leveling of mobile plant, Cranes, MHydraulic Ram, or Cylinder does not drop or move if hydraulic power is lost or a hydraulic hose or fitting comes loose or fails.

Pilot Check valves are a mandatory safety item for many hydraulic applications. Dual Pilot operated check valves (also referred to as P.O. check valves), are check valves that can only be opened by an external pilot pressure signal.

Thus, P.O. checks, block flow in one direction, like standard check valves, but can be released once adequate pilot pressure is applied.

To Pass many Safety inspections Pilot Check Valves need to be hard-plumbed into a cylinder. That is they can not be connected to a cylinder with hoses but must be connected with more durable, stronger, and longer life Steel pipework and solid adaptors.

So if the piston seal is leaking can that pilot the check valve to open causing cylinder drift? I put a gauge on the pilot line to the valve from the rod side . With a load on the cylinder, the pressure in the pilot line slowly increases until it reaches 500psi then the cylinder starts drifting..

Can I use that valve to connect my hidraulic cylinder (oil) with air compressor directly ? Thanks 🙏
