Inline Pilot Check Valve Stabiliser Leg 320bar 4800 Psi

In stock
Product Details

This sale is for a Dual or Single inline pilot check valve. These are widely used for stabilizer legs, cranes & any other hydraulic use where it is essential a function does not drop if hydraulic power is lost ie. broken hose or fitting.

These 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 which can be opened by an external pilot pressure.

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

Dual P.O.checks are often used to positively lock a dual acting cylinder.

Watch the video below if you want to see and learn how to install a double pilot check valve to a hydraulic cylinder. Complete DIY Kits available for your existing cylinders just email us with your port thread and size and port center dimension and we will quote you up a kit.

Single inline pilot check valves are also available in drop box. They are the same price. Please leave message if required !

These are quality items made in Italy..
