Leg cylinder check valves

Product description:
These check valves are used to extend or retract leg cylinders or hold them in position.

Functional principle:
The hydraulic fluid flows from P to A via the integrated check valve. The valve locks any unwanted reverse flow of the fluid. The check valve is hydraulically opened via port Z, enabling the flow from A to P.

P: pressure port
A: actuator port
Z: control pressure
