Twin pilot-operated check valves

Product description:
These twin pilot controlled check valves are used to extend or retract cylinders or hold them in position. They are mainly used for front cantilever cylinders.

Functional principle:
The hydraulic fluid flows from P to A and B via the integrated check valves.
The valves lock any unwanted reverse flow of the fluid. Both check valves are hydraulically opened via port Z, allowing the hydraulic fluid to flow from A and B to P.

P: pressure port
A and B: actuator ports
Z: control pressure
