Bottom valves

Product description:
These mechanically pilot-operated check valves are installed in multilevel cylinders.

Functional principle:
The hydraulic fluid flows via the integrated check valve towards the piston surface of the working cylinder. The valves operate as a backflow prevention device. Unlocking of the valve, i.e. the release of the second cylinder stage, happens fully automatically as soon as the first cylinder stage has been retracted.

P: pressure port
