Piloted hydraulic block valves, also known as piloted check valves, are a kind of one-way valve in which the normally closed passage can be opened by the action of a pilot pressure.

The opening of the sealing system by the pilot pressure is on/off (from fully closed to fully open).

These hydraulic valves are particularly suitable for installation on hydraulic cylinders for load retention. Mainly used on double-acting cylinders where they receive pilot pressure from the return line.

Available in the following versions:

- single-acting piloted check valve with BSP thread;

- single-acting piloted check valve with DIN2353 version (for 10L, 12L or 15L pipe);

- BSP double-acting piloted check valve;

- double-acting piloted check valve DIN2353 (for 10L, 12L and 15L pipe);

- double-acting pilot-operated check valve with in-line mounting;

- inline single-acting piloted check valve;

- pilot-operated check valve with mounting on double-acting cylinder boss DIN2353 or BSP connection.

 

To complete the range, tubes, also known as eye connectors, are available in different lengths, and corresponding drilled screws.
