Double unlockable check valve (blocking block) with pipe connection

Load-holding valves (or lowering brake valves) are offered here for double-acting hydraulic cylinders (or double-acting hydraulic functions).

The load-holding valve is used to securely hold hydraulic cylinders or comparable double-acting functions without leakage.

The special advantage of load-holding valves, especially compared with double-pilot operated check valves, is their much more sensitive opening behavior.
They can also generate back pressure with pulling loads, allowing the loads to be controlled more sensitively.

This valve is also pressure compensated, which means that the upstream valve does not need to be relieved for this valve to shut off reliably.
