Double unlockable check valve (blocking block) with pipe connection

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

The load holding valve is used for leakage-free and secure holding of hydraulic cylinders or comparable double-acting functions. The valve also has a pressure relief function and opens when the set value is exceeded.

The particular advantage of load holding valves compared to double-unlocking check valves lies in the significantly more sensitive opening behavior.
In addition, they can generate a counterpressure 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 close securely.
