Gresen Lock Valve

Lock valve models LO and LOA  are designed to lock a cylinder, or part of a circuit, without leakage while a control valve is in a neutral position. Lock Valves function as check valves, allowing flow to cylinder and blocking reverse flow until pilot pressure is applied to “unlock” the circuit.

These valves may be used as safety devices to prevent movement of a load while pressure source is inactive and control valve is accidentally operated.

Designed for applications where fluid leakage through control valve could adversely affect the performance of the system such as clamps, outriggers and work platforms.
