Counterbalance valve

Some actuators with running-away (or overrunning) loads will let the load free fall when the directional valve that controls the actuator shifts to lower the load. Cylinders with large platens and tooling or hydraulic motors on winch drives are two examples of such actuators. Both counterbalance valves and pilot-operated check valves can be used to lock fluid in a cylinder to prevent drifting.

However, a pilot-operated check valve cannot control an over-running load. Whenever uncontrolled movement can occur from an overrunning loa a counterbalance valve should be used.

Counterbalance valves are used in hydraulic systems working with overriding (running-away) or suspended load.
