Product Description

Counterbalance valves with pilot assist are meant to control an overrunning load. Normally used in conjunction with a 3 position directional control valve, the counterbalance valve allows free flow in one direction but prevents return flow until pilot pressure is admitted. The external force is sustained until the pilot pressure moves the spring loaded valve spool and allows metered flow back to the tank. A second function provides a shock absorbing overload relief. Excellent metering characteristics are provided by the tapering spool and, when seated, leakage does not exceed 10cc/min at 315 bar.
