Double Overcenter Valve Hydraulic Fitting Counterbalance Valve
The principle of operation of a counterbalance valve involves the internal pilot valve and main spool working in tandem.
In forward flow, oil is allowed to flow freely into the cylinder to lift the load; in reverse flow, the main spool closes to keep the load stationary unless the pressure at the control port reaches a set relief value.
