320bar Hydraulic Valve Cast Steel Counterbalance Valve for Crane
Single counterbalance valves are specially designed hydraulic control valves that combine the functions of check valves and relief valves, and are mainly used in hydraulic systems to keep the load moving steadily.
The single counterbalance valve enables the speed of movement of hydraulic motors and cylinders to remain stable independent of load changes. It also has good sealing properties and prevents accidents by preventing the free fall of heavy loads in the event of pipeline damage or brake failure.
In addition, it is able to provide smooth and adjustable motion under different operating conditions, such as preventing the load from dropping suddenly when the pipeline or hose is damaged, and providing smooth motion when the load is at low pressure or out of control.
