Sun Hydraulics Counterbalance Cartridge Valves

Precise Load Holding | Overrunning Load Control | Enhanced Safety

Sun Hydraulics’ Counterbalance Cartridge Valves are engineered to control and stabilize overrunning loads in hydraulic systems. These valves maintain a controlled back pressure to prevent unintended actuator movement or load runaway, ensuring smooth, safe, and reliable operation in lifting, lowering, and holding applications.

Designed as compact screw-in cartridges compatible with standard ISO cavities, Sun’s counterbalance valves offer superior performance with minimal leakage and fast response. Available in various configurations, including direct-acting and pilot-operated types, they provide versatile solutions for demanding industrial, mobile, marine, and offshore hydraulics.
