Counterbalance Valves


Counterbalance Valves

Parker counterbalance valves are screw-in type cartridge valves that control the pressure at an actuator controlling its motion. Uses include controlling over-running loads in cylinders and motors.


Parker’s vented load control valves are designed to operate independent of downstream pressure to prevent runaway loads under all dynamic conditions, handling pressures up to 350 bar (5000 psi) and flows up to 113 lpm (30 gpm).
