COUNTERBALANCE SANDWICH VALVE Series CB

Series CB Counterbalance valve controls the actuator movement with overrunning loads.
The return flow from the actuator is piloted and controlled by the inlet flow to the actuator, ensuring a cavitation-free lowering load.                                                                       
The counterbalance valve operates as a pressure relief valve. The setting pressure is lowered by the pressure in the inlet line. To ensure safe load holding the setting pressure should be approximately 30% higher than the maximum load pressure.
