直動式閥的動作較快, 因此, 這類裝置可以用作削減壓力峰值的經(jīng)濟型解決方案。
座閥型直動式閥具有低泄漏的結構條件, 并常常用來作為液壓油缸油口的安全閥。
結構小, 低泄漏, 直動式閥用于導控制回路或限制負載傳感泵的壓力十分。
標準閥體采用鋁或碳鋼制作, 同時也提供多種密封材料選項。
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 approximay 30% higher than the maximum load pressure.
