直动式阀的动作较快, 因此, 这类装置可以用作削减压力峰值的经济型解决方案。
座阀型直动式阀具有低泄漏的结构条件, 并常常用来作为液压油缸油口的安全阀。
结构小, 低泄漏, 直动式阀用于导控制回路或限制负载传感泵的压力十分。
标准阀体采用铝或碳钢制作, 同时也提供多种密封材料选项。
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.
