直動(dòng)式閥的動(dòng)作較快, 因此, 這類裝置可以用作削減壓力峰值的經(jīng)濟(jì)型解決方案。
座閥型直動(dòng)式閥具有低泄漏的結(jié)構(gòu)條件, 并常常用來(lái)作為液壓油缸油口的安全閥。
結(jié)構(gòu)小, 低泄漏, 直動(dòng)式閥用于導(dǎo)控制回路或限制負(fù)載傳感泵的壓力十分。
標(biāo)準(zhǔn)閥體采用鋁或碳鋼制作, 同時(shí)也提供多種密封材料選項(xiàng)。
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.
