The machine is equipped with a hydraulic switch valve to ensure safety during loading and unloading workpieces 工作台起动有液压开关阀,确保装卸工件时的安全性。
This valve uses the principle of two - stage pressure reducing variation and , when to lower the switch valve , the shock from the water pressure to the valve casing shortens the start time of this valve under the highest medium pressure and makes it with the incomparable superiority of energy saving among the pulse - type electric - controlled valves 该阀采用二级减压变化原理,降低开关阀时水压对阀体等配件的冲击,提高电磁阀的可靠性和工作寿命,缩短了阀在最高介质压力下开启时间,使其在脉冲式电控阀门中具有无可伦比的节能优势。
