Pneumatic Ultra-high Vacuum Gate Valve
CCQ pneumatic ultra-high vacuum gate valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the valve disc up and down to make the valve opened or closed. It is used to put through or cut off the air passage in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases.
With signal feedback device.
