科恩科KNKE氣動真空擋板閥，Pneumatic vacuum flapper valve，也叫氣動角閥，是用壓縮空氣為動力，通過電磁換向閥改變氣路方向，推動氣缸活塞上下運動，帶動閥桿上下運動，使閥板開啟或關閉，從而達到在真空系統中接通或切斷氣流的目的。K-GDQ-J型為角通型式，K-GDQ-S型為帶預抽口的三通型式。適用的工作介質為空氣及非腐蝕性氣體。
注：其中DN400以上底部采用死法蘭n-Mb。

Pneumatic High Vacuum Flapper Valve

pneumatic high vacuum flapper valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the valve opened and closed. It is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases.

With signal feedback device.
