CF高真空擋板閥系列 Pneumatic High Vacuum Flapper Valve

CF高真空擋板閥系列是通過電磁換向閥改變氣路方向，控制執行氣缸驅動閥門作啟閉運動。CF高真空擋板閥系列用于接通或切斷真空管路中的氣流。CF高真空擋板閥系列適用介質為純凈空氣和非腐蝕性氣體。CF高真空擋板閥系列帶反饋信號裝置。

CF 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.
