GDQ氣動(dòng)高真空擋板閥概述

GDQ氣動(dòng)高真空擋板閥是通過電磁換向閥改變氣路方向，控制執(zhí)行氣缸驅(qū)動(dòng)閥門作啟閉運(yùn)動(dòng)。用于接通或切斷真空管路中的氣流。適用介質(zhì)為純凈空氣和非腐蝕性氣體。帶反饋信號(hào)裝置。

GDQ Pneumatic High Vacuum Flapper Valve

GDQ 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.
