高真空氣動(dòng)擋板閥在真空系統(tǒng)中作切斷或接通氣流之用。 永嘉縣科本真空閥門廠的高真空氣動(dòng)擋板閥以壓縮空氣為動(dòng)力，通過控制氣動(dòng)元件來改變氣路方向，執(zhí)行氣缸驅(qū)動(dòng)使擋板閥做啟閉運(yùn)動(dòng)。 氣動(dòng)高真空擋板閥適用的工作介質(zhì)為空氣及非腐蝕性氣性。
氣動(dòng)高真空擋板閥 Pneumatic High Vacuum Flapper Valve
GDQ型氣動(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)。GDQ-J/S型高真空氣動(dòng)擋板閥用于接通或切斷真空管路中的氣流。GDQ-J/S型高真空氣動(dòng)擋板閥適用介質(zhì)為純凈空氣和非腐蝕性氣體。GDQ-J/S型高真空氣動(dòng)擋板閥帶反饋信號(hào)裝置。
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.
