        氣動高真空直通式擋板閥

        GDQ-Y型氣動高真空直通式擋板閥 Pneumatic High Vacuum Flapper Valve

        GDQ-Y型氣動高真空直能式擋板閥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。GDQ-J/S型高真空氣動擋板閥用于接通或切斷真空管路中的氣流。GDQ-J/S型高真空氣動擋板閥適用介質為純凈空氣和非腐蝕性氣體。GDQ-Y型氣動高真空直通式擋板閥可帶反饋信號裝置。 

        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.
