GIQ型高真空氣動蝶閥 GIQ Pneumatic High Vacuum Butterfly Valve
GIQ型氣動高真空蝶閥是通過電磁換向閥改變氣路方向，控制執行氣缸驅動蝶閥作啟閉運動。高真空氣動蝶閥用于接通或切斷真空管路中的氣流。永嘉縣科本真空閥門廠生產的高真空氣動蝶閥適用介質為純凈空氣和非腐蝕性氣體。氣動高真空蝶閥可選配反饋信號裝置及電氣閥門定位器。
GIQ pneumatic high vacuum butterfly valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the butterfly valve opened and closed. It is used to put through or cut off the airflow in vacuum pileline. Applicable medium can be pure air and noncorrosive gases. They may be fitted with signal feedback device and electropneumatic valve positioner.
