今天，主要介紹產品類型廣泛以及在中國使用以及比較多的品牌美國威盾VTON
VS4F10FPF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。用于接通或切斷真空管路中的氣流。適用介質為純凈空氣和非腐蝕性氣體。可選配反饋信號裝置及電氣閥門定位器。
VS4F10FPF 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.
