GUD型電動高真空(壓力)球閥 Electromagnetism Vacuum air ball valve

GUD型電動高真空(壓力)球閥是以電動裝置驅動閥桿與球芯來執行啟閉動作，達到接通或切斷真空(壓力)系統管路中的介質流。永嘉縣科本真空閥門廠生產的GUD電動高真空壓力球閥應用于真空、乳制品、酒業、生物工程、食品、制藥、飲料、化妝品及化工領域。 

 GUD electric high vacuum(pressure) ball valves uses electric device to drive the stem and ball for open and close, thus to put through or cut off the medium flow in vacuum(pressure)pipeline. It is used in the areas of vacuum, dairy products, breweries, biological engineering, foddstuff, pharmaceuticals, drinks, cosmetics and chemicals.
