電動真空球閥是以電動裝置驅(qū)動閥桿與球芯來執(zhí)行啟閉動作，達到接通或切斷真空(壓力)系統(tǒng)管路中的介質(zhì)流。應(yīng)用于真空、乳制品、酒業(yè)、生物工程、食品、制藥、飲料、化妝品及化工領(lǐng)域。

■ GUD
Electromagnetism Vacuum air valve

■ GUD electric high vacuum(pressure)ball valve 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.
