■ 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.
