■ GUD型电动高真空(压力)
球阀是以电动装置驱动阀杆与球芯来执行启闭动作，达到接通或切断真空(压力)系统管路中的介质流。应用于真空、乳制品、酒业、生物工程、食品、制药、饮料、化妆品及化工领域。
■ 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.
