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。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 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. ■ 主要技術性能 Main Technical Performance ■ ■ ■ 　閥門漏率：Valve Leak Rate 　≤1.3×10-4Pa.L/S. 　適用溫度：Applicable Temperature 　-30～+150℃ 　-30～+150℃(PPL密封) 　關閉時間：Close time 　≤30S 　適用范圍：Applicability 　連接型式　Loose Flange 　使用壓力范圍(Pa) 　活套法蘭(GB6070、JB919) 　0.6×106～1.3×10-4 　焊接法蘭(GB6070、JB919) 　1.6×106～1.3×10-4 　快卸法蘭(GB4982) 　0.1×106～1.3×10-4 　螺紋連接　Threaded Connection 　1.6×106～1.3×10-4 ■ 主要零件材料 Materials of Main Parts ■ ■ 閥體、閥蓋、閥桿：不銹鋼 密封件：四氟乙烯、氟橡膠、PPL。 Body, disc and stem: stainless steel.
