GM High Vacuum(Pressure)Diaphragm Valve

真空隔膜閥GM是型設(shè)計(jì)開發(fā)供接通或切斷真空系統(tǒng)之用的真空閥門。連接管焊接式真空隔膜閥更是溴化鋰制冷設(shè)備中的理想配件。高真空隔膜閥的適用介質(zhì)為空氣及非腐蝕性氣體。連接法蘭標(biāo)準(zhǔn)按GB6070或GB4982規(guī)定，也可為連接管焊接型式。

GM vacuum diaphragm valve is a vacuum valve designed and developed by Yongjia Keben Vacuum Valve Factory for connecting or cutting off the vacuum system. The connecting tube soldering vacuum diaphragm valve is an ideal accessory for lithium bromide refrigeration equipment. The suitable medium for high vacuum diaphragm valves is air and non corrosive gases. Connection flange standard according to GB6070 or GB4982, also can be connection pipe welding type.
