GM高真空壓力隔膜閥概述

GM High Vacuum(Pressure)Diaphragm Valve

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.
