Product Description

 

Overview of GM High vacuum pressure diaphragm valves

GM High Vacuum(Pressure)Diaphragm Valve
The GM is a vacuum valve designed for switching on or off the vacuum system. Connecting pipe welded vacuum diaphragm valve is the ideal accessories in lithium bromide refrigeration equipment. The applicable medium of high vacuum diaphragm valve is air and non-corrosive gas. The connection flange standard is specified by GB6070 or GB4982, and it can also be the welding type of the connection pipe.
