General Application High Pressure Pneumatic Diaphragm Valve
High-pressure diaphragm valves are designed for semiconductor, solar photovoltaic, laboratory and other applications that need to lay gas pipeline systems. The diaphragm valve is suitable for the application of high purity gas and provides on/off function. The maximum working pressure of the high-pressure diaphragm valve is 3000psi(206bar).

good quality Diaphragm valves 100% passed helium leak detection test and function test before leaving the factory.
