Features of Manual Operated Diaphragm Valve

1.Metal to metal sealing provides leak free service from vacuum to high pressure

2.The internal volume is small, and the flow channel can be completely purged

3.Fully wrapped valve seat design, with superior anti expansion and anti pollution ability
4.Nickel cobalt alloy diaphragm has higher durability and corrosion resistance
5.The standard roughness is Ra0 twenty-five μ M (grade BA), or electropolishing Ra0 thirteen μ M (EP grade) optional

6.Helium test leakage rate ＜1 × 10-9 std cm3/s
7.Pneumatic actuators are available
8.The service life of pneumatic valve can reach 3 million times
