Product Description of VCR Pneumatic diaphragm valves
VCR diaphragm valves may have a maximum working pressure of 100 psig (6.9 bar) for vacuum applications
VCR diaphragm valves may have a maximum working pressure of 150 psig (10.3 bar) for gas and liquid applications
(Choose the right type of diaphragm valve for your needs)
Features of Stainless steel Pneumatic diaphragm valves
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
