Pneumatic high vacuum isolation valve- large sizes
Unique Vacuum    Unique Vacuum
Pneumatic high vacuum damper valve, motivated by compressed air, pushes the cylinder to up and down move with the valve rod by changing the direction of electromagnetism to transform the gas circuit direction, which drives the valve to open or close, in order to cut off or connect gas flow in the vacuum system. J is angle type and J(S) is three-way type with pre pumping. Applicable medium can be air and noncorrosive gases.
