Application

High vacuum bellow valve in action

Bellow sealed angle valve VE, stainless steel, KF DN 16

High vacuum, helium leak-tested right angle valves VE have stainless steel bellows which seals the drive mechanism without any gap on the vacuum side. Due to the screw-thread mechanism, these valves offer a certain control of conductance. They are mountable in any position because of their air tightness in both positions. The body is either made of solid aluminum or stainless steel (VE WIG). The stainless steel valves are tungsten inert gas welded from the inside for maximum gas tightness and minimum degassing rates.
