Pilot-operated 3-way vacuum valves
These 2-position, 3-way valves feature pneumatically activated conical
sutters. They can be normally used either open or closed.
They are recommended in all the cases that require a quick exchange between the vacuum pump suction and the air inlet into the circuit for a
quick restoration of the atmospheric pressure. They are composed of an anodised aluminium body, two vulkollan® shutters assembled onto a stainless steel stem, a membrane for servo-control made with special compounds and a thrust spring for the shutter return. These valves allow reducing frictions and internal dynamic stresses to the minimum, the result being a high response speed and a guarantee of long lasting duration. Technical features Working pressure: from 0.5 to 3000 mbar abs.
Servo-control pressure: see table Temperature of the sucked fluid: from -5 to +60 °C
