Vacuum valves: Edwards (formely known as BOC Edwards) vacuum valves

Edwards IPVA10EK Solenoid Operation Air Admittance Valve

The IPVA10EK is a solenoid operated valve designed for automatic admittance of air or vent gas into a vacuum system. The valve has two ports with NW flanges. One of the valve ports is connected to the vacuum system, the other port can be left open to atmosphere or connected to a vent gas supply. The vacuum system is isolated from atmosphere (or the vent gas suppply) by a fluoroelastomer pad on the base of the valve plunger, which seals against the body of the valve.

Normally open and normally closed versions of the valve suitable for use with different electrical supplies are available to suit your application
