Product Description
Overview
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 supply) by a fluoroelastomer pad on the base of the valve plunger, which seals against the body of the valve. 
The air or vent gas path through the valve is free from heavy metals.
*Voltage tolerance reduced at elevated ambient temperatures, maximum recommended ambient temperature: 40oC
**Normally open variants have an additional carbon loaded PTFE slide ring within the vacuum envelope
