Accu-Glass Pressure Relief Valve, CF 2.75, Factory Set to 2.0 psi, Adjustable 0.50-2.0 psi PN: 113150 This Pressure Relief Valve (PRV) from Accu-Glass is mounted on a CF 2.75 flange. Factory setting is at 2.0 psi, but with its' precise pressure adjustment can be set as low as 0.50psi. This PRV is suitable for High vacuum processes down to 1x10-8 Torr (leak tested to 5x10-10 Standard cc/sec of He), and has a temperature rating up to 150° C. Vacuum systems are only designed to operate under external (atmospheric) pressure. A Pressure Relief Valve offers a means of protecting vacuum vessels against internal over-pressurization. There are many scenarios in which rapid pressure buildup inside a vacuum vessel may occur — such as a runaway gas back-fill operation. Besides protecting delicate instruments and equipment, A Pressure Relief Valve also minimizes the risk of injury to system operators and other lab personnel.

Edwards IPVA10EK Air Admittance Vent Valve, NW-KF10, 110VAC, Normally Closed, NC, Aluminum, PN: C41732000 The Edwards IPVA10EK is a solenoid operated vent valve designed for automatic admittance of air or vent gas into a vacuum system. The valve has two ports with KF 10, NW 10 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. This is a normally closed version of the valve suitable for use with 110 VAC to suit your application. These Edwards IPVA10EK 110VAC air admittance vent valves have a KF10 vacuum flange and are sold as one each.
