This Pfeiffer Stainless Steel Pressure Relief Valve protects vacuum systems from over pressure. It has KF-16 fittings on both the inlet and outlet ends. An exhaust hose can be attached to the KF16 connection at the outlet side. Measuring just 30mm in diameter and 25mm in height, this compact Pfeiffer Pressure Relief Valve has a leak rate of less than 1 x 10-8 mbar l/s, a temperature range from 41-140°F (5-60° C), and opens with a pressure differential of approximately 300 Torr. It is intended to be used for vacuum chambers only.

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.

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.

Vent Valves are typically used to introduce air in to the vacuum chamber and bring the system up to atmospheric pressure. These vent valves can be used to fill the vacuum chamber with room air or a N2 gas supply can be plumbed to the 1/4 O.D. tube side of the valve. These vent valves have a NW-16 vacuum flange for connection to the vacuum system, are manually operated, and made of stainless steal.

NW40 KF40 Viton Centering Ring - STAINLESS STEEL The MKS Series 225 Auto-Soft is a flow actuated check valve used for throttling roughing pumps during initial evacuation. Auto-Soft closes very quickly at the start of system evacuation and opens automatically upon reaching a set pressure differential. This leaves the pumping line open for the balance of the pumping process. This is a simple NW KF Valve fitting for automatic soft starts. The Auto-Soft valve has a vane that pivots about an off-center axis. A pair of coil springs hold the vane open when the pressure differential is low enough. When the roughing system goes into operation, the initial flow closes the vane assembly, automatically throttling the roughing pump. Initial pumpdown occurs through small openings around the vane. This reduces the effective pumping speed, which minimizes turbulence and extends pumpdown time. When the pressure differential reaches the level determined by the springs, the springs open the vane and full pumping speed is restored.
