Vacuum Evacuation Valves
Eden Cryogenic vacuum evacuation valves are engineered and designed to provide a safe, reliable method of vacuum closure. Fabricated from 304/304L these valves will withstand the most severe outdoor applications. All Eden Cryogenic evacuation valves meet code requirements for over-pressure relief in a vacuum jacketed system.
All of Eden’s evacuation valves are designed to relieve at approximately 15 psig and are supplied with protective covers to prevent contamination from dirt or moisture. Each design utilizes dual fluorocarbon rubber o-rings and is tested to seal leak tight when mass spectrometer leak tested at 1 x 10-10 scc/sec helium. Removable evacuation valve operators exist for each size and configuration allowing easy connection to vacuum pumping devices and insuring a positive static seal upon final evacuation.
