Vacuum Valves V2000 Series Seal-off Valve

Spring-loaded Valve for Evacuation Entry Into Any Large Vacuum System

The V2000 vacuum seal-off valve is a high conductance, compact and highly reliable means of providing an evacuation entry into any large 2″ vacuum system including cryogenic tanks, dewars, vacuum-insulated piping and MRI magnet vacuum containers. The valve incorporates a spring-loaded poppet which provides relief in the event of an overpressure, protecting an inner vessel or neck seal. The poppet and spring assembly is installed after the body is welded to the vacuum space.
The V2000 is used with a valve operator to connect to a vacuum pump and is removed after the evacuation process is finished. The valve operator stem engages the poppet and the handle is toggled up to pull the poppet open and begin the evacuation. After the evacuation is complete, the handle is toggled down and the poppet re-seats providing a vacuum tight seal. The stem is then disengaged from the poppet and the valve operator is removed to complete the operation.
