High efficiency cryogenic connection for vacuum insulated piping systems. Close design tolerances eliminate the necessity of a nose seal.
An integrated port added to a 1/2″ and 1″ standard seal off valves allows a vacuum sensor to be installed without drilling and welding, saving time and eliminating potential leak paths.
An evacuation valve which is compact, vacuum tight, has excellent capacitance and offers positive pressure relief. Simple, inexpensive and reliable, this design ranges in size from 1/4″ through 3″ with matching operators.
