Line: Vacuum Seal-off Valves

V1000 vacuum seal-off valves are simple, inexpensive, and reliable. Valve sizes range from 1/4″ through 3″ with matching operators. The V1000 vacuum seal-off valve provides an extra dimension to the vacuum system designer because it is compact, vacuum tight, and offers positive pressure relief. The basic weld on installation and simple operation will reduce installation and evacuation time, improving vacuum reliability and reducing product cost. An optional integrated port on the side of the 1/2″ and 1″ standard seal-off valves allows the installation of a vacuum sensor, eliminating the need for drilling
and welding on the system. Designed for use with vacuum-insulated piping systems, manifolds, flex lines, dewars, tanks,
chambers, furnaces, and any fabrication that requires a vacuum jacket.
