Product Summary

pdf

A Manual Vacuum Valve that forms a tight vacuum seal is disclosed. The valve incorporates a hollow, malleable, metallic O-ring that deforms and conforms readily under pressure to seal the space between a movable valve member and a valve seat. When the valve is closed, the O-ring is compressed between opposed machined surfaces of the valve member and the valve seat, readily deforming and conforming to those surfaces, thus creating a vacuum-tight seal thereat.

A Manual Vacuum Valve comprises: a housing having an inlet and an outlet; means defining a valve seat in the housing between the inlet and the outlet; and a valve seal assembly movable in the housing between an open position wherein the seal assembly is spaced from the valve seat allowing gas flow between the inlet and the outlet and a closed position wherein said assembly bears against said valve seat blocking said flow, said seal assembly including a valve member having inner and outer ends and being engaged to said housing so that when the valve member is rotated in one direction or the other, the seal assembly is moved toward its open or closed position; a hollow malleable metallic O-ring, and means for mounting said O-ring to the inner end of said valve member opposite the valve seat so that when the valve member is rotated to move the seal assembly to its closed position, the O-ring is compressively deformed between the valve seat and the mounting means creating a vacuum-tight seal between said inlet and said outlet.
