ABSTRACT:
A fluid sealing mechanism suitable for use in valves. This mechanism is capable of self aligning to ensure precise and repeatable sealing of the valve inlet to outlet. Sealing is accomplished by a plurality of standoffs on one surface which engage a plurality of corresponding grooves on another surface. Each standoff is independently adjustable in its height dimension in order to allow precise field adjustability of the sealing surfaces. This mechanism is suitable for use in pressure relief operations.
