Abstract
A fluid control valve has at its lower inlet end a bi-loading seal. The seal is generally ring shaped in top view. However, it has a first flexible load section for sealing the stationary disk with respect to the housing and a second load section having an annular insert that in cross-section is hook-shaped to form a bend of more than 90 degrees. The insert can be molded within the resilient body of the seal so that its outer rim is disposed at a circular shoulder that bears against a seal stop of the housing. A high load can thus be applied between the bearing shoulder and seal stop to achieve a tight seal, while a lower load can be applied between the flexible, unrigidified part of the seal and a stationary valve disk.
