Abstract:
1. A valve comprising: a housing, the housing comprising a fluid inlet, a fluid outlet, and an annular seat retainer, the annular seat retainer comprising an annular planar shelf that faces toward one the fluid outlet and the fluid inlet and away from the other of the fluid outlet and the fluid inlet; an anular housing seat, the housing seat comprising an annular planar shelf that faces toward the shelf of the annular seat retainer and is spaced therefrom, the housing seat being fixed in position relative to the housing via epoxy with the epoxy extending between the shelf of the annular seat retainer and the shelf of the housing seat, at least one epoxy port extending through the housing seat for injecting the epoxy; and a gate comprising a gate seat and a fluid passageway that extends through the gate, the gate being movable relative to the housing between an open position and a closed position, the gate being configured to allow fluid to flow from the fluid inlet through the fluid passageway to the fluid outlet when the gate is in the open position, the gate being configured such that the gate seat engages the housing seat in a manner preventing fluid from flowing from the fluid inlet to the fluid outlet when the gate is in the closed position, contact force acting on the housing seat as a result of the gate seat engaging the housing seat being borne by compression of the epoxy between the shelf of the annular seat retainer and the shelf of the housing seat.
