Abstract
A gate valve for controlling a flow of a fluid. The gate valve includes a valve body with a first seat pocket and a flow bore, a gate which is movable so as to intersect the flow bore, a seat with a gate end and a body end, a plate with an opening which is positionable on the seat at the gate end, and a plate retainer which is positionable between the seat and the plate so as to prevent an axial movement between the seat and the plate with respect to an axis of the flow bore. The flow bore extends through the valve body for the flow of the fluid. The gate end is arranged to face the gate, and the body end is positionable within the first seat pocket of the valve body.
