Abstract
A plug valve having a body with an inlet, an outlet and a plug-receiving opening which intersects the inlet and outlet. A plug is mounted in the opening and has an outer wall and an orifice extending therethrough. The plug is movable from an operative position in which the orifice connects the inlet to the outlet to allow fluid to flow to an inoperative position in which the orifice is disconnected from the inlet and outlet to prevent the flow of fluid from the inlet to the outlet. The plug outer wall has a seal-receiving portion which is spaced from the orifice and which is adapted to removably receive a seal retainer assembly. A seal is interposed between the seal-receiving portion of the plug and at least a portion of the seal retainer assembly to form a seal.
