Abstract
Embodiments of the invention provide a housing assembly for a knife gate valve. The housing assembly includes a valve body defining a passageway and having a first body and a second body, and a one-piece liner arranged between the first body and the second body. The first body and the second body each include a flange recessed portion that defines a flange recess surface. Each of the flange recess surfaces includes a first flange surface portion, a second flange surface portion, and a raised flange bead. The one-piece liner includes a first liner flange portion that forms a first liner recess. The first liner recess receives the flange recessed portion of the first body to bring the raised flange bead of the first body into engagement with the first liner flanged portion.
