摘要:
A wafer-style valve assembly adapted to be coupled between opposing pipeline components having a common centerline secured together by a plurality of longitudinal fasteners includes a substantially cylindrical valve body, a seat retaining plate, and at least one clip. The valve body has a peripheral edge portion and an axial end surface. The seat retaining plate is disposed on the axial end surface. The at least one clip is also disposed on the axial end surface and extends radially outward of the peripheral edge portion. The clip has a radially inward portion and a radially outward portion. The radially inward portion secures the seat retaining plate to the to valve body. The radially outward portion has an edge defining a first recess and a second recess. The first and second recesses are each adapted to accommodate a longitudinal fastener to locate the valve assembly relative to the centerline of the pipeline.
