Abstract:
1. A wafer-style valve assembly adapted to be fixedly located relative to a centerline of a pipeline by a plurality of longitudinal fasteners, the valve assembly comprising: a substantially cylindrical valve body having a peripheral edge portion; a first centering clip disposed on the valve body and extending outward of the peripheral edge portion; and a second centering clip disposed on the valve body and extending outward of the peripheral edge portion, each of the first and second centering clips including a first arc-shaped edge bounded by a pair of first fingers and a second arc-shaped edge bounded by a pair of second fingers, each of the first and second centering clips further including a pair of recesses, each recess bounded by one of the first fingers and one of the second fingers; wherein the first and second centering clips comprise first and second plates removably securable to a common axial end surface of the valve body in a first configuration in which the first arc-shaped edge is disposed radially inward and a second and opposite configuration in which the second arc-shaped edge is disposed radially inward, such that the first and second plates are capable of accommodating a first pattern of longitudinal fasteners when disposed in the first configuration to locate the valve assembly relative to the centerline of the pipeline, and a second pattern of longitudinal fasteners when disposed in the second configuration to locate the valve assembly relative to the centerline of the pipeline, wherein the first pattern is distinct from the second pattern.
