SEAL RETAINER/LONGITUDINAL CENTERING CLIPS WITH MULTIPLE FLANGE CAPABILITY

摘要

A wafer-style valve assembly (10) adapted to be coupled between
opposing pipeline components having a common centerline secured together by a
plurality of longitudinal fasteners (22) includes a substantially cylindrical
valve
body(12), a seat retaining plate, and at least one clip (16). The valve body
has a
peripheral edge portion and an axial end surface. The seat retaining plate
(28) 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 (48) and a radially outward portion (50). The
radially
inward portion secures the seat retaining plate to the valve body. The
radially
outward portion has an edge defining a first recess (70) and a second recess
(72).
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.
