Patent number: 8720854Abstract: A seal assembly is provided for a rotary ball valve having a top-mounted bonnet, thereby allowing the seal assembly to be installed and removed without removing the valve from the pipeline. In an embodiment, the seal assembly may include a seal ring disposed within the valve interior and biased toward the ball element of the valve. A seal carrier may be disposed between the seal ring and the valve body, and the seal carrier may be removably secured to the valve body by a plurality of bolts disposed in the valve interior. A primary leak path may exists between the seal ring and the seal carrier and a secondary leak path may exists between the seal carrier and the valve body. A first and second auxiliary seal may prevent fluid flow through the primary and secondary leak path, respectively.Type: GrantFiled: April 30, 2010Date of Patent: May 13, 2014Assignee: Fisher Controls International LLCInventors: Paul R.

Patent number: 8096524Abstract: 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.Type: GrantFiled: April 27, 2010Date of Patent: January 17, 2012Assignee: Fisher Controls International LLCInventors: Paul R.
