A valve assembly for managing a flow of fluids in hydrocarbon development and production operations includes a valve body having an internal body cavity and a body bore intersecting the body cavity. A valve plug is located within the body cavity and is rotatable between an open position and a closed position. A sleeve is located between the valve plug and the valve body and is rotationally fixed to the valve body and remains rotationally static relative to the valve body as the valve plug rotates. A seal groove is located on a sidewall surface of the sleeve and circumscribes one of the sleeve openings. A seal assembly has a seal ring that is U shaped in cross section with an inner leg that engages the seal groove and an outer leg that extends out of the seal groove and engages one of the valve body and the valve plug.
