摘要： A ball valve assembly including a valve body having opposing ends and an inside wall extending between the opposing ends. The inside wall forms a central passage and includes capturing portions disposed along the inside wall adjacent each of the opposing ends. The assembly also includes a valve ball rotatably supported within the central passage of the valve body and a valve stem extending through the valve body into the central passage and interengaging a ball valve for transmitting rotational motion thereto. The ball valve has an inside wall that forms a fluid passage therethrough. A pair of retainers is positioned within the central passage on opposing sides of the valve ball. Each of the retainers forms a fluid-tight seal between the valve ball and the valve body. A pair of press rings, captured at least partially within the central passage, is each in abutting engagement a different one of the retainers.
