ABSTRACT:
A valve assembly having a housing which includes a central, substantially cylindrical body part and a pair of end connector parts is provided in which the body part defines a through-flow fluid passageway, the end connector parts define upstream and downstream fluid flow passages, and each connector part is adapted to position an annular, ball-seating-sealing gasket. A ball is operatively carried within the passageway of the body part for opening and closing movement in operating engagement with the seating-sealing gaskets.
A bottom entry stem is utilized in positive latching engagement with the ball, as effected by at least three cooperating pairs of complementary, side-engaging, depthwise extending wall surfaces which substantially preclude endwise float of the ball between the seating gaskets, permit pivotal insertion and removal of the ball from the body, and permit radial, in-latching float of the ball with respect to the longitudinal axis of the stem.
