    摘要： A valve body construction comprising a tubular body member with a closure received in one end thereof against an internal shoulder or other inward abutment. A segmented thrust ring is received in a groove around the inner wall of the body member outward of the closure to hold it in place. A lock ring has a conical axial extension that engages complementary conical inner surfaces on the thrust ring segment to force the segments radially outward, whereby complementary wedging surfaces on the thrust ring and the wall of the retainer groove force the segments axially against the closure to clamp it in place.

    摘要： A gate valve operated by a pressure-fluid-actuated ram with a piston mounted on the end of the stem. The stem is slidably received in stem seal assemblies on the valve bonnet and the fluid cylinder, with the valve stem seal assembly being in a floating mount to facilitate alignment with the valve stem seal while maintaining the integrity of the fluid seal.

    摘要： A two-stage opening globe valve including the main valve member with a chamber therein receiving the valve stem to permit limited relative axial movement between them. Coaxial and lateral primer ducts connect the chamber to the upstream and downstream flow passages, and on the end of the stem is a primer valve that opens and closes the coaxial duct. When the stem is moved to open the valve it opens the primer valve first while an imbalance in opposing areas of the main valve closure which are exposed to upstream pressure produces a force differential biasing the valve toward closed position.
