  • Publication number: 20240003434
    Abstract: A system including a valve. The valve includes a valve body having an interior volume and a bore along a first axis. A stem extends along a second axis and a flow control element couples to the stem. The stem selectively moves the flow control element through the interior volume between a closed position and an open position relative to the bore. A valve insert system retains a pressurized lubricant in the interior volume.

  • Patent number: 10443740
    Abstract: Provided in some embodiments is a system that includes a split gate valve including first and second gate sections coupled together and configured to move together within a cavity of the split gate valve between an open position and a closed position. The split gate valve includes a rolling actuator to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections between the open and closed positions. In other embodiments is provided a method that includes converting a rotational input into a linear motion to activate a split gate valve via a rolling actuator. The method also includes seating first and second gate sections of the split gate valve against opposite first and second seats to provide a double seal.

  • Patent number: 10119615
    Abstract: A method of manufacturing a sealing component includes defining a configuration for the sealing component, wherein the configuration comprises a cross-section comprising a first wall and a second wall joined by a turning wall to form a generally U-shape, the first wall and the second wall comprising a variable cross-sectional thickness, wherein the cross-section is taken along a plane extending along an axial axis of the sealing component and the cross-section extends in a circumferential direction. The method also includes depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a layer according to the defined configuration.
