  • Patent number: 10982787
    Abstract: In an actuated valve assembly, the valve includes a valve body defining a fluid passageway, an annular valve seat disposed on the valve body surrounding the fluid passageway, and a valve closing member movable between a closed position sealing against the valve seat and a fully open position spaced apart from the valve seat to permit flow. The actuator includes an actuator housing and an actuating mechanism movable within the actuator housing, by operation of the actuator, between a closing position in which the actuating mechanism holds the valve closing member in the closed position, and an opening position in which the actuating mechanism permits movement of the valve closing member toward the fully open position, the opening position being defined by engagement of the actuating mechanism with a stop portion of the actuator.

  • Publication number: 20210108738
    Abstract: An actuator includes a housing defining an inlet port, a piston and a return spring disposed within the housing, and an elastically deformable element. The return spring is configured to apply a biasing force to the piston to move the piston to a spring return position. A first fluid pressure applied to the inlet port moves the piston against the biasing force of the return spring to a first actuated position in which the piston indirectly engages a stop portion of the actuator housing. A second fluid pressure, greater than the first fluid pressure, applied to the inlet port moves the piston against the elastically deformable element to compress the elastically deformable element to move the piston to a second actuated position beyond the first actuated position.

  • Publication number: 20200224773
    Abstract: A valve includes a valve body with an annular valve seat having a first central axis, and a valve closure subassembly assembled with the valve body and including an axially movable valve stem and a stem tip attached to the valve stem by a stem connector and including an annular seal portion having a second central axis. When the first central axis is misaligned with the second central axis, the stem tip is pivotable about the valve stem to effect angular adjustment of the annular seal portion of the stem tip into uniform sealing engagement with the annular valve seat when a closing force is applied to the valve stem. The stem connector is configured to resist pivoting movement of the stem tip when the valve stem is in the open position.

  • Patent number: 10690259
    Abstract: A manually actuated valve assembly includes a valve body defining a flow passage, a valve member assembled with the valve body, an actuator housing assembled with the valve body, an actuator stem having an upper stem portion coupled with a lower stem portion by a coupling, a rotatable actuator drive member coupled to said upper stem portion, and a biasing spring disposed in the actuator housing. The actuator drive member is rotatable between a first stop position corresponding to a fully open valve position, and a second stop position corresponding to a fully closed valve position. The coupling between the upper stem portion and the lower stem portion is configured to provide an over-travel condition between the actuator drive member and said actuator stem configured to provide a closed valve condition at a predetermined rotational position of the actuator drive member that is offset from the second stop position.

  • Patent number: 8490945
    Abstract: A valve includes a valve body, a valve element to selectively control flow through the valve, and a seal member and seat member together providing a fluid-tight seal between a valve cavity and a fluid passage in the valve body. A live-loaded biasing member is adapted to apply a live-loaded sealing force to the seat member to bias the seat member toward sealing engagement with the valve element. When the pressure in the fluid passage exceeds the pressure in the valve cavity, an unbalanced passage pressure load biases the seat member toward sealing engagement with the valve element. When the pressure in the valve cavity exceeds the pressure in the fluid passage, an unbalanced cavity pressure load biases the seat member toward sealing engagement with the valve element. The live-loaded sealing force is in parallel with each of the unbalanced passage pressure load and the unbalanced cavity pressure load.
