  • Patent number: 10196874
    Abstract: A bonnet assembly for assisting to move a valve stem to a retracted position includes a bonnet body. The bonnet body has a bonnet valve end selectively connected to a valve, a bonnet actuator end opposite the bonnet valve end selectively connected to a valve actuator. A valve stem extends through the central bore of the bonnet body. A booster piston seal circumscribes the valve stem and engages an inner diameter of the central bore. The booster piston seal selectively defines an extent of a pressure cavity containing pressure media. An effective stem pressure surface faces in a direction towards the valve and is in fluid communication with the valve when the bonnet body is connected to the valve. A booster pressure surface faces in a direction towards the valve when the bonnet body is connected to the valve and is selectively acted on by the pressure media.

  • Patent number: 10107413
    Abstract: A valve assembly includes a valve body with a flow passage intersected by a valve cavity. A valve member is axially movable in the valve cavity between a closed position and an open position, the valve member having an opening that registers with the flow passage when the valve member is in the open position. A valve stem is threadingly connected to the valve member, the valve stem rotatable to move the valve member between the closed position and the open position. A collar assembly is located within a slot of the valve member and circumscribes the valve stem, the collar assembly having an annular collar shoulder. The valve stem has an annular load shoulder sized to engage the collar shoulder, limiting axial movement of the valve member.

  • Publication number: 20170130577
    Abstract: A system for directly sensing a position of a movable part of a hydrocarbon drilling and production includes a housing having a body with an inner cavity and a body wall with a wall thickness defined between an inner surface of the inner cavity and an outer surface of the body. The inner cavity has a fluid flow path for hydrocarbon development fluids. A moveable member is located within the inner cavity. A sensor assembly is located within one of the body wall and the moveable member, the sensor assembly being positioned within a port. An indicator feature is on the other of the body wall and the moveable member, the indicator feature sensable by the sensor assembly when the moveable member is in a set position.
