Abstract: An apparatus for directing a fluid from an inlet to one of a plurality of outlets that are associated with a wellhead assembly includes a block body having a block inlet and a plurality of block outlets. A selector plug is located within the block body, the selector plug having a plug inlet aligned with the block inlet along a central axis, a plug outlet at an angle relative to the central axis, and a plug bore extending from the plug inlet to the plug outlet. A stem member is moveable to selectively rotate the selector plug within the block body so that the plug outlet aligns with one of the plurality of block outlets, providing a fluid flow path from the block inlet to such one of the plurality of block outlets, and impeding fluid communication from the block inlet to the others of the plurality of block outlets.

Abstract: An apparatus for sealing at least one hub bore of a multi-bore fluid hub associated with a wellhead assembly includes a plug body having a plug bore opening on an outer mating surface. A plug bore extends from a first end of the plug body to the plug bore opening. The plug body is selectively insertable into a hub housing of the multi-bore fluid hub. An insert is in engagement with the outer mating surface and is moveable relative to the plug body between an unengaged position, and an engaged position where the insert seals across one of the hub bores. A stem member is coupled to the plug body and is moveable to selectively rotate the plug body within the multi-bore fluid hub so that the plug bore opening aligns with one of the hub bores and the insert aligns with another of the hub bores.

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.

Abstract: A gate valve includes a valve body with a How passage intersected by a gate cavity. The gate valve also includes a gate with an axis, a downstream gate face, and an upstream gate face on an opposite side. The gate is axially movable in the gate cavity between a gate closed position and a gate open position. A seat ring is located between each gate face and the valve body, at the intersection of the flow passage and the gate cavity. An annular seal is located between each of the seat rings and the valve body. At least one annular filter is located between at least one of the seat rings and the valve body, each of the at least one filters being located radially inward from one of the seals relative to an axis of the flow passage.

Abstract: A gate valve includes a valve body with a flow passage intersected by a gate cavity. The gate valve also includes a gate with a gate body. The gate body has a downstream gate body face, and an upstream gate body face on an opposite side of the gate body. A seat ring is located between each gate body face and the valve body, at the intersection of the flow passage and the gate cavity. Each seat ring has a seat ring face proximate to the gate. At least one removable insert is located between one of the seat ring faces and one of the gate body faces. The insert is removably coupled to one of the faces and formed of a material harder and more wear resistant as compared to the gate body and the seat ring.

Abstract: An apparatus for assisting an actuator to close a valve has a cylindrical booster housing with a central axis. The booster housing includes an upward facing piston cavity and a downward facing lower cavity with internal threads for selectively coupling with external threads of a piston head of a valve actuator. A bulkhead is formed between the piston cavity and the lower cavity. The bulkhead has an opening for selectively accepting an actuator stem of the valve actuator therethrough. A booster piston is located within the piston cavity. The booster piston has a piston mounting means located on its bottom side for selectively securing a top end of the actuator stem of the valve actuator to the booster piston. The booster piston is moveable upwards in an axial direction to move the valve from a lower open position to an upper closed position.
