A composite fracturing tree includes an operating valve and a master valve in fluid communication with the operating valve. The master valve includes an inlet portion in fluid communication with the operating valve, an outlet portion, and a gate portion. The gate portion is disposed between the inlet portion and the outlet portion. The gate portion is moveable between a flow position and an occluding position. In the flow position, the gate portion permits flow between the inlet portion and the outlet portion. In the occluding position, the gate portion prevents flow from the inlet portion to the outlet portion. The gate portion is actuated from the flow position to the occluding position with a closing force and from the occluding position to the flow position with an opening force. The master valve allows for the closing force to reduced compared to conventional fracturing valves.

An apparatus for actuating an end-member is disclosed. The apparatus includes a housing, a spring within the housing, and a spring plate forming a restriction for the spring within the housing. A brake member is associated with the spring plate for retaining the spring plate in one or more positions. A drive rod is associated with a motor to enable a first movement of the drive rod and to enable a second movement of spring plate. The first movement or the second movement enables the actuating of the end-member in one or more different positions for the end-member. The brake member may be engaged or disengaged to control or decouple spring compression forces in the actuator when the spring is compressed.

Actuator with spring compression and decoupling

A system for converting operation of a valve between an unbalanced operation mode and a balanced operation mode includes a housing adapted to couple to a valve body. The system also includes a lower stem, including lugs, the lugs having a lug diameter that is larger than an adjacent lower stem diameter. The system further includes a valve member nut coupled to a valve member, the valve member nut having an opening to receive the lower stem, and pins extending into the opening, the pins forming a reduced diameter portion of the opening. In the system, the lower stem couples to the valve member, via the valve member nut, when the lugs are axially aligned with the reduced diameter portion and the lower stem decouples from the valve member when the lugs are axially misaligned with the reduced diameter portion.

System and method for convertible balanced and unbalanced stem valve

Embodiments of the present disclosure include a system for coupling objects in a wellbore includes a unidirectional valve having a body. The body includes two or more body lugs extending radially outward, each body lug of the two or more body lugs extending at least a portion of a circumferential distance of the body. The system also includes a tubing hanger having a bore that receives the unidirectional valve. The bore includes an axial restraint system that receives the two or more body lugs and blocks axial movement of the unidirectional valve in a first position and enables axial movement of the unidirectional valve in a section position, the unidirectional valve being non-threadingly coupled to the tubing hanger.

Axially restricted pressure shuttle

A system includes an actuator housing having a plurality of adapter lugs extending radially inward toward an axis, each adapter lug of the plurality of adapter lugs secured to the housing via a respective connector. The system also includes a bonnet having a plurality of bonnet lugs extending radially outward away from the axis, each bonnet lug of the plurality of bonnet lugs being separated by a respective space, the space being sized to permit axial movement of an adapter lug of the plurality of adapter lugs toward a lower flange arranged axially lower than the plurality of bonnet lugs.

No-bolt latching system

Embodiments of the present disclosure include a system for controlling a fluid flow. The system includes a valve body including a bore extending along an axis, an inlet, and an outlet, wherein a flow passage extends transverse the axis from the inlet to the outlet, a stem extending through the bore along the axis, and a valve member coupled to the stem. The valve member is movable along the axis, via the stem, between a closed position where the valve member blocks the flow passage to an open position where the valve member does not block the flow passage. The system also includes a balancing system coupled to the valve member, the balancing system comprising a tether and a balance member, wherein an opening force unseating the valve member is translated to the balance member.

Balanced stem and surface safety valve

A valve assembly includes a valve body and a valve member configured to translate between an open and a closed position. The valve assembly also includes a bonnet coupled to the valve body and a valve stem coupled to the valve member. The valve assembly also includes an actuator coupled to the bonnet. The actuator includes a first drive mechanism positioned to translate a first driving force to the valve stem, the first drive mechanism being in operation during a normal operating condition. The actuator also includes a second drive mechanism positioned to translate a second driving force to the valve stem, the second drive mechanism being in operation during a fail-safe operating condition.

Multi-motion fail-safe operating gate valve

A system for securing a valve actuator to a valve assembly includes an actuator housing with a plurality of housing lugs protruding radially. A cylinder assembly is located within the actuator housing and has a horseshoe connector to engage a valve stem nub of a valve stem and transfer axial movement of the horseshoe connector to axial movement of the valve stem. A bonnet has a plurality of bonnet lugs protruding radially from the bonnet to define a plurality of bonnet slots therebetween, wherein each of the plurality of housing lugs are sized to pass axially through a respective one of the plurality of bonnet slots when the actuator housing is in a released position, the actuator housing being rotatable to a locked position such that the plurality of bonnet lugs prevent axial movement of the actuator housing in at least one direction.

An overpressure safety system for use with a distribution of pressurized fluid associated with hydrocarbon production operations includes a safety valve in fluid communication with a main bore of a fluid control manifold assembly. The safety valve has a blocking condition where the safety valve blocks a flow of pressurized fluid through the safety valve, and a venting condition where the safety valve provides a fluid flow path for the pressurized fluid at a set overpressure to pass through the safety valve. A valve member is moveable within the safety valve between a first position where a pressure side of the valve member blocks the flow of the pressurized fluid at a pressure below the set overpressure from passing through the safety valve, and a second position where the valve member provides a fluid flow path for the pressurized fluid at any pressure to pass through the safety valve.
