The subsea manifold assembly may comprise a header bore fluidly connected to one or more branch connections. A unidirectional valve is included at the branch connections to allow fluid leakage from the closed cavity into a header bore of the subsea manifold assembly to thereby reduce a pressure within the cavity while in the closed position.

Abstract: An integrated air valve includes a hollow shell formed with a valve installation space, two air holes respectively an air inlet hole and an exhaust hole communicated to the space, and two support members; two lever members; and two shape memory alloy members.

A part of the shape memory alloy members are hung on the actuating ends of the lever members, and capable of driving the lever members based on an energized state. One of the lever members determines conduction of the air inlet hole to achieve air intake, the other lever member determines whether the exhaust hole communicates to an external space to achieve exhaust, and the lever members determine whether the integrated air valve enters air pressure maintenance.

Embodiments also include systems to prevent dislodging of a choke seat when backpressure is supplied to the choke system. Embodiments also include sealing systems to prevent fluid leaks around the choke seat of the choke system.

Abstract: A two-piece valve shell (body and bolted-on top bonnet having external fins to dissipate heat) structure reduces possible leakage paths while also providing a top-side ball/stem installation/removal path (when the bonnet piece is not present) to facilitate initial valve assembly as well as subsequent inspection/removal of the ball/stem and other valve internals for conducting valve maintenance without requiring the valve body to be removed from its process connections. In some implementations, a second/bottom bonnet is also attached to the body such that it covers another opening to the ball cavity.

Abstract: A valve, such as a ball valve, can include a noise attenuation assembly to control fluid expansion through the valve and provide noise abatement. The valve can include a valve body and a valve stem and the noise attenuation assembly can include a flow control body and a trim body. The flow control body can be coupled to the valve stem and the flow control body can be configured to selectively permit fluid flow through the valve body in an axial direction. The trim body can include a plurality of channels to control fluid expansion during fluid flow through the valve body. The trim body can be engaged with the flow control body at first and second mounting structures of the flow control body to secure the trim within a fluid pathway of the flow control body.

Abstract: In one example, a fluid flow restrictor has a housing outlet offset from a housing inlet along a fluid flow direction so as to define a channel therebetween. A rotatable body that is disposed in the channel defines a bore that extends entirely therethrough such that the bore defines a bore inlet and a bore outlet. The flow restrictor has an interior surface disposed in the bore that defines an orifice having a cross-sectional dimension that is less than a cross-sectional dimension of the channel such that the orifice can restrict a flow of fluid as the fluid flows between the housing inlet and outlet. The rotatable body is rotatable between 1) a first orientation, where the bore outlet is offset from the bore inlet along the fluid flow direction, and 2) a second orientation, where the bore inlet is offset from the bore outlet along the fluid flow direction.

Abstract: A rotary disc valve includes a guide assembly having a ring-shaped member having a groove disposed in an inner surface thereof, and a valve disc assembly rotatably coupled to the guide assembly. The valve disc assembly includes a valve disc, a projection received within the groove of the guide assembly, and a chimney support coupled to the guide assembly. The chimney support includes a seal member for selectively sealing against the valve disc. The groove has a main portion perpendicular to a longitudinal axis of the rotary disc valve, and an angled portion at an oblique angle with respect to the longitudinal axis. When the valve is moved between a closed and open positions the valve disc assembly is rotated and moves the projection along the angled portion of the groove, thereby moving the valve disc toward and away from the seal.
