A component for a ball valve that is configured to reduce noise. The component or “shoe” can install into the valve body, for example, on a downstream side of a throttling ball. In one implementation, the embodiments comprise an annular ring with an inner surface and an outer surface. The inner surface is cupped to receive a portion of the throttling ball. The outer surface may have a stepped profile with portions of the annular ring that have concentrically-decreasing diameter. This stepped profile sits in a corresponding recess in the valve body. Welds can be used to secure the shoe in place in lieu of fasteners, like bolts or screws.

A ball for use within a ball valve includes an outer wall, an inner wall that defines a central bore, and a lattice structure positioned within an interior space defined between the outer wall and the inner wall. The ball may include one or more flow conditioners positioned within the central bore. The ball may be formed via an additive manufacturing process.

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.

A technique facilitates valve operations in many applications including well related applications. A valve utilizes a piston which moves along an arc. The valve has an outer housing and an inner housing spaced to create an arcuate pressure chamber which extends along the arc. A piston is mounted in the arcuate pressure chamber for movement along the arc. A hydraulic force or other force may be selectively applied directly against an end of the arcuate piston to shift the arcuate piston along the arc. In some applications, the piston comprises a cutting edge oriented to enable performance of a cutting operation.

There is described a powder isolating valve which is capable of sealing valves from powder leakage during transport of powder and/or granular material. The valve comprises a rotatable valve closure member (14) and a pneumatically activated sealing mechanism containing a pair of resiliently deformable structures (18,20) extending around a surface of the rotatable valve closure member when the latter is in its closed position, the pair of resiliently deformable structures being held in a pair of annular recesses (32,34) which also extend around an surface of the rotatable valve closure member in its closed position, wherein the pair of resiliently deformable structures are capable of being pneumatically activated to force a sealing ring (26) against the rotatable valve closure member.
