A flow conditioner of a valve assembly includes a body including a longitudinal axis, a first end, a second end, and a flow path connecting the first end and the second end. A non-planar surface is formed in the first end of the body. A plurality of channels define the flow path and extend parallel to the longitudinal axis. At least one channel of the plurality of channels has a length different from a length of an adjacent channel of the plurality of channels. A cylindrical housing surrounds the plurality of channels and includes a first end and a second end. The first end is proximally located to the first end of the body. The non-planar surface of the first end is defined in part by an end of the at least one channel of the plurality of channels.

An attenuator dome for a ball valve includes a body defining an upstream surface and a downstream surface. The body has first and second attenuation sections. The first attenuation section has a single stage with a first plurality of passages extending from the upstream surface to the downstream surface. The second attenuation section has a first stage with a second plurality of passages extending from the upstream surface to a first plenum formed inside the body and a second stage with a third plurality of passages extending from the first plenum to the downstream surface. The single stage of the first attenuation section has first flow area percentage, the first stage of the second attenuation section has a second flow area percentage less than the first flow area percentage, and the second stage has a third flow area percentage greater than the second flow area percentage.

A flow control valve includes an inlet, an outlet, and defines a fluid flow path. A valve seat is disposed within a valve body, and a valve plug in the valve body is surrounded by a cage. An exterior surface of the valve plug includes a plurality of notch sets, each notch set spaced apart from an adjacent notch set along the longitudinal axis, and the cage is disposed within the valve body and arranged to retain the valve seat, with an interior of the cage including a plurality of annular recesses. The annular recesses are spaced apart along the longitudinal axis, and the cage includes a plurality of apertures forming a portion of the fluid flow path. The notch sets and the recesses are arranged to form a plurality of turns in the fluid flow path when the valve plug is shifted toward the open position.

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 control valve for controlling a gaseous volumetric flow rate, in particular a steam volumetric flow rate, having a valve housing, a valve seat, and a valve throttle element which can be moved relative to the valve seat along a movement axis. The valve housing shapes the valve seat, and the movable valve throttle element has a throttle edge region which interacts with the valve seat. The control valve has multiple volumetric flow rate swirl elements which interact with the throttle edge region and which prevent or at least reduce shear layer instabilities in a shear layer between a wall jet region of the gaseous volumetric flow rate and a core flow region of the gaseous volumetric flow rate.

A fluid flow control device include a valve body including an inlet, an outlet, and a passageway extending between the inlet and the outlet. A valve trim is at least partially disposed in the passageway of the valve body. The valve trim includes a restrictor having a wall and a plurality of passages extending through the wall. A diffuser is coupled to the restrictor and including a porous body. The porous body is adjacent to the plurality of passages of the restrictor.

An example valve includes: a pressure compensation spool configured to be subjected to a first fluid force of fluid received at a first port acting in a proximal direction; a pressure compensation spring disposed in a pressure compensation chamber and applying a biasing force on the pressure compensation spool in a distal direction; a turbine configured to rotate as fluid flows through the valve; and a flow area configured to throttle fluid flow from the first port to the pressure compensation chamber, wherein fluid in the pressure compensation chamber applies a second fluid force on the pressure compensation spool in the distal direction, such that the pressure compensation spool moves to a particular axial position based on force equilibrium between the first fluid force, the second fluid force, and the biasing force to throttle fluid flow from the pressure compensation chamber to a second port.
