A control valve having a shiftable valve plug includes a valve body having an inlet, an outlet, a flow passage extending between the inlet and the outlet, and defining a longitudinal axis, a generally cylindrical valve cage disposed within the valve body and sized to receive the valve plug, with the valve cage including at least one aperture comprising at least a portion of the flow passage, a portion of the valve cage disposed adjacent a portion of the valve body at an interface. A seal having a C-shaped cross section is provided and is disposed at the interface between the valve cage and the valve body, and a retainer is disposed adjacent the interface and positioned to secure the seal against movement along the longitudinal axis.

A fluid flow control device includes a body defining an inlet, an outlet, and a fluid flow path extending from the inlet to the outlet. A valve seat ring is coupled to the body and defines an orifice through which the fluid flow path passes. A cage is also coupled to the body and defines an interior bore, wherein the cage includes at least one passage through which the fluid flow path passes. A throttling element is sized for insertion into the cage interior bore and movable along an axis between open and closed positions. The throttling element defines a sealing surface oriented substantially parallel to the axis. A seal is positioned to engage the sealing surface when the throttling element is substantially in the closed position, thereby to restrict fluid flow through the valve seat ring orifice.

Fluid pressure reduction devices for use in gas and liquid handling systems are disclosed. An example fluid pressure reduction device includes a plurality of cylinders, each having an inner diameter surface and an outer diameter surface and a plurality of apertures that extend from the inner diameter surface to the outer diameter surface. The cylinders are arranged in a nested configuration so that a substantial portion of the inner diameter surface of one of the plurality of cylinders is in contact with a substantial portion of the outer diameter surface of another one of the cylinders. Portions of the apertures of one of the cylinders overlap at least portions of the apertures of another one of the cylinders to form a process fluid flow path.

Methods, apparatus, systems and articles of manufacture for valve trim apparatus for use with control valves are disclosed. An example valve trim apparatus for use with a fluid valve includes a cage positioned in a fluid flow passageway of a valve body, the cage including a primary valve seat and a secondary valve seat; and a valve plug slidably positioned within the cage, the valve plug including a primary sealing surface to sealingly engage the primary valve seat and a secondary sealing surface to sealingly engage the secondary valve seat, the primary sealing surface adjacent to a first end of the valve plug and the secondary sealing surface spaced away from the primary sealing surface along a longitudinal axis of the valve plug toward a second end of the valve plug, the valve plug having a first portion extending from the primary sealing surface toward the secondary sealing surface to form a flow restricted passage between an inner surface of the cage and the first portion, the valve plug having a second portion extending from the first portion to the secondary sealing surface to form a recovery plenum between the second portion and the inner surface of the cage, wherein a first diameter of the first portion is less than a second diameter of the second portion.

A control valve has a cage disposed within a valve body adjacent a valve seat and proximate a valve plug to provide guidance for the valve plug. The cage includes a solid, unitary circumferential wall with inlet passages adjacent one of an inner surface or an outer surface and outlet passages adjacent the other of the inner and outer surface. An annular cavity is spaced apart from the inner and outer surfaces and is connected to the inlet passages. Intermediate passages are connected to the annular cavity and recovery plenums interconnect the intermediate passages and the outlet passages. The recovery plenums have cross-sectional areas that are larger than a cross-sectional areas of the intermediate and outlet passages.
