Abstract: A short stroke flow control device or valve which is adapted to provide velocity control trim in a short stroke. The valve constructed in accordance with the present invention comprises multiple disk stacks or cages which are separated from each other by intervening spacers, and are placed axially in a valve gallery clamped between a seat ring and bonnet of the valve. The fluid passageways in the cages are throttled in a controlled manner by a plug which defines multiple throttling elements or plug lobes, the number of plug lobes defined by the plug preferably being equal to the number of cages included in the valve. The plug lobes of the plug control the flow of fluid through the disk stacks or cages in tandem. All of the throttling elements or plug lobes of the plug, with the possible exception of the plug lobe which contacts the seat ring for closure, is larger in diameter than the remainder of the plug and has at least one kidney bean shaped flow passage extending therethrough.

Abstract: A valve having a trim comprising a plurality of impingement flowpaths, each flowpath comprising a central impingement chamber and having three radially directed inlet passages is provided. As the fluid floes through the inlet passages and enters the impingement chamber the flow starts to turn and impinge upon one another at a substantially central point within the impingement chamber and exit together via the outlet which is substantially axial to the impingement chamber. As the flows entering the impingement chamber impinge on one another as opposed to a wall of the flowpath, the impingement can be used to create a flowpath with reduced erosion.

Abstract: In accordance with the present invention, there is provided a dirty service valve including an axial trim which, as a result of its structural attributes and extended stroke length, provides increased Cv capacity relative to valve plug size in comparison to existing prior art designs. In accordance with one embodiment of the present invention, the axial trim integrated into the valve of the present invention is configured to provide a linear flow characteristic. In accordance with an alternative embodiment of the present invention, the axial trim may be configured to provide a non-linear flow characteristic which, coupled with the extended stroke length thereof, provides improved flow control in addition to increased Cv capacity. The axial trim possessing the above-described structural and functional attributes may also be integrated into an axial body or housing, thus making the use of rotary actuators in conjunction with the axial trim more feasible.
