Abstract
A valve having a trim comprising a plurality of a vortex flowpaths, each flowpath comprising a central vortex chamber and having three tangential inlet passages is provided. As the fluid flows through the inlet passages and enters the vortex chamber the flows start to turn and impinge upon one another, i.e., the flow entering via inlet passage will impinge upon the flow entering via inlet, the flow entering inlet will impinge on the flow entering inlet and the flow entering inlet will impinge on the flow entering inlet. As the flow entering vortex chamber impinges on another fluid flow as opposed to a wall of the flowpath the vortex can be used to create a flowpath with reduced erosion. The flow from the inlets combine in a radial flow within the vortex chamber and exit via the outlet which is substantially axial to the vortex chamber.
