Zusammenfassung:	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.
