First Claim
1. A valve trim for a pressure reduction valve containing a plurality of high hydraulic flow resistance flowpaths therethrough, each flowpath comprising at least two inlets and at least one impingement zone, said impingement zone having two zone inlets in communication with the flowpath inlets and arranged substantially 180 degrees to one another and two zone outlets substantially perpendicular to the zone inlets and the flowpath inlets such that flow entering the two zone inlets mutually impinges on itself creating an area of high energy loss, and thereafter separates and exits through the zone outlets, each flowpath extending along at least three axes and being configured such that the totality of flow into each of the flowpath inlets enters the impingement zone before separating and exiting therefrom.

Abstract
A valve trim for a pressure reduction valve containing a plurality of high hydraulic flow resistance flowpaths therethrough. Each flowpath comprises at least two inlets (208, 209) and at least one impingement zone (210) having two zone inlets (211, 212) and two zone outlets (213, 214). The zone inlets (211, 212) communicate with the inlets (208, 209) and are arranged substantially 180 degrees to one another. The two zone outlets (213, 214) are arranged substantially perpendicular to the zone inlets (211, 212) such that flow entering the two zone inlets (211, 212) mutually impinges on itself creating an area of high energy loss, and thereafter separates and exits through the zone outlets (213, 214).
