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).
