摘要

A fluid valve includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve seat is disposed within the fluid passageway. A fluid control member is movably disposed within the fluid passageway, the fluid control member cooperating with a trim assembly to control fluid flow through the fluid passageway. The trim assembly includes a cage having a plurality of openings that characterize fluid flowing through the cage and a plurality of vents that suppress noise generated by the plurality of openings.
