1. A fluid valve comprising:
a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway; a trim assembly disposed within the fluid passageway; and a fluid control member movably disposed within the fluid passageway, the fluid control member cooperating with the trim assembly to control fluid flow through the fluid passageway; wherein the trim assembly includes a cage having a valve seat at one end and a first plurality of diamond-shaped openings disposed in a wall of the cage, the diamond-shaped openings extending through the cage perpendicularly to a longitudinal axis of the cage, the plurality of diamond-shaped openings including a first row of diamond-shaped openings located adjacent to one another about a circumference of the cage, each diamond-shaped opening in the first row having a longitudinal axis that is parallel to the longitudinal axes of other diamond-shaped openings in the first row and parallel to the longitudinal axis of the cage, and a second row of diamond-shaped openings located adjacent to one another about a circumference of the cage, each diamond-shaped opening in the second row having a longitudinal axis that is parallel to the longitudinal axes of other diamond-shaped openings in the second row and parallel to the longitudinal axis of the cage, the longitudinal axes of the diamond-shaped openings in the first row being offset from the longitudinal axes of the diamond-shaped openings in the second row, thereby forming a web of material between the diamond-shaped openings, the web of material having a first leg, a second leg, a third leg, and a fourth leg that intersect at a center portion.
