Abstract
A ball valve cage insert that includes: (1) a first section including an inlet ring having a radial wall thickness varies along the longitudinal axis of the cage; (2) a second section including side ribs that define a plurality of side openings, where the width of each opening varies from a first width at a first radial distance from the longitudinal axis to a second width at a second radial distance and (3) a third section including closure ribs extending from a first point at a first radial distance from the longitudinal axis to a second point where, as measured at a given radial distance from the longitudinal axis, the width of each closure rib varies from a first circumferential width at a first point on the longitudinal axis to a second width at a second point on the longitudinal axis.
