Abstract
Cage apparatus having fluid passageways to affect flow characteristics of valves are disclosed. An example valve cage includes clustered fluid flow passages. Each fluid flow passage has a first portion connected to a second portion. The first portion tapers towards the second portion and the second portion tapers towards the first portion. The clustered fluid flow passages include a first row and an adjacent second row. The first row and the second row are oriented at a first angle relative an axis of the valve cage to extend along a helically-shaped path on the valve cage.
