Abstract
An example valve includes a valve body, a cage, and a plug. The valve body includes a fluid passageway extending between a fluid inlet and a fluid outlet. The cage and the plug are disposed in the fluid passageway. The cage includes a first annular sidewall having an inner layer and an outer layer that circumscribes the inner layer. The inner layer includes first openings extending through the inner layer. The outer layer includes second openings extending through the outer layer. The second openings are in fluid communication with the first openings. The second openings are smaller than the first openings. The plug includes a second annular sidewall circumscribed by the first annular sidewall. The second annular sidewall includes third openings extending through the second annular sidewall. The plug is movable relative to the cage to selectively place the third openings in fluid communication with the first openings.
