A trim assembly is located within the fluid passageway, the trim assembly controlling fluid flow through the fluid passageway. The trim assembly includes valve plug having an integrated staged pressure recovery.

Plug integrated staged valve trim assembly and fluid control valve comprising same

A non-plugging, multi-stage valve trim and a fluid flow control device employing the same. The valve trim includes a unitary cage body extending along a longitudinal axis, and a valve plug movably disposed within the unitary cage body to control fluid flow through the unitary cage body. The unitary cage body includes an outer wall arranged to engage the valve body, an inner wall spaced radially inwardly of the outer wall, a cage inlet formed in the outer wall, a cage outlet formed in the outer wall, and a pressure reducing fluid flow passageway formed within the unitary cage body and extending between the cage inlet and the cage outlet.
