摘要： A valve trim for use in a fluid flow control device. The valve trim includes a cage body defined by an outer cage wall and an inner cage wall coupled to the outer cage wall, the outer cage wall spaced radially outward of the inner cage wall. The valve trim also includes a plurality of first flow characterizing passages formed in the outer cage wall, and a plurality of second flow characterizing passages formed in the inner cage wall. The cage body is at least partially made of an erosion-resistant material.

摘要： 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.
