Beschreibung
Zusammenfassung:	A control valve includes a body having an inlet and an outlet and a valve seat positioned in a passageway between the inlet and the outlet. A valve plug is positioned within the body and is movable between an opened position and a closed position to modulate a fluid flow at the outlet. A cage is disposed within the body adjacent the valve seat and proximate the valve plug and has a circumferential wall having an outer surface and an inner surface aligned along a longitudinal axis of the cage. The outer surface of the cage defines an outer flow length and the inner surface defines an inner flow length that is less than the outer flow length.
