A control valve, comprising: a body having an inlet and an outlet; a valve seat positioned in a passageway of the body between the inlet and the outlet; a valve plug positioned within the body and movable between an opened position and a closed position to modulate a fluid flow at the outlet; and a cage disposed within the body adjacent the valve seat and proximate the valve plug, the cage comprising: a first end; a second end opposite the first end; a circumferential wall having an outer surface and an inner surface aligned along a longitudinal axis of the cage; a plurality of outlets formed in the outer surface; and a plurality of inlets formed in the inner surface; characterized in that: a longitudinal distance between a first outlet, closest to the first end of the cage, and a second outlet, closest to the second end of the cage, defines an outer flow length; and a longitudinal distance between a first inlet, closest to the first end of the cage, and a second inlet, closest to the second end of the cage, defines an inner flow length that is less than the outer flow length, wherein the plurality of outlets are in fluid communication with the plurality of inlets through a plurality of flow passages formed through the circumferential wall, and wherein each flow passage comprises an inlet section that extends generally radially, an outlet section that extends generally radially, and an intermediate section extending between the inlet section and the outlet section and each flow passage having a generally spiral shape about the longitudinal axis. a body having an inlet and an outlet;
