1. A control valve comprising:
a valve body;
a flow control device disposed within the valve body, the flow control device having:
a wall extending around a central axis, the wall having an outer surface and an inner surface, the inner surface being disposed radially inward relative to the outer surface; and
a plurality of flow control channels formed in the wall, each flow control channel having a first end portion and a second end portion and extending in a first direction substantially parallel to the central axis and a second direction substantially perpendicular to the central axis from the outer surface toward the inner surface along a length extending entirely between the first end portion and the second end portion and terminating between the outer surface and the inner surface at an inner channel surface; and
a valve plug moveable relative to the flow control device in a direction substantially parallel to the central axis between a closed position and an open position such that in the closed position the valve plug covers the plurality of flow control channels, and as the valve plug transitions from the closed position toward the open position, the plurality of flow control channels become exposed to receive fluid flow.
