description An apparatus and method for controlling a pressure drop of a fluid is disclosed. A sleeve includes a plurality of flow passages in a wall of the sleeve. A member slides relative to the sleeve to reveal at least a portion of the plurality of flow passages to control flow of the fluid through the flow passages. The plurality of flow passages are at azimuthally-and axially-staggered locations around the sleeve.
