ABSTRACT:
An actuator includes, a first tubular, a second tubular longitudinally movably disposed within the first tubular and movable in response to fluid flow therethrough, the second tubular having a full bore therethrough, and a movable member movably attached to the second tubular and movable with the second tubular relative to the first tubular. The movable member is movable between a first position and a second position, the movable member is unobstructive of the full bore when in the first position and at least partially occluding of the full bore when in the second position, the movable member is movable from the first position to the second position in response to movement of the second tubular.
