Disclosed herein is a flow-actuated actuator. The actuator includes, a tubular with a flow passageway having a first flow area, and at least one movable member in operable communication with the tubular. The at least one movable member is movable relative to the tubular between at least a first position and a second position, the at least one movable member configured to form a second flow area that is smaller than the first flow area when in the second position, the flow-actuated actuator is configured to move a separate member in response to fluid flow therethrough.
