Abstract
A technique facilitates actuation of a downhole device, e.g. a flow control valve. The downhole device is shifted between positions by an actuator piston, which is movable in a first direction via hydraulic actuating fluid supplied by a first control line and in a second direction via hydraulic actuating fluid supplied by a second control line. A hydraulic circuit is coupled between the first control line and the second control line to enable a complete stroke of the actuator piston in one direction, e.g. the second direction, while limiting movement of the actuator piston to incremental movements in the other direction, e.g. the first direction. The hydraulic circuit employs a hydraulic enabled regulator having a plurality of pistons arranged to control the supply of hydraulic actuating fluid to achieve the desired incremental movements of the actuator piston.
