A technique facilitates actuation of flow control valves or other types of downhole devices. According to an embodiment, the downhole devices are coupled with corresponding first hydraulic control lines for hydraulically actuating each downhole device to a first operational position. The downhole devices also are coupled to a common second hydraulic control line which may be used in cooperation with selective hydraulic circuits to actuate individual downhole devices to a second operational position. For example, an individual selective hydraulic circuit may be coupled between each first hydraulic control line and the common second hydraulic control line at each downhole device. The selective hydraulic circuit is configured to enable actuation of the corresponding downhole device to the second operational position.
