Abstract
A technique facilitates controlling flow in a wellbore. One or more flow control valve assemblies may be designed for coupling with downhole well equipment. Each flow control valve assembly comprises a flow control valve which cooperates with a control module. The control module comprises a plurality of electrically controlled valves arranged to control flow of actuating fluid to the flow control valve. Each flow control valve assembly also comprises a hydraulic override system to enable hydraulic actuation of the flow control valve to a predetermined position when, for example, no electrical power is available for the electrically controlled valves of the control module.
