Abstract

A technique facilitates control over at least one flow control assembly position to control fluid with respect to a tubing string. The flow control assembly is disposed along the tubing string and comprises a flow control valve and a motor to control the operational position of the flow control valve. The flow control valve may comprise a plunger and a seal system to provide a seal between the plunger and a surrounding structure. Additionally, the flow control valve comprises a pressure balanced system. The pressure balanced system serves to balance pressure acting on the plunger such that the motor is able to move the plunger by simply overcoming friction of the seal system without overcoming a pressure differential otherwise acting on the plunger.
