1. A system for use in a well, comprising:
a well tubing including an internal cross-sectional area;
a flow control valve mounted along the well tubing, the flow control valve comprising a housing and an internal piston moveably disposed within the housing, wherein a flow area of the flow control valve is equivalent to the internal cross-sectional area of the well tubing; and
an electrically powered actuator mounted externally to the flow control valve and connected to the internal piston via a linkage, the electrically powered actuator responding to electrical inputs to shift the internal piston to flow positions.
