An apparatus for remotely controlling fluids in a well is provided. The flow control apparatus may include a body member having a flow port in an outer wall of the body member, and a flow aperture spaced inwardly from the outer wall. A remotely shiftable valve member may be disposed for reciprocal movement within the body member to regulate fluid flow through the flow aperture and flow port. An indexing sleeve may be rotatably disposed within the body member and engaged with the shiftable valve member to shift the valve member within the body member. An operating piston may be engaged with the indexing sleeve and movably disposed within the body member in response to pressurized fluid. A locking mechanism may also be included for locking the shiftable valve member in a closed, or sealing, position. Electrically-operated mechanisms for shifting the valve member is also provided.
