Wellbore flow control device

A selectively operable flow control device for regulating fluid flow in a well, comprising:

• a body member having a central bore extending therethrough, at least one flow port, and a first valve seat;
• a sleeve member movably disposed within the central bore of the body member, and having a second valve seat adapted for cooperable sealing engagement with the first valve seat;
• a piston connected to the sleeve member and movably disposed within the central bore of the body member in response to application of pressurized fluid;
• a first and a second hydraulic conduit connected between a source of pressurized fluid and the body member, the first hydraulic conduit being in fluid communication with a first side of the piston, and the second hydraulic conduit being in fluid communication with a second side of the piston;
• and
• a position holder cooperably engageable with a retaining member, one of the position holder and the retaining member being connected to the sleeve member, and the other of the position holder and the retaining member being connected to the body member.
