Abstract
A mechanical flow control device is provided that allows flow of production fluids along an annular path and across an valve body. A sliding sealing member can be mechanically transitioned between an opened flow position and a closed flow position as desired. The mechanical flow control device may be combined with one or more interventionless flow control devices.
