Abstract
A flow control apparatus comprising: a housing, a housing passage disposed within the housing, a subterranean formation flow communicator for effecting flow communication between the subterranean formation and the housing passage, a flow control member, displaceable, relative to the subterranean formation flow communicator, for effecting at least opening of the subterranean formation flow communicator There is further provided a first actuation system for actuating displacement of the flow control member relative to the subterranean flow communicator. There is also provided a second actuation system for actuating displacement of the flow control member relative to the subterranean flow communicator. Relative to the central longitudinal axis of the housing passage, the first actuation system is angularly spaced from the second actuation system.
