ABSTRACT:
A piloting actuator valve controls flow in a well. The piloting actuator valve is combined with a downhole completion and utilizes a pilot valve to control actuation of a main valve. A controllable actuator is coupled to the pilot valve and enables selective control over the pilot valve which, in turn, controls the state of the main valve.
