Abstract
Provided is a valve assembly system including a flowbody including a channel formed at an inner surface thereof, a butterfly plate disposed within the channel and rotatably mounted within the flowbody. The system also includes a pair of dual-sided pistons that receive differential pressure at an input side and an output side of the valve assembly system. A spring is controlled for biasing against at least one of the dual-sided pistons based on the differential pressure, and to rotate the butterfly plate to regulate the differential pressure and the valve assembly system to a predetermined output pressure.
