Abstract

According to an embodiment of the disclosure, a system for regulating a pressure differential includes a plurality of valving elements and a valve activation system. Each of the plurality of valving elements are configured to selectively allow and restrict at least a portion of a flow of fluid between an inlet and an outlet of a conduit through a respective opening and closing of each respective valving element. The valve activation system is configured to supply a common driving pressure to the plurality of valving elements. The common driving pressure is configured to initiate at least one of the opening or closing of the plurality of valving elements or to initiate the other of the opening or closing of the plurality of valving elements.
