Abstract

A tool, e.g. a downhole tool, utilizes at least one actuator which may be actuated rapidly between positions during operation of the tool. The actuator is moved via flow of an actuating fluid controlled by a main valve which, in turn, is controlled via a pilot valve. The pilot valve is operated to selectively control flow of the actuating fluid to the main valve so as to shift the main valve between desired operational positions.
