  • Flow control valve and method for using the same
    Patent number: 6945264
    Abstract: A flow control module has a valve body with a bore extending therethrough and a first disc occupying substantially the entire area of the bore and having at least one aperture extending therethrough. The valve body also includes a second disc adjacent to the first disc wherein the second disc also occupies substantially the entire area of the bore and has at least one aperture extending therethrough. The discs are rotated so that the apertures may align to increase or to reduce flow therethrough. The valve body also includes a check valve proximate to the first disc and the second disc to close and prevent backflow. Arranging multiple flow control modules in line in a system provides incremental pressure drops to achieve a total pressure drop in stages while minimizing or eliminating cavitation.
