Abstract: A high range flow valve for precise supply of both low and high flows. The valve comprises two or more plungers movable inside a housing wherein the movement of each plunger relative to an adjacent plunger or the housing gradually opens or closes a flow opening and thus determines a flow area. Each plunger controls a different flow rate range. Two such valves can be combined in one housing whereby temperature and supply rate can be controlled, for both low and high supply rates.
