Abstract
An individual spray nozzle contains two or more valves that are actuated by time or frequency modulated signals such as pulse width modulated (PWM) signals. The PWM signals are interleaved to open and close each of the respective valves that enable fluid to flow from an input to a combined output. The opening and closing positions of two or more different valves are interleaved to increase the range of performance, such as to increase the frequency of fluid flow from the input to the combined output. Additional embodiments are described.
