Abstract
An apparatus and method for controlling a solenoid valve wherein the flow rate of the valve relative to a specific percent duty cycle may be varied. The controller is such that after the desired flow of the solenoid valve is determined, the frequency and percent duty cycle of an output signal controlling the solenoid valve is varied. Such a controller utilizes varying frequencies to provide multiple slope flow rates with a single passage solenoid valve.
