Abstract
An electronic control system for safely operating a pair of redundant solenoid type valves is disclosed. The system utilizes an alternating current potential for energizing the valves. The first valve is energized across the applied potential and then is placed in series with the second valve. The series combination is selected so that once the valves are energized they will stay energized in the series configuration.
