Fuel valve assembly

abababababababababA valve assembly comprises a valve body, a first valve, a second valve, and a manual override device. The valve body defines a first inlet, a second inlet, and an outlet. Each valve includes a plunger that is electrically movable between a position whereat the corresponding inlet communicates with the outlet and a position whereat the inlet is sealed from the outlet. The override device is manually movable to override positions whereat the electrical control of one of the valves is overridden and the plunger's seat-sealing surface is caused to move so that the corresponding inlet communicates with the outlet.
