Electric driven, integrated metering and shutoff valve for fluid flow control

A fuel control valve includes a rotary throttling valve assembly providing one or more of the benefits of being lightweight, having a relatively low power consumption, having a fail-closed structure and/or zero leakage. The fuel control valve is a rotary, throttling valve that is actuated via a rotary torque motor. The valve can be spring loaded for providing positive shutoff. Position indication of the valve is obtained via a position sensor and cam mounted to the throttling valve shaft at a driven end. In a de-energized state, a torsion spring is provided that is loaded to rotate the valve to the closed position. The fuel control valve may be advantageously utilized in extreme operating environments, e.g., such as extreme temperature and vibration environments found in missile control fuel systems.
