Title of the Invention: MODULATING FAILSAFE VALVE ACTUATOR USING DIFFERENTIAL GEARING ABSTRACT OF THE INVENTION A power operated rotary valve actuator utilizing a differential drive and magnetic clutch to provide continuous valve positioning between full open and full closed positions. The valve drive motor operates through a differential drive and in conjunction with a single electric clutch provides sequential application of rotational torque to a stored energy spring and the valve shaft. The sequential torque application minimizes drive system torque requirements and insures that sufficient energy is available to return the valve to a pre- selected position at any time during normal operation.
