Abstract
A valve actuator including an electric motor is disclosed that includes a solid-state motor controller capable of operating a motor at variable speeds and a gear set that provides inherent braking. The speed and torque of the valve actuator may be selected. The speed and torque experienced by a valve may be varied over the length of a valve stroke. The valve actuator may include logic sufficient to act as a process controller.
