Abstract
Methods and apparatus to diagnose a valve using electric valve actuators are disclosed. An example apparatus includes an electric motor to actuate a valve, rotation sensors to monitor a rotation of a drive shaft associated with the electric motor to determine a distance travelled by the drive shaft, and a valve position sensor to monitor a position of a flow control member of the valve. The example electric valve actuator further includes a processor to generate an alert based on feedback from the rotation sensors and the valve position sensor, the alert associated with a failure of the valve.
