Abstract: An actuator for adjusting a pilot valve in a gas supply regulator, includes a drive electric motor to provide rotational movement to a first drive shaft, an emergency electric motor to provide rotational movement to a second drive shaft, a differential gear arrangement coupled to the first drive shaft and coupled to the second drive shaft to generate rotational movement of an actuator drive shaft from the rotational movement provided by one of the first drive shaft and the second drive shaft, and a rotary to linear device coupled to the actuator drive shaft to convert rotational movement of the actuator drive shaft into a linear movement for adjusting the pressure valve.
