Abstract: An actuator comprising a main body which delimits a kinematic chamber inside which a valve and/or a relative drive mechanism of the valve is at least partially housed, a closing lid that can be associated to close the kinematic chamber of the main body, wherein the throttle body contains a position sensor, of the magnetic or magneto-resistive type, facing a slider of the valve and/or a component of the drive mechanism so as to read the position of the slider and therefore of the relative valve and/or of the relative component of the drive mechanism. Advantageously, the closing lid is provided with a screening device of electromagnetic fields for the position sensor and the slider, positioned near the position sensor, on the side opposite the kinematic chamber with respect to the position sensor.
