Abstract
A device for the multifunctional control of the supply of a combustible gas to a burner apparatus is disclosed and comprises, in a main gas supply duct, an electromagnetically controlled electrovalve with an on/off function, a flow regulator downstream of this electrovalve and comprising a valve seat, a respective shutter associated therewith and controlled by a reversible electric motor, such as a step-by-step motor, for the control of the displacement of the shutter with respect to the valve seat. In the device the intercepted condition of the valve seat is detected and a signal correlated with the detected intercepted condition of the valve seat is generated this signal being adapted to supply the corresponding consent for the control to open or close the electrovalve, in order to enable or prevent the passage of gas through this duct in the phases of ignition and extinction of the burner respectively.
