description A device for controlling the delivery of a combustible gas to a burner apparatus is provided. The device includes a main pipe for delivery of the gas in which are disposed first and second servovalves in cascade with each other, with respect to the direction of flow of the gas. The servovalves include respective valve seats associated with corresponding shut-off means with diaphragm control for the opening of the seats. The first and second servovalves include respective first and second control solenoid valves with electromagnetic operating means to control the opening/closing of the corresponding servovalve. The solenoid valves are arranged to act to open/close the pipes of respective servo-assisted control circuits, so as to control indirectly, by way of the diaphragm control, the respective shut-off means of the corresponding servovalve the pipes of the control circuit placing the main pipe in fluid communication with respective control chambers of the servovalves.
