摘要 |
<p>A device for controlling the delivery of a combustible gas to a burner apparatus is provided including a main gas-delivery duct in which there is at least one servo-assisted diaphragm valve including a valve seat associated with a corresponding closure member with diaphragm control for opening the seat against the action of a resilient biasing member. The diaphragm valve includes a respective control solenoid valve with an electromagnetic operator for controlling the corresponding valve, the solenoid valve being arranged to bring about the opening/closure of a duct of a respective servo-assisted control circuit so as to operate the closure member of the valve indirectly, by the diaphragm control. The duct of the control circuit putting a portion of the main duct that is disposed upstream of the valve seat with respect to the direction of the gas-flow into flow communication with a respective control chamber of the diaphragm valve.</p> |
