Gas control device, having a safety valve, a main gas valve and a pressure regulator, the safety valve being configured as a diaphragm valve with a gas inlet chamber and a drive chamber, the main gas valve being configured as a diaphragm valve with a drive chamber and a gas outlet chamber, which diaphragm valve is adapted to close or to open due to the spring force of a spring element and a gas outlet pressure which prevails in the gas outlet chamber, counter to a servo pressure which prevails in the drive chamber, and the drive chamber of the safety valve and the drive chamber of the main gas valve being coupled to one another with at least one servo valve being connected in between, the or each servo valve being configured to open in order to enable a gas stream through the safety valve and the main gas valve and to close in order to shut off the gas stream through the safety valve and the main gas valve, and the drive chamber of the main gas valve and the gas outlet chamber being coupled via a line, into which the pressure regulator is connected, the safety valve being adapted to close in a manner which is assisted by the spring force of a spring element and in a manner which is assisted by a servo pressure which prevails in the drive chamber, counter to a gas inlet pressure which prevails in the gas inlet chamber, and to open in a manner which is assisted by the gas inlet pressure which prevails in the gas inlet chamber, counter to the spring force of the spring element and counter to the servo pressure which prevails in the drive chamber, characterized in that the gas inlet chamber and the drive chamber of the safety valve are coupled via a line, into which an orifice is integrated, two servo valves which are configured as three-way valves are connected between the line, via which the gas inlet chamber and the drive chamber of the safety valve are coupled, and the line, via which the drive chamber of the main gas valve and the gas outlet chamber are coupled, namely in such a way that a first three-way valve acts by way of its "Common" and "Normally Opened" connectors on the line, via which the gas inlet chamber and the drive chamber of the safety valve are coupled, namely parallel to the orifice which is integrated into said line, a second three-way valve acts by way of its "Normally Opened" connector on the pressure regulator and by way of its "Common" connector on the line, via which the drive chamber of the main gas valve and the gas outlet chamber are coupled, the two three-way valves are coupled via a line which extends between the "Normally Closed" connectors thereof and into which an orifice is integrated. a first three-way valve acts by way of its "Common" and "Normally Opened" connectors on the line, via which the gas inlet chamber and the drive chamber of the safety valve are coupled, namely parallel to the orifice which is integrated into said line, a second three-way valve acts by way of its "Normally Opened" connector on the pressure regulator and by way of its "Common" connector on the line, via which the drive chamber of the main gas valve and the gas outlet chamber are coupled, the two three-way valves are coupled via a line which extends between the "Normally Closed" connectors thereof and into which an orifice is integrated.
