The invention relates to an integrated gas regulating and safety valve for burners of a modulatable gas heating device. According to the invention, the gas regulating and safety valve comprises a housing () with two controllable closing elements, the axes of which are spaced apart from each other and extend one behind the other in series in the direction of gas flow between an inlet channel () and an outlet channel () of the housing. In the de-energized state, the two closing elements abruptly close the gas regulating and safety valve independently of each other, in each case by means of an associated spring element (). The first closing element, additionally serving for the modulation of the gas stream, has a drive spindle (), which is formed as a spindle of a stepping motor (), is surrounded by an excitation winding () and has placed on its end a restrictor component () and, at a distance from that, the first spring element (). The second closing element, on the other hand, has a closure component () connected to an armature (), wherein the armature () is arranged in a cylindrical cavity () and operates against the force of the second spring element () acting on the armature (). This cavity () is surrounded by an excitation winding () of the armature () that is formed as part of an electromagnet.
