The rotary gas tap (1) with an electromagnetic safety valve (3), is of the conical regulation member (7) type, and the electromagnetic actuator (3a), being of a smaller power and size, is built entirely into a pipe housing (2a) in the body of the tap. The valve actuator (3a) is of the type where the seal member (9) is lifted by means of a DC voltage. The cylindrical magnetic frame (14) penetrating into the coil (15) is guided inside it, and a magnetic capsule (16) surrounding the coil is of a diameter Dh of around 14 mm, adjusted to that of the housing (8) in the body of the tap (2a). The stroke “R” of the seal member (9) corresponds to a gap (G) greater than 2.5 mm, reaching a sizeable passage opening “A” in the valve (9,10) necessary for a maximum inlet flow (Q) in the tap. At the same time the electromagnetic actuator (3a) is of low power, by means of a low reluctance in the magnetic circuit (13-16), although the diameter “Da” of the cylindrical frame is restricted to less than 4 mm.
