A valve unit for controlling the delivery of a combustible gas through a gas path comprises a first valve seat in the gas path and a first closure means associated with the seat, a first actuator means for the control of the closure means for opening and closing of the valve seat and also motor means for the operating control of the first actuator means. The unit further comprises a second electromagnetic actuator means interposed between the closure means and the first actuator means to urge the closure means so as to close the valve seat, independently of the operating position of the first actuator means, when a predetermined condition occurs which requires the interception of the valve seat.
