Pneumatic head for membrane valves, normally open, characterized in that it comprises a diaphragm that divides the head into two chambers, the upper one being sealed and provided with an intake nozzle of the motor fluid, whose diaphragm is fixed to an axis that governs the carrier shoe of the membrane that opens and closes the passage of circulating fluid through the valve body; the diaphragm is required by the tension of a compression spring that at rest keeps the valve normally open, while, on the other hand, when the upper chamber of the head receives an excess pressure determined by means of the motor fluid, the diaphragm moves compressing the spring at the same time that the steering shaft descends pushing the closing membrane on its seat.
