Valve for balloons and the like, characterized by being constituted by two conjugated pieces, consisting of a tubular body whose axial through bore has an area with internal thread followed by a throttle that ends in a chamfer or truncated-conical seat that is continued in a conduit a straight end with a diameter that is slightly smaller than that corresponding to the upper threaded area, while at the same time that outside and below it has a series of circular incisions or grooves that provide a better grip on the vulcanized set of this piece with the balloon material itself, while the second part comprises the obturator, itself, which runs through the interior of the axial through-hole through an external thread of its upper area that also has a throat, for application of a driving screwdriver, in conjunction with a head with collar on which a sealing gasket with slot for air passage is mounted e, which, when set against the truncated-conical chamfer, produces the perfect sealing of the valve.
