New valve for inflatable articles, characterized by the fact that the tube of two superimposed diameters of which this type of valves are made, has very thick walls in relation to its height in order to avoid the dilatations produced when yielding the sheet material, elastic, property of the polyvinyl chloride, upon receiving the internal pressure of the swollen body, increasing the effect of the non-dilation provided by the re-thickening effected, by means of a curb placed on the outside of the mouth of said valve, while the Walloon for the union, by electronic welding, although being thicker than the current, continues, however, with its laminar condition.
