Perfected valve, for inflatable bodies, characterized essentially by the fact of being constituted by an internal cylindrical body, whose inner surface presents practiced grooves, being traversed by a hole for injection of air, capable of allowing the introduction of a flexible core of light greater diameter than the cylindrical body itself, whose adjustment under pressure in this determines the simultaneous adaptation of the core to the grooves and establishes a closure of great consistency, complemented by the top that exerts on the upper zone of the core an annular rim that limits the hole provided in the spherical surface itself.
