Improved valve for aeration ducts, characterized in that it is constituted in a one-piece body made of synthetic material, plug-in on a mouth or conduit of an aeration installation, inside which there is a transversal element of flexible laminar material attached to said body by means of an internal radial appendage of stepped configuration, selectively sectionable by portions that, depending on their unseparated length, gives the sheet a greater or lesser degree of freedom in flexion, in order to offer different resistances to the air flow that can, of this way to be regulated in its flow.
