Valve for inflating and deflating inflatable articles, completely coated with rubber or other similar material, so that it can be vulcanized or otherwise sealed to the inflatable article. Systems are also provided for allowing fast deflation of the inflatable article, either by reason of applying and securing a tongue provided at the end of the valve plug; or by pressing and rotating the valve closure member such that projections or tabs provided on said closure member engage with the valve body whereby the valve remains open until the tabs are returned to recesses provided in the valve body.
