Improvements in hand-reducing devices for gases, characterized by the arrangement inside the valve body and the mouth of the gas passage, when opening into the greater space in which the valve runs, of a frustoconical projection as a nozzle, so that its opening or orifice can be closed by a soft mass such as rubber, or another housed in the end or end of the sliding stem that makes up the valve in such a way that when moving said valve longitudinally, actuated by the lever, moved in turn by the membrane, contact the white mass with the nozzle and make a perfect seal without leaks.
