Instantaneous closing valve, characterized essentially by the fact of being constituted by a tabular body through which the liquid circulates, and perpendicular to it and passing through a hollow cylinder with a hole in its center; a valve housed inside the cylinder that it blocks, and provided with a diametral narrowing existing in its central part; actuating buttons existing at the ends of said valve, and because when the diametral narrowing coincides with the drill, the liquid is passed, and also because there are two extreme scraped areas for easy coupling to conduits or consumer devices.
