An improved valve, characterized essentially by the fact of comprising: a valve body, whose interior or chamber communicates with the outside by a lower passage or exit mouth, and by a lateral tubular extension or entrance mouth, because in the part upper part of said valve body is fixed a cover with a hole in its central area where an elbow tubular element is fitted, whose free end is housed in turn in a tubular terminal in "T", through which runs a plunger, to which displaces the action of a float, and because inside the valve body a piston is housed whose rod has a flat sealing gasket at its lower end, and also because when opening the first mentioned piston the output step of the tubular element causes a depression in the chamber, followed by the consequent opening of the outlet mouth by displacement of the plunger, and by being the top and bottom of the chamber communicated with each other by a tubular passage existing on one side of the valve body and provided with a regulating screw.
