Improvements in the manufacture of passage valves, according to which a main body is provided, provided with a cylindrical cavity, in which two upper ducts are opened, converging towards an end emptying provided in a projecting body, of orthogonal axis to the said cavity, which constitutes the element through which the hermetic coupling of the assembly to the bottom of the corresponding reservoir and a lower conduit extending in an axial direction along a fitting, through which it can be carried out, can be carried out. the coupling to the valve of a corresponding flexible pipe of fluid conduit is carried out, having provided inside the expressed cavity an axis, arranged so that it can rotate freely between certain limit positions determined by a set of appropriate stops, to whose axis a sealing body of elastic material and section in arc of a circle, which adjusts and is compressed with the walls of the expressed cavity, and whose position determines the circulation of fluid between one or the other of the two upper conduits and the lower conduit, or the obturation of both conduits, preventing this circulation.
