Abstract
Improvements in the valves for liquids that are characterized in making the body or housing of the valve with hollow cylindrical shape with a tubulura for the entrance of the liquid and a wide exit mouth aligned with that, installing inside this body, a cylindrical rotating part and axially displaceable, which is endowed at its upper end with a rotating bushing, in turn provided with a flat and elastic piece that constitutes the shutter itself, which is applied, when moving upward to the inner part, on a flange It is important that the inlet duct has been provided when it opens into the body, which thus constitutes a valve seat, with the installation of the internal cylinder with hard friction that allows it to be stable in any position without the hydraulic pressure being able to vary it, providing it with a drive handle and a propeller pitch system that rotates in either direction Axially inside the body.
