Improvements in the sealed butterfly valves, characterized by the fact that the internal diameter of the valve body that the butterfly is intended to seal is provided with a sleeve, flexible and elastic material that has two diametrically opposed holes for the passage of the control rod of the butterfly and of smaller diameter, said sleeve having a diametrically sensitive section in the shape of a U, whose ends are forced by the tightening of the flanges, in the circular grooves provided for this purpose on the contact surfaces of said body with the flanges, resulting in a deformation of the sleeve in the form of a flange or convexity flange directed to the center of the internal diameter and a compression of the sleeve, which provide a tightness: a) around the disk, in closed position by elastic deformation of the sleeve, in contact with the disk; b) around the control rod, in two paths of the sleeve; c) between the body and the connection flanges, by crushing the U arms of the sleeve, between the valve body and the flanges.
