Improved valve, characterized by consisting of a hollow body, cylindrical inside, crossed by a normal axis to the revolution of the cylinder and actionable from the outside, to which axis is fixed a butterfly as a dish concentric with the inner cylindrical surface of the body which can rotate along an arc of approximately 90º moved from the end of the axis to which it is fixed, and said arc is limited by two positions, one of which is achieved by the existence of adequate stops in the body itself, and corresponds to the opening of the valve, and the other takes place when the edges of the saucer or butterfly come into contact with an elastic gasket housed in a groove internal to the cylindrical body and coaxial with it, so that the part of the butterfly that is located on one side of the axis of rotation comes into contact with the elastic joint on the opposite edge, anterior or posterior, that the butterfly part that remains on the other side of said axis of turn.
