Abstract

Improvements in butterfly valves characterized by comprising a valve body with a current passage inside it, and an annular recess around the mentioned passage, a closure element pivotally mounted on the valve body, with its axis of rotation prolonged through of the longitudinal axis of the current passage, and off-center with respect to the recess, a seat ring mounted on the recess, to be able to carry out radial movement, in order to accept, as an interference fit, a part of the periphery of the closure element, to thereby interrupt the flow of current, and a sealing ring mounted between the adjacent walls of the seat ring and the recess, to close a continuity solution between said ring, and the recess, without preventing radial movement of the ring of seat in the recess.
