Abstract

Improvements in the construction of off-center butterfly valves, of the type in which the sealing gasket is constituted by a sleeve having at least one bead in one piece with it and in radial projection towards the butterfly, characterized by the fact of providing in said sleeve two end collars whose end surface comprises an internal area that emerges with the end portion of the valve body, and a peripheral area which, in a free state, that is to say before the assembly of the valve in a conduit, delimits a projection axial with respect to this section.
