ABSTRACT:
A butterfly valve for pipes having smooth ends comprising a body constituted by a metal casing of generally tubular shape with two dimensional bosses provided with coaxial passages. A layer of elastomer material externally and internally envelops the totality of the metal casing. Two shafts are rotatably mounted in the coaxial passages and support a butterfly within the body. The body includes at one of the extremities thereof an end portion which permits connection of the valve to a pipe by interfitting thereof. The other end of the body can be connected in various ways with the other pipe either as a male or a female fitting with associated annular lips.
