Abstract

The butterfly valve comprises a valve body consisting of upper and lower halves and having an annular projection formed at an inner peripheral wall for being accepted and held by an annular groove of a valve seat and further including annular end faces disposed so as to engage with corresponding faces of spaced apart conduits when installed between them. A valve seat has an annular groove into which the projection of the valve body is fitted, and includes an external peripheral surface which fits to an internal peripheral surface of the valve body and further includes a seat surface formed at an internal peripheral surface.
