ABSTRACT OF THE DISCLOSURE A butterfly valve assembly is disclosed having a resilient seat to compensate for wear. The valve has a rigid body with opposing end surfaces adapted to mate with opposing flanges. The body has opposing internal end surfaces spaced inwards from and having a smaller diameter than the external parallel end surfaces, a flexible ring within the annular body is adapted to deform under uneven stresses but to return to its original shape when the stresses are released. An annular seat of elastomeric material supports the flexible ring in a flexible relationship within the body to form a seat assembly leaving an annular space between an external surface of the seat assembly and an internal surface of the body. The seat assembly has two external flanges, one at each end which overlap the internal end surfaces and are adapted to be clamped between the internal end surfaces and the opposing flanges. A valve closure member is rotatably mounted to the body within the seat assembly adapted to seal with an internal surface of the annular seat and thus closes the valve.
