ABSTRACT:
A modular butterfly valve includes a disc member which is selectively rotated between an open and a closed position, a housing, a resilient valve seat, and a clamping ring which are held together by a hinged coupling ring. The disc member is resiliently suspended in this valve by the valve seat, which provides for a self-centering of the disc-member. The hinged coupling ring may include an integral actuation means which is keyed into alignment during assembly. This modular butterfly valve assembly is adapted for being attached to an adjacent apparatus by a quick coupling means.
