ABSTRACT:
A modular butterfly valve includes a disc member which is adapted for selective rotation between an open and a closed position, a housing, a resilient valve seat, and a clamping ring which are held together by a hinged quick coupling ring. The disc member is resiliently suspended by the valve seat which provides a self-centering of the disc member in a direction transverse to a direction of material flow. This butterfly valve further includes at least one means for limiting the displacement of the disc member in a direction which is parallel to the direction of material flow when loads are placed thereon.
