Abstract
A segmented pipe coupling provides a housing for a butterfly valve, and preferably is provided with oppositely angled end faces of saw tooth configuration at the respective ends of the coupling segments, thus allowing the inclined end faces to emerge at the axial end faces of the coupling at or closely adjacent to the X-Z plane of an axially long coupling. A slow motion rotary drive for the butterfly valve also is provided.
