Abstract : A pipe-coupling assembly includes a radially-extending ring-shaped member carrying in flow-controlling valve plate. Ring-supporting members press flushly against both sides to operatively mount the ring and its valve plate in the conduit. Non-reversibility is achieved by forming a lateral flange on side ony of the ring member and a mating groove in one only of its support members. Correct mounting requires the mating of the flange and groove. (Author)
