ABSTRACT:
A pipe-coupling assembly includes a radially-extending ring-shaped member rrying a flow-controlling valve plate. Ring-supporting members press flushly against both sides to operatively mount the ring member and its valve plate in the conduit. Non-reversibility is achieved by forming a lateral flange on one side only 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.
