Abstract
A plate-like structure comprising a liquid flow path formed in one face thereof, a thin ductile seal-forming coating on the face of the structure which forms the flow path. The structure finds many utilities, most advantageously in constructing a novel valve wherein the disk is flexible and adapted for flexing a central face portion thereof against a conduit, thereby sealing said conduit.
