ABSTRACT:
A dual disk valve system which may be quickly, easily and inexpensively repaired. The system comprises (i) a central conduit, (ii) a pair of end conduits securely yet detachably coupled to each end of the central conduit to form a single continuous conduit, (iii) a bearing ring, constructed of a pliable material, occupying an inner annular cavity at the junction of each of the end conduits with the central conduit, and (iv) a rotatable disk valve at the junction of the end conduits and the central conduit which may be rotatably or sealingly engaged against the bearing ring to prevent flow therethrough.
Normal wear of the system is limited to the bearing rings which may be quickly, easily and inexpensively replaced by separating the central and end conduits.
