ABSTRACT:
A dry break coupling assembly for interconnecting components of a fluid handling system. The coupling assembly includes first and second valves, each includes a rotatable valve element for opening and closing a fluid passageway within a valve body. The over-center clamp mechanism is for interlocking the first and the second valves when the valves are in a connected arrangement, allowing the valves to be easily disconnected when the valves are in a closed position, having a pair of projecting bars disposed on an outer surface of a body of a first valve and a pair of clamp assemblies disposed on a body of the second valve. Each clamp assembly includes a clamp arm having a hook end for engaging one of the projecting bars, and a clamp lever for actuating the hook end to engage or disengage the projecting bar. A yoke assembly is for operatively locking the over-center clamp when the second valve is in an open position, and an automatic locking assembly on each valve for locking the valve into a closed position when they are disconnected.
