Abstract
A ball valve connector of the frangible crashworthy type wherein two fluid flow connector body halves are interconnected by fracturable elements. Each body half includes a ball valve within a flow passage pivotally mounted on diametrically located pins. The pivot pins and valves are capable of displacement in the axial direction of fluid flow to compensate for manufacturing tolerances and provide maximum sealing characteristics. Each valve is rotatable 90.degree. between open and closed positions, and a stop projection defined on each valve cooperates with a spring biased stop ring providing positive retention of the valve in the closed position.
