摘要： The present invention is directed to a self-sealing breakaway valve having a poppet-style design. The breakaway valve may be made from two body portions coupled together by one or more frangible fasteners in order to form a flow path through the breakaway valve. Each body portion may include a valve mechanism responsive to separation of the two body portions from each other to cause closure of the flow path in the respective body portion. The valve mechanisms may be releasably coupled together by a coupling key configured to restrict movement of each valve mechanism, so that the flow path within the breakaway valve remains open. Upon separation of the two body portions from each other, the coupling key may be released from the valve mechanisms allowing for closure of the flow path by the valve mechanisms thereby preventing fluid leakage from the breakaway valve.
