ABSTRACT:
A breakaway safety valve comprising interengageable plug and socket components having a fluid flow passage therethrough, and a plurality of breakaway members holding the plug and socket components in assembly. The breakaway members are adapted to break when the valve is subjected to a force of predetermined magnitude tending to pull the plug and socket components apart thereby to permit separation of the components without damage thereto. At the time of separation, a valve member in the flow passage automatically closes to cut off fluid flow through the passage.
