  • Breakaway connector
    Patent number: 10625068
    Abstract: A breakaway connector generally includes a first valve having a first rotating-type fluid control member, and a second valve that is attachable to the first valve and has a second rotating-type fluid control member. Each of the fluid control members has an open position in which fluid is permitted to flow through the respective valve, and a closed position in which fluid is prevented from flowing through the respective valve. Each one of the valves is configured to engage the fluid control member of the other one of the valves to move the fluid control member from the open position to the closed position upon detachment of the valves from one another.
