The purpose of a breakaway valve in a motor vehicle fueling hose is to separate with minimal spillage during excessive pulling. These valves are designed to detach from the fueling nozzle if a vehicle drives away while still connected to the fueling station. This mechanism helps to prevent spills and potential hazards that could arise from the fuel being released into the environment during such incidents. The design ensures that the connection is interrupted safely and effectively, minimizing the risk of accidents and promoting safety at fueling stations.
