The main purpose of a tractor protection valve is to protect the trailer air supply in the event of a separation between the tractor and trailer. It is designed to automatically close and stop the air supply to the trailer's brakes in case of a detachment. This helps prevent the trailer from braking uncontrollably and causing a potential accident.
