Single Protection Valve for Brake Systems - Reliable Air Pressure Safety

Safety single valve is designed to protect the braking system of the car from loss of compressed air in it when supplying other consumers, in particular when supplying compressed air to the braking system of the trailer. If the total pressure drops to a predetermined level due to a leakage failure (e.g. in case of a trailer line break), the single safety valve disconnects the vehicle system from the consumers.

In addition, the valve prevents compressed air from flowing from the consumers (e.g. from the trailer supply line to the tractor brake system).
