A Tractor Air Brake Lines Relay Valve can activate the emergency brakes on the trailer in the event of a sudden loss of air pressure in the brake system, helping to bring the carrier to a stop safely. It helps maintain balance and control during braking by ensuring that the braking force is evenly distributed between the tractor and trailer axles, improving overall stability.Attributes:• Prevent skidding and ensure a smooth and coordinated braking operation• Protect the air brake system from over-pressurization or rapid pressure dropsApplications:A Tractor Air Brake Lines Relay Valve controls the flow and distribution of compressed air between the tractor and trailer brake systems, regulating brake pressure to ensure effective braking performance.
