Relay Valves

Relay valves are critical components within automotive air brake systems, found in both passenger cars and commercial vehicles. Positioned between the brake pedal and the air brake chambers, these valves amplify the driver's signal to apply the brakes consistently across all wheel positions. They modulate air pressure to ensure proportionate braking force, enhancing both safety and control. Relay valves are especially common in larger vehicles like trucks and buses that utilize air brake technology. Examples in our selection include Wabco relay valves, as well as specific MAN parts such as MPN 51158015173 and 81.51201-0416. These valves feature robust construction for reliable performance under demanding conditions and are vital for maintaining optimal braking efficiency.
