002 429 84 44 Relay Valve for Mercedes-Benz Trucks

What does a relay valve do?

This relay valve plays a critical role in the compressed air brake system of heavy commercial vehicles by facilitating rapid air pressure transfer triggered by a pilot signal. Built with high-strength components, it ensures the necessary response time for braking performance and maintains system integrity under heavy-duty operating conditions.

Vehicle compatibility

This component is specifically compatible with Mercedes-Benz trucks and heavy commercial vehicle systems. It is engineered to meet the rigorous demands of professional fleet maintenance and workshop service requirements.

Installation and maintenance

Installation should be performed by a qualified technician to ensure correct mounting on the chassis between the main air reservoir and the brake chambers. This unit features M22x1.5, M16x1.5, and M16x1.5 port sizes, operating at a maximum pressure of 8 BAR to maintain optimal pneumatic performance.

System performance

Regular inspection of the pneumatic connections and port seals is recommended to prevent air leaks and maintain consistent braking response times across the vehicle's air brake system.
