A0044298044 Compatible Relay Valve for Mercedes-Benz

What does a relay valve do?

This relay valve plays a critical role in the compressed air brake system by managing air pressure distribution to ensure consistent braking performance. Built with high-strength components, it provides reliable operation under heavy-duty conditions by facilitating rapid air pressure transfer triggered by pilot signals.

Compatibility and vehicle fitment

The component is designed for use in Mercedes-Benz heavy commercial vehicles. This part is compatible with Mercedes-Benz systems and ensures precise control within the pneumatic circuit.

Installation and maintenance

Installation requires careful attention to the M22x1.5 VOSS and M16x1.5 VOSS port connections to prevent leaks. Technicians should verify that the maximum operating pressure of 8.5 bar is not exceeded during system testing to maintain component longevity.

Operational guidance

Regular inspection of the silencer and port seals is recommended during routine maintenance to ensure optimal pneumatic response and prevent air loss within the braking system.

OE cross-reference
