Description

What does a relay valve do?

This relay valve plays a critical role in the pneumatic brake system by managing air pressure signals to ensure precise braking response. Built with high-strength components, it maintains consistent pressure regulation even under heavy commercial vehicle operating conditions.

Vehicle compatibility

This specific unit is engineered for MAN vehicles and is compatible with MAN systems. It ensures seamless integration within the existing pneumatic architecture of the braking circuit.

Installation and maintenance

Installation requires careful attention to the port connections, which include M22x1.5 VOSS and M16x1.5 VOSS threading. Technicians should verify that all connections are secure and that the system does not exceed the 10 BAR maximum pressure rating during testing.

System maintenance

Regular inspection of the valve ports and seals is recommended to prevent air leaks. Maintaining proper pneumatic integrity ensures the continued safety and efficiency of the heavy commercial vehicle braking system.

OE cross-reference

303.01.0003 (Relay Valve Relay Valves) is the equivalent of the MAN OE number. This part directly replaces MAN OE number 81521166069.
