Description

What does a relay valve do?

This relay valve serves as a critical component within the pneumatic brake system, managing air pressure distribution to ensure consistent braking force. Built with heavy-duty grade materials, it is designed to withstand the high-pressure demands of heavy commercial vehicle operations.

Vehicle compatibility

This specific unit is compatible with MAN vehicles and is engineered to meet strict industrial standards. It ensures precise signal transmission within the air brake circuit, maintaining system stability during deceleration.

Installation and maintenance

Installation requires careful attention to the M22x1,5 VOSS and M16x1,5 VOSS port connections. Technicians should verify that the maximum pressure does not exceed 10 BAR and check all connections for air leaks during assembly to ensure optimal brake performance.

System reliability

Regular inspection of the pneumatic lines and valve ports is recommended to prevent pressure drops. Proper maintenance of these components ensures the continued reliability of the vehicle's braking system under heavy loads.

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 81521169067.
