Description

What does a levelling valve do?

This levelling valve serves as a critical component within the air suspension system, regulating pneumatic airflow to maintain optimal vehicle height. By utilizing a mechanical lever movement, it compensates for load variations to ensure the chassis remains level during operation. Built with high-strength components, it is designed to withstand the rigorous demands of heavy commercial vehicle service.

Vehicle compatibility and application

The component is compatible with Mercedes-Benz and DAF trucks. Its specific design ensures seamless integration within the air bellows control system of these vehicle models. This ensures consistent stability across various load conditions for the chassis.

Installation and maintenance

Installation requires careful attention to the M12x1,5 port connections and the 90 mm lever positioning. Technicians should verify the 6.2 mm lever opening during assembly to ensure correct pneumatic response. Maintaining clean connection points is essential for long-term reliability in heavy-duty environments.

Troubleshooting and selection

Monitoring the lever movement can help identify potential issues in the suspension height control. Regular inspections of the mounting points and pneumatic lines are recommended to prevent uneven loading or air leaks in the system.
