What does a levelling valve do?

This levelling valve serves as a critical component within the air suspension system, regulating the pneumatic airflow to maintain consistent vehicle height. By responding to chassis movement, it ensures the air bellows are properly balanced under varying load conditions, providing stability for heavy commercial vehicles.

Compatible Volvo models and engines

This component is compatible with a wide range of Volvo models including the F10, F12, FH12, FH16, FL10, FL12, FM10, FM12, NH12, NL10, NL12, VHD, VNL, B10B, B10M, and B12. It is suitable for various engine types such as TD102, TD122, D12C, D16C, D10A, and D12A.

Technical specifications and installation

The unit features specific technical specifications including M12x1,5 port sizes (Port 1, Port 4, and Port 21) and an operating pressure of 10 BAR. The internal hole diameter is 21 / Ø 1,80. For proper installation, technicians should ensure all pneumatic connections are secure and the system is free of contaminants to maintain optimal performance.

Maintenance and troubleshooting

Maintaining the air suspension system involves regular checks of the valve linkage and seals to prevent pressure loss. If height inconsistencies occur during operation, inspecting this component is a recommended step in troubleshooting suspension instability.
