Description
What does a levelling valve do?
This levelling valve plays a critical role in maintaining the correct ride height and stability within the vehicle suspension system. By regulating air pressure, it ensures that the heavy commercial vehicle remains level under varying load conditions, providing optimal driving stability and safety.System compatibility and fitment
This component is compatible with Knorr-Bremse systems. It is engineered to meet the rigorous demands of heavy commercial vehicle service, ensuring reliable performance in demanding environments.Installation and maintenance
The unit is specified with M12x1.5 threading on both Port 21 and Port 11 to ensure precise integration into existing pneumatic lines. For proper installation, technicians should verify the 12 BAR pressure rating and inspect the Ø 2.30 mm inner hole clearance during assembly to prevent system leaks.Troubleshooting guidance
Regular inspection of suspension valves is recommended to prevent uneven loading or chassis tilt. If the suspension fails to level correctly, check the valve for debris or mechanical blockage in the pneumatic circuit.OE cross-reference
