Description

What does a levelling valve do?

This levelling valve plays a critical role in maintaining the correct ride height of heavy commercial vehicle suspension systems. By regulating pneumatic pressure, it ensures the vehicle remains stable and level under varying loads, protecting the chassis and suspension components from uneven wear.

System compatibility

The component is designed to be compatible with Knorr-Bremse systems. This ensures reliable performance and precise calibration within the pneumatic circuit of the vehicle's suspension assembly.

Installation and maintenance

Installation requires careful attention to the M12x1,5 port connections and the 178 mm lever positioning to ensure accurate leveling. Technicians should verify that the system pressure does not exceed the 10 BAR operating limit during testing to maintain component integrity.

Troubleshooting and inspection

Regular inspection of the inner hole diameter and port seals is recommended to prevent air leaks or improper leveling response.

OE cross-reference
