I98289 Compatible Levelling Valve

What does a levelling valve do?

This levelling valve plays a critical role in the air suspension system of heavy commercial vehicles. By regulating air pressure within the bellows, it maintains a constant ride height and ensures the vehicle remains level regardless of the load weight. It is constructed from high-strength components to withstand the rigorous operating conditions of the suspension system.

Compatibility and technical specifications

The component is compatible with Knorr-Bremse systems and is designed for heavy commercial vehicle applications including trucks and buses. This specific unit features a lever diameter range of Ø 6 - 315 mm and multiple port connections (M12x1.5 and M16x1.5) to ensure precise integration into existing pneumatic lines.

Installation and maintenance guidance

For proper maintenance, technicians should inspect the lever movement and port integrity during every suspension service. Ensuring that the operating pressure does not exceed the 13 BAR limit is essential for preventing premature wear of the internal seals and maintaining system stability.

System stability and troubleshooting

When replacing this unit, verify that all port threads are free of debris to prevent air leaks. Maintaining correct pneumatic pressure levels within the system helps ensure the longevity of the entire suspension assembly.
