Description
What does a levelling valve do?
This levelling valve plays a critical role in maintaining the correct ride height within the pneumatic suspension system. By regulating air pressure based on the vehicle's load, it ensures stable driving dynamics and prevents uneven weight distribution across the axles.Compatibility and application
Designed for heavy commercial vehicle applications, this component is compatible with Knorr-Bremse systems. It operates effectively under pressures up to 10 BAR, providing reliable performance for fleet managers and workshop technicians during demanding service intervals.Technical specifications and installation
The unit features M12x1.5 port specifications and a lever diameter range of Ø 6 - 180 mm to ensure precise mechanical feedback. During installation, technicians should verify that the M12x1.5 (x2) ports are properly seated to prevent air leaks in the pneumatic circuit.Maintenance and troubleshooting
Regular inspection of the lever movement and port integrity is recommended to prevent suspension sagging. Maintaining these high-strength components ensures the longevity of the entire pneumatic suspension assembly.OE cross-reference
