Description
What does a levelling valve do?
This levelling valve plays a critical role in maintaining the correct ride height and stability within heavy commercial vehicle suspension systems. By regulating air pressure distribution, it ensures that the chassis remains level under varying load conditions, protecting the structural integrity of the suspension components.System compatibility and fitment
This component is designed for use in systems compatible with Knorr-Bremse. It features specific port dimensions including M12x1,5 and M16x1,5 connections to ensure precise fitment within the pneumatic circuit of the vehicle's suspension assembly.Installation and maintenance
For proper installation, technicians should verify that all port connections are clean and that the seals are seated correctly. This valve is rated for a maximum operating pressure of 10 BAR. Regular inspection of the air lines and connection points is recommended to ensure optimal performance during operation.Performance and troubleshooting
Maintaining a stable suspension level is vital for preventing uneven tire wear and ensuring predictable handling. If the vehicle exhibits uneven leaning or inconsistent ride height, checking this valve as part of a comprehensive suspension system audit is advised.OE cross-reference
303.07.0025 (Levelling Valve) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number SV1281.Technical Specifications
