Description

What does a levelling valve do?

This levelling valve serves as a critical component within the air suspension system of heavy commercial vehicles. By regulating air pressure based on load changes, it maintains the appropriate ride height and ensures stable vehicle dynamics during transit. This high-strength component is designed to withstand the rigorous operating conditions typical of heavy-duty transport.

Vehicle compatibility and fitment

This specific unit is designed for use in Scania trucks and related heavy commercial vehicle applications. It functions seamlessly within the existing pneumatic architecture to provide consistent leveling performance across various load capacities.

Installation and maintenance

Installation requires careful attention to the M12x1.5 port connections to ensure an airtight seal. Technicians should verify that the 175 mm lever has sufficient clearance for its 6 mm opening range during operation to prevent mechanical interference within the suspension assembly.

System maintenance guidance

Regular inspection of the lever movement and port seals can help prevent premature system failure or uneven chassis height.

OE cross-reference

303.07.0003 (Levelling Valve) is the equivalent of the Scania OE number. This part directly replaces Scania OE number 677279.
