405674 Levelling Valve for Scania Trucks

What does a levelling valve do?

This levelling valve plays a critical role in maintaining the correct ride height of air-suspended heavy commercial vehicles. By regulating air pressure within the suspension system, it ensures the vehicle remains level under varying load conditions, providing stability and safety for the chassis and cargo.

Vehicle compatibility and fitment

This component is specifically designed to be compatible with Scania vehicles. It maintains precise control within the suspension system through its high-strength components and specialized port configuration.

Installation and maintenance

Installation requires attention to the M12x1,5 port connections to ensure a secure seal. Technicians should verify that the system pressure does not exceed the 10 BAR rating and check the inner hole diameter of 21 / Ø 1,80 during assembly to ensure proper air flow and leveling accuracy.

Troubleshooting guidance

Regular inspection of the suspension valves can prevent uneven wear on tires and chassis components. If the vehicle exhibits uneven leaning or inconsistent ride height, consult your authorized distributor.
