339792 Levelling Valve for Scania Trucks

What does a levelling valve do?

This levelling valve plays a critical role in maintaining the correct ride height within the air suspension system of heavy commercial vehicles. By regulating air pressure distribution, it ensures that the vehicle remains stable and balanced under varying loads, protecting the chassis and ensuring optimal driving dynamics.

Compatibility and specifications

Specifically designed for Scania vehicles, this component is engineered to meet rigorous service requirements. It operates effectively within a maximum pressure range of up to 13 bar and features a lever diameter ranging from Ø 6 to 315 mm to ensure precise movement and responsiveness.

Installation and maintenance

For professional workshop technicians, proper installation is vital to maintain system integrity. This valve features M12x1,5 port sizes (Port 1, Port 21, and Port 22) to ensure a secure connection. Regular inspection of the lever movement and port seals is recommended during routine suspension maintenance to prevent pressure leaks.

System performance

When replacing components in the pneumatic suspension system, ensuring exact compatibility with existing hardware is essential for preventing uneven load distribution across the axles.
