85 50001 4712 MAN Compatible Levelling Valve

What does a levelling valve do?

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

Compatibility and application

This component is specifically engineered for MAN trucks. It operates effectively within the pneumatic suspension system to compensate for weight changes and road irregularities. The design ensures high-strength performance during continuous operation in demanding environments.

Technical specifications and installation

The unit is specified with M12x1.5 port sizes (Ports 1, 4, and two ports at 21) and is rated for a maximum pressure of 10 BAR. For proper installation, technicians should verify the inner hole diameter of 21 / Ø 1.80 and ensure all connections are secure to prevent pneumatic leaks.

Maintenance guidance

Regular inspection of the suspension linkage and valve movement is recommended to prevent uneven wear on tires or chassis components. Consult your authorized distributor.
