Description

What does a levelling valve do?

This levelling valve plays a critical role in maintaining the correct ride height of air suspension systems. By responding to changes in vehicle load, it regulates air pressure within the suspension bellows to ensure the chassis remains level during operation in heavy commercial vehicle service.

Scania vehicle compatibility

Specifically engineered for Scania trucks, this component ensures stable performance under varying load conditions. The unit features a 175 mm lever with a 6 mm opening and M12x1.5 threaded ports to ensure precise movement and reliable air distribution within the suspension system.

Installation and maintenance

For workshop technicians, proper installation is vital to ensure the 175 mm lever operates freely without obstruction. Checking the M12x1.5 port connections during routine maintenance helps prevent air leaks and ensures the suspension maintains its intended geometry.

Troubleshooting suspension stability

Regular inspection of the lever movement can help identify early signs of wear before system instability occurs. Consult your authorized distributor for further assistance.
