301.02.0041 Air Dryer Valve for DAF MAN Scania

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by managing air flow and moisture separation. Built with high-strength components, it helps prevent contamination within the air circuit, ensuring the longevity of downstream pneumatic components. It is essential for maintaining consistent pressure levels during braking operations.

Vehicle compatibility and fitment

This component is compatible with DAF, Faun, MAN, Neoplan, and Scania vehicles. It also serves as an OE-equivalent part for various heavy-duty applications where reliable air regulation is required. The valve is designed to meet stringent industry standards for fitment and performance.

Installation and maintenance

Technicians should verify the port sizes—specifically the M22x1,5 and M12x1,5 connections—before installation to ensure a precise seal. Regular inspection of the valve's operation at 8.1 BAR is recommended to prevent moisture buildup or pressure drops in the braking system. Consult your authorized distributor for installation guidance.

Troubleshooting guidance

If the system experiences moisture accumulation or irregular pressure fluctuations, this valve should be inspected as part of a comprehensive pneumatic system check.
