301.02.0071 Compatible Air Dryer Valve — Volvo & Renault

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic braking system by managing air quality and pressure regulation. Designed with high-strength components, it ensures the continuous removal of moisture and contaminants from the air supply to prevent system corrosion and component wear.

Vehicle and engine compatibility

The valve is specifically engineered for heavy commercial vehicles, including Volvo models such as the FH12, FH13, FM series, and VNL, as well as Mack Granite and Pinnacle trucks. It is also compatible with Renault Trucks models like the Kerax and Premium. This component is also fitted to DAF trucks.

Technical specifications and installation

For optimal performance, technicians should verify the port configurations during installation. This unit features M22x1,5, M12x1,5, and M16x1,5 port sizes and operates at a standard 24 V with a maximum pressure of 13 Bar. Regular inspection of the valve assembly helps maintain system integrity.

System maintenance guidance

Maintaining a clean air supply is essential for the longevity of the entire braking system. Replacing worn valves prevents pneumatic failures in demanding transport environments. Consult your authorized distributor.
