Description

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by managing air quality and protecting downstream components. By effectively handling pressure and moisture, it ensures the reliability of the entire braking circuit during heavy-duty operations.

Technical specifications and fitment

This component is compatible with Knorr-Bremse systems and is engineered to meet rigorous technical requirements. It features specialized port sizes such as M22x1,5, M16x1,5, and M12x1,5, along with a Ø20,5 connection to ensure precise fitment within the air management assembly.

Installation and maintenance guidance

For workshop technicians performing maintenance, verifying the port configurations like the M22x1,5 VOSS connection is essential for correct installation. Maintaining proper pressure levels around 12,3 BAR helps prevent system corrosion and ensures consistent pneumatic performance throughout the service interval.

System reliability and selection

Regular inspection of the valve helps prevent contaminants from entering the braking lines. Choosing high-strength components ensures long-term reliability for heavy commercial vehicles in demanding service environments. Consult your authorized distributor.
