980829 Compatible Air Dryer Valve

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by regulating air pressure and removing moisture from the air lines. By ensuring that contaminants are purged, it prevents corrosion and protects downstream components from freezing or sticking, which is vital for maintaining consistent braking performance in heavy commercial vehicles.

Vehicle compatibility and technical specifications

This specific component is designed for Irisbus vehicles. It operates with a 24V heater to prevent moisture buildup during cold conditions and features specific port dimensions including M22x1,5 and M12x1,5 to ensure precise integration into the existing pneumatic circuit.

Installation and maintenance guidance

For optimal performance, technicians should verify the port sizes and electrical connections during installation. Regular inspection of the valve helps prevent air leaks and ensures that the purging cycle functions correctly under operating pressures of 8,1 BAR. Consult your authorized distributor.

System reliability

Proper maintenance of this valve helps extend the service life of the entire brake system by keeping the air supply clean and dry.
