301.03.0020 Complete Air Dryer Valve — DAF

This high-strength component serves as a critical element within the pneumatic braking system, specifically functioning as a complete air dryer valve assembly. Designed to manage air quality and pressure stability, it ensures the long-term reliability of the vehicle's air supply through its robust construction and precise port dimensions.

301.03.0020 is the OE-equivalent of the DAF ACHE007 and the KNORR-BREMSE II30182, II30182AT, II30182N50, and LA 8224 parts used in heavy commercial vehicle brake systems. This part is engineered to meet strict technical standards for compatibility with DAF and KNORR-BREMSE hardware architectures.

The assembly features a 24 V heater and specific port configurations including Port 1 (M22x1,5), Port 21 (M22x1,5), Port 22 (M12x1,5), and Port 4/23 (M12x1,5) to ensure seamless integration during maintenance or replacement. Workshop technicians should verify the pressure stability of 8,4 BAR during installation to maintain optimal system performance.

Regular inspection of the air dryer valve components is essential for maintaining braking efficiency in heavy commercial vehicles. Ensuring the correct port threading and electrical connection for the 24 V heater will prevent pneumatic leaks and system downtime.
