301.03.0019 DAF Compatible Complete, Air Dryer Valve

This complete air dryer valve is an essential component within the pneumatic brake system, designed to manage moisture and maintain optimal air quality for heavy commercial vehicle operations. Built with high-strength components, it ensures the stability of the air supply under demanding service conditions.

301.03.0019 is the OE-equivalent of the DAF ACU8494, ACU8494A, ACU8494R and the KNORR-BREMSE II30178, II30178AT, II30178N50, LA 8223 systems used in heavy commercial vehicles. This part provides precise pressure regulation and maintains system integrity through specialized port configurations and a robust 24 V heater mechanism.

Workshop technicians can rely on this unit for seamless installation into existing brake systems. The specific port sizes—including 1/2' NPTF and 1/4" NPTF specifications—allow for direct compatibility with standard heavy-duty pneumatic lines. Regular maintenance of the air dryer components is critical to prevent moisture buildup and ensure long-term braking efficiency in fleet management.

Maintaining consistent air pressure is vital for preventing system failures in truck and bus applications. This valve is engineered to withstand high-pressure fluctuations while providing reliable filtration for the entire pneumatic circuit.
