Description

This high-strength component is essential for maintaining optimal pneumatic pressure within the brake system. Designed for heavy commercial vehicle applications, this Complete, Air Dryer Valve ensures the removal of moisture and contaminants from the air supply, protecting downstream components from damage and ensuring consistent braking performance.

The 301.03.0019 is the OE equivalent of the DAF ACU8494, ACU8494A, ACU8494R and the KNORR-BREMSE II30178, II30178AT, II30178N50, LA8223 models used in heavy-duty vehicles. This part is engineered to meet rigorous standards for durability and precision in high-pressure environments.

Technical specifications include a 24 V heater and specific port dimensions (Port 1: 1/2' NPTF, Port 21: 1/2' NPTF, Port 22: 1/4" NPTF, Port 4/23: 1/4" NPTF) to ensure a secure fit during installation. Workshop technicians should verify compatibility with existing pneumatic lines and pressure requirements of 8,4 BAR before replacement.

Regular inspection of the air dryer assembly is recommended to prevent system contamination and ensure long-term reliability in the brake system.
