301.03.0050 KNORR-BREMSE Complete, Air Dryer Valve

The heavy-duty air dryer valve system is a vital component for maintaining pneumatic pressure and ensuring the longevity of the brake system. This complete assembly is engineered to provide reliable moisture separation and air filtration within the pneumatic circuit, protecting downstream components from contamination and pressure fluctuations.

301.03.0050 is the OE-equivalent of the KNORR-BREMSE II33424N50, II36939, II36939N49, and LA 8280 air dryer valves used in heavy commercial vehicle systems. This part is specifically designed to meet the rigorous technical standards required for seamless integration into high-pressure pneumatic networks.

Technical specifications for this unit include a 12 V heater and a working pressure of 8,5 BAR. The connection ports feature M22x1,5 configurations for Ports 1 and 21, while Port 4/23 utilizes an M16x1,5 VOSS interface. Workshop technicians should ensure all port connections are properly sealed to prevent leaks during assembly.

Maintaining the air dryer valve is essential for preventing system failures caused by moisture buildup in the brake system. Regular inspection of the port connections and ensuring compatibility with the existing pneumatic architecture will ensure long-term operational safety in heavy commercial vehicle applications.
