Description

The high-strength component for the air brake system ensures optimal moisture removal and air filtration within the pneumatic circuit. This complete air dryer valve is engineered to maintain consistent pressure and protect downstream components from contamination and ice formation in heavy commercial vehicles.

301.03.0026 is the OE-equivalent of the KNORR-BREMSE II31478N50 Complete, Air Dryer Valve used in KNORR-BREMSE systems. This part is fully compatible with several high-standard references including KNORR-BREMSE II30445, II30445AT, II30445N00, and LA 8231.

Workshop technicians should ensure that the port connections (M22x1,5 and M12x1,5) are properly seated to prevent air leaks. Regular inspection of the air dryer cartridge and checking the system pressure at 7,8 BAR is recommended to maintain optimal braking performance and system longevity during routine maintenance cycles.
