Description
This high-strength component serves as a critical element within the pneumatic brake system, ensuring stable air pressure regulation and moisture control. Designed for heavy-duty applications, the unit provides reliable operation under constant pressure cycles to maintain system integrity.
301.03.0041 is the OE-equivalent of the KNORR-BREMSE II31477, II31477N50, and LA 8256 components used in professional heavy commercial vehicle systems. This assembly is specifically engineered to meet the rigorous demands of the KNORR-BREMSE hardware architecture, ensuring seamless integration with existing pneumatic lines.
The assembly is equipped with a 24 V heater and features specific port configurations including M22x1,5 and M12x1,5 threads to facilitate precise installation. Workshop technicians should verify port sizes and pressure ratings—specifically the 10 BAR operating threshold—during assembly to ensure optimal performance and prevent leaks in the air drying process.
Maintenance of this valve is essential for preventing moisture buildup in the braking system. Regular inspection of the port seals and the heater functionality ensures long-term reliability for heavy commercial vehicle fleets and service centers.
