Description
The high-strength components of this protection valve ensure reliable pneumatic control within the brake system. This part is essential for maintaining pressure distribution across multiple circuits, ensuring the safety and stability of heavy commercial vehicles during operation under various pressure conditions.
This product is an OE equivalent for DAF 1367504 and DAF 1521155, as well as KNORR-BREMSE AE4610, II37462, and II37462N52. It is specifically designed for compatibility with DAF and KNORR-BREMSE systems. The 303.02.0041 is the OE equivalent of the DAF 1367504 and DAF 1521155 brake system components used in heavy commercial vehicles.
Equipped with specific port configurations including M22x1,5 for Port 1 and M16x1,5 for the remaining ports, this valve manages operating pressures up to a maximum of 20 BAR. Technicians should verify the opening and closing pressure thresholds—such as the 7,3 BAR opening pressure for Port 23—to ensure correct system calibration during installation.
Regular inspection of the pneumatic connections and port integrity is recommended to maintain optimal braking performance in fleet-operated vehicles.
