303.02.0013.01 Repair Kit, 4-circuit protection valve

The 303.02.0013.01 repair kit is a specialized solution for maintaining the integrity of the braking system's pneumatic circuits. Designed for the 4-circuit protection valve, this kit ensures that the essential air pressure distribution remains stable and reliable within the heavy commercial vehicle's braking architecture.

This product serves as the OE-equivalent for the KNORR-BREMSE I80448 4-circuit protection valve used in DAF, IVECO, Mercedes-Benz, and Volvo heavy commercial vehicles. By utilizing high-strength components, it maintains the precise mechanical tolerances required for safe pneumatic operation and pressure regulation.

Workshop technicians should utilize this kit during routine maintenance or when addressing pressure drops within the pneumatic system to ensure optimal performance of the protection valve. It is essential to verify that all seals and components are seated correctly to maintain system pressure stability across all four circuits.

Regular inspection of these components helps prevent failure in critical braking stages, ensuring that the vehicle remains compliant with safety standards during long-haul operations.
