303.02.0053-S DAF Multi-circuit Protection Valve

The multi-circuit protection valve serves as a critical component within the pneumatic brake system, ensuring the stable distribution of air pressure across different circuits. This part is engineered to maintain system integrity and provides reliable protection against pressure drops, ensuring that the heavy commercial vehicle remains safe during operation.

This component is an OE-equivalent for the DAF 1607417 S and 1612055 S, as well as various KNORR-BREMSE systems including AE 4529 S, II38749F S, II38749F004 S, II38749F0041 S, II38749FM2 S, II38749FN00 S, II38749FN50 S, and II38749FN52 S. The 303.02.0053-S is the OE equivalent of the DAF 1612055 S multi-circuit protection valve used in DAF heavy commercial vehicles.

Workshop technicians should ensure that all pneumatic lines are clear of debris before installation to maintain optimal performance. Regular inspections of the valve connections and air supply lines are recommended to prevent leaks and ensure the long-term durability of the braking system.

When replacing this part, verify that the mounting orientation matches the original component to ensure seamless integration with the existing brake circuit architecture.
