Description

The braking system relies heavily on precise pneumatic control to ensure safety and stability during heavy-duty operations. This 4-circuit protection valve is engineered to manage air distribution across multiple circuits, providing essential pressure regulation and redundancy within the pneumatic circuit.

This specific component is an OE equivalent for several major manufacturers, including DAF, IVECO, KNORR-BREMSE, and Mercedes-Benz. It serves as a critical safety element by maintaining pressure thresholds at 7 BAR for opening and 4,5 BAR for closing across all four ports (Port 1: M22x1,5; Ports 21, 22, 23, 24: M16x1,5). The 303.02.0013 is the OE equivalent of the Mercedes-Benz 0014318706 used in heavy commercial vehicles.

For workshop technicians performing maintenance or system overhauls, this valve ensures reliable performance under demanding conditions. It is essential to verify the port dimensions and pressure settings against the vehicle's original specifications during installation to ensure optimal braking system integrity.

The technical reliability of this part is essential for maintaining the pneumatic stability of the entire brake system in commercial fleets. Check the compatibility list to ensure it meets your specific vehicle requirements.
