303.02.0060 KNORR-BREMSE Compatible Multi-circuit Protection Valve

The multi-circuit protection valve plays a critical role in the pneumatic braking system of heavy commercial vehicles, ensuring that air pressure is distributed correctly across different circuits to maintain safety during operation. This component is engineered with high-strength components to withstand constant pressure fluctuations and ensure long-term durability in demanding environments.

303.02.0060 is the OE equivalent of the KNORR-BREMSE AE 4516 S multi-circuit protection valve used in heavy commercial vehicle brake systems. The unit features specific port configurations including Port 21 (M16x1,5), Port 22 (M16x1,5), Port 23 (M16x1,5), Port 24 (M16x1,5), and Port 26 (M22x1,5). It is designed to operate with specific opening pressures of 7,5 BAR for ports 21, 22, and 23, and 8 BAR for port 24, while maintaining a closing pressure of 6,5 BAR for the respective circuits.

For workshop technicians performing maintenance or repairs, this valve provides a precise fit within the brake system architecture. Regular inspection of the pneumatic connections and port integrity is recommended during service intervals to ensure optimal performance of the multi-circuit protection system. The component's robust construction ensures it meets the rigorous requirements of professional heavy-duty vehicle service.
