Description
The Multi-circuit Protection Valve serves as a critical component within the pneumatic brake system, ensuring that pressure is distributed correctly across different circuits to maintain braking performance even if one circuit fails. This part is engineered with high-strength components to withstand rigorous heavy commercial vehicle environments.
The 303.02.0018 is the OE equivalent of the KNORR-BREMSE AE4505 and II31163N multi-circuit protection valves used in heavy commercial vehicle brake systems. It features a specialized port configuration including Port 1, 21, 22, 23, 24, 25, and 26, all utilizing M22x1,5 VOSS connections for secure integration into the pneumatic line.
For workshop technicians performing maintenance or system overhauls, this valve provides precise regulation with specific opening pressures of 9 BAR for circuits 21/22 and 7,5 BAR for circuits 23/24. It is essential to verify the port dimensions and pressure thresholds during installation to ensure compatibility with the existing vehicle brake architecture.
Regular inspection of the valve and its connections is recommended to ensure consistent pneumatic stability throughout the braking cycle.
