Description
The braking system relies on precise pressure management to ensure safety and stability during heavy-duty operations. This high-strength component is designed to manage pneumatic air distribution across multiple circuits effectively.
The 303.02.0071 is the OE equivalent of the KNORR-BREMSE AE4452 4-circuit protection valve used in heavy commercial vehicle systems. This component features specific port configurations including Port 1 (M22x1,5) and multiple M16x1,5 ports (Ports 11, 12, 21, 22, 23, and 24) to ensure reliable air circuit isolation. It operates with a maximum pressure of up to 10 BAR and features precise opening and closing thresholds for each circuit.
Maintenance technicians should verify the port thread sizes and pressure thresholds during installation to maintain system integrity. This part is engineered to meet strict industrial standards for durability and performance in demanding environments.
For optimal performance, ensure the pneumatic lines are free from obstructions and that the pressure settings align with the specified technical documentation for the vehicle system.
