Description
The braking system requires precise pressure management to ensure safety and reliability in heavy commercial vehicles. This 4-circuit protection valve is engineered to manage air distribution across multiple circuits with high precision. It features specialized port configurations including one M22x1,5 inlet and four M16x1,5 outlets to handle varied pneumatic requirements during operation.
The VADEN ORIGINAL 303.02.0084 is the OE equivalent of the KNORRBREMSE AE4405 used in specialized braking systems. This component is designed for high-strength performance and maintains consistent opening pressures of 6,5 BAR for circuits 21 and 22, and 6 BAR for circuits 23 and 24. It ensures the vehicle's pneumatic stability through rigorous testing standards.
Technical maintenance for workshop technicians involves verifying the integrity of the port connections and ensuring the closing pressures (set at approximately 4,8 BAR) function within the expected range to prevent system leaks. Regular inspection of the M16x1,5 ports is recommended during routine brake system service to ensure optimal air distribution and component longevity.
The complete compatibility list for this part includes the following OEM reference: AE4405.
