Description
The precision of the pneumatic braking system is vital for heavy commercial vehicle safety, and the 303.02.0057 Multi-circuit Protection Valve provides the necessary reliability for these critical operations. This component manages air distribution across multiple circuits, ensuring that pressure fluctuations in one circuit do not compromise the integrity of others. Built with high-strength components, it is engineered to withstand demanding industrial environments.
This specific part is the OE equivalent of the KNORR-BREMSE AE4562, K050701N00, and K050701N50 models used in heavy commercial vehicle brake systems. It features specialized port sizes including M16x1,5 for ports 21 through 24 and M22x1,5 for ports 25, 26, and 28. The valve is calibrated with an opening pressure of 7,5 BAR for ports 21, 22, and 23, while maintaining a closing pressure of 6 BAR for circuits 21/22 and 23/24 to ensure optimal safety.
For workshop technicians and fleet managers, maintaining the correct pressure thresholds is essential for system longevity. When replacing or installing this component, ensure all port connections—specifically the M16x1,5 and M22x1,5 interfaces—are checked for precision to prevent air leaks. Regular inspection of the pneumatic paths and valve operation is recommended to maintain peak performance within the braking system.
Consult your authorized distributor for technical verification or to check the compatibility list for your specific fleet requirements.
