Description
The technical function of this 4-circuit protection valve is to manage air pressure distribution across multiple pneumatic circuits, ensuring that even if one circuit fails or experiences a leak, the remaining systems maintain sufficient pressure for safe operation. This component is engineered with high-strength components to withstand the rigorous demands of heavy commercial vehicle brake systems.
303.02.0010 is the OE-equivalent of the MERCEDES BENZ 002 431 93 06 and KNORR-BREMSE AE 4162 used in MAN and MERCEDES BENZ heavy commercial vehicles. This part is fully compatible with several critical OEM references including MAN 81.52151-6023, MAN 81.52151-6056, and MERCEDES BENZ 001 431 39 06, ensuring seamless integration into existing pneumatic architectures.
For workshop technicians, installation requires precise attention to the specific port sizes: Port 1 utilizes an M22x1,5 thread, while Ports 12, 21, 22, 11, 23, and 24 all utilize M16x1,5 threads. It is essential to verify the opening pressure settings (7 BAR) and closing pressure thresholds (5 BAR) during assembly to maintain system integrity. Regular maintenance of these pneumatic valves is vital for preventing air leaks and ensuring consistent braking performance in fleet operations.
