Description
A high-strength 4-circuit protection valve is a critical component within the pneumatic brake system of heavy commercial vehicles. It ensures the stable distribution of compressed air across multiple circuits, providing essential safety and redundancy during operation. This component is engineered to withstand demanding service conditions in the heavy-duty sector.
The 303.02.0079 is the OE equivalent of the KNORR-BREMSE AE4185 used in professional braking systems. It features specific port configurations including one M22x1,5 port and four M16x1,5 ports (Ports 21, 22, 23, and 24). Each circuit operates with an opening pressure of 7 BAR and a closing pressure of 4,5 BAR to maintain optimal pneumatic stability.
For workshop technicians and fleet managers, this part offers precise control over air distribution. Maintenance should involve regular checks of the port connections and ensuring that the pressure thresholds meet the specified technical requirements to prevent system failure or pneumatic leakage.
This product is designed for high-reliability applications within the brake system architecture. It serves as a robust replacement for original components in specialized braking networks.
