Description
The Multi-circuit Protection Valve is a critical component within the pneumatic brake system, designed to ensure stable air pressure distribution across multiple circuits. This high-strength component functions by regulating the flow and pressure between different braking lines, providing essential safety and stability during heavy commercial vehicle operation.
The 303.02.0023 is the OE equivalent of the KNORR-BREMSE AE4528S used in specialized braking systems. It features a technical configuration including Port 1 (M16x1,5) and multiple M22x1,5 ports (Ports 11, 21, 22, 23, 24, 25, and 26). The valve manages opening pressures between 7 and 7.5 BAR and maintains closing pressures at 4.5 BAR to ensure precise pneumatic control.
For workshop technicians performing maintenance or system overhauls, this part offers precise fitment for compatible KNORR-BREMSE hardware. It is essential to verify the port thread sizes and pressure specifications during installation to maintain optimal braking performance and system integrity within the pneumatic circuit.
