Description
The pneumatic system requires high-precision components to maintain constant pressure regulation and safety across multiple circuits. This high-strength component is designed to manage air distribution effectively within the braking system, ensuring that the vehicle's pneumatic stability is maintained even under heavy-duty operating conditions.
The 303.02.0042 is the OE equivalent of the KNORR-BREMSE AE4611 and II33856 components used in heavy commercial vehicle braking systems. It features a primary Port 1 of M22x1,5 and secondary ports (21, 22, 23, 24) of M16x1,5 to ensure precise fitment and pressure control. This part is engineered to meet the rigorous standards required for professional workshop maintenance.
For technicians performing maintenance, this valve operates with an opening pressure of approximately 7 BAR for most ports and a maximum operating pressure of up to 20 BAR. It is essential to verify the port sizes and pressure thresholds during installation to ensure the pneumatic circuit functions correctly without leaks or pressure drops.
Regular inspection of the valve and its connections is recommended to prevent system failures. This part provides a reliable solution for maintaining the integrity of the air brake system in professional fleets.
