Description
The 4-circuit protection valve plays a critical role in maintaining pneumatic stability within the brake system of heavy commercial vehicles. This component ensures that air pressure is distributed across multiple circuits, providing essential redundancy and safety during operation. Designed for high-performance environments, it utilizes high-strength components to ensure durability under constant pressure cycles.
The 303.02.0098 is the OE equivalent of the KNORR-BREMSE AE4459 used in heavy-duty pneumatic systems. This part features a specific configuration with Port 1 at M22x1,5 and Ports 21 through 24 at M16x1,5, with an opening pressure of 6,5 BAR and a closing pressure of 4,5 BAR across all circuits. It is engineered to meet the rigorous standards required for reliable air brake management.
Maintenance technicians should regularly inspect the connection points and ensure that the port threads are free from debris to maintain optimal sealing. Given its role in the braking system, verifying the pressure thresholds during routine service is essential for fleet safety and system longevity.
The Vaden Original product is designed to provide precise control within the pneumatic circuit, ensuring that the vehicle's braking performance remains consistent even under varying load conditions.
