Description
The pneumatic brake system relies on precise pressure management to ensure safety and stability during heavy-duty operations. This 4-circuit protection valve is engineered to manage air distribution across multiple circuits, providing critical redundancy and control within the braking architecture.
The VADEN ORIGINAL 303.02.0075 is the OE equivalent of the KNORR-BREMSE AE4171 4-circuit protection valve used in specialized braking systems. This component is specifically engineered for compatibility with KNORR-BREMSE hardware, ensuring precise opening pressures of 7,9 BAR and closing pressures of 6,4 BAR across all four ports (Port 21, 22, 23, and 24).
Designed with high-strength components, this valve features standardized port sizes including one M22x1,5 connection and four M16x1,5 connections. The robust construction is tailored for workshop technicians and fleet managers who require reliable pneumatic regulation in demanding environments.
Maintenance professionals should regularly inspect the port seals and pressure thresholds to ensure optimal system performance. This part serves as a critical element in maintaining consistent air pressure across the pneumatic circuit to prevent system failures during transit.
