Description
The technical functionality of this 4-circuit protection valve is critical for maintaining stable pneumatic pressure across multiple braking circuits in heavy commercial vehicles. Designed with high-strength components, it regulates pressure through specific opening and closing thresholds to ensure the braking system operates within safe limits during transit.
303.02.0096 is the OE-equivalent of the KNORR-BREMSE AE 4446 4-circuit protection valve used in heavy commercial vehicle brake systems. This component is engineered to provide seamless integration and reliability within the pneumatic architecture of compatible heavy-duty vehicles.
For workshop technicians, proper installation and regular maintenance of the valve ports are essential for system longevity. The unit features a Port 1 of M22x1,5 and four M16x1,5 ports (Ports 21, 22, 23, and 24). Maintaining correct opening pressures—specifically 6,7 BAR for ports 21/22 and 7,2 BAR for ports 23/24—is vital for optimal performance and safety during heavy-duty operations.
