Description

The braking system relies on precision components to ensure safety and stability in heavy commercial vehicles. This 4-circuit protection valve is engineered to manage air distribution across multiple circuits, ensuring that even if one circuit fails, the others remain functional to maintain braking capability.

The VADEN ORIGINAL 303.02.0005 is the OE equivalent of the KNORR-BREMSE AE4612, II38801F, and MAN N1.011066148 used in professional transport systems. This component is specifically designed to meet the rigorous demands of heavy-duty operation within the brake system architecture.

Technicians can rely on the precise pressure thresholds of this unit, featuring an operating pressure of 12 BAR and specific opening pressures (7 BAR for ports 21, 22, 23 and 7.2 BAR for port 24). The M22x1,5 and M16x1,5 port configurations ensure a standard fitment for authorized maintenance and system upgrades.

Regular inspection of the pneumatic connections and pressure levels is recommended during routine workshop service to ensure optimal performance of the braking circuits.
