Description

The pneumatic brake system relies on precision components to ensure safety and operational efficiency. This 4-circuit protection valve is engineered to manage air distribution across multiple circuits, maintaining constant pressure even during system fluctuations.

The VADEN ORIGINAL 303.02.0086 is the OE equivalent of the KNORR-BREMSE AE4463 4-circuit protection valve used in heavy commercial vehicle brake systems. This part features specific port configurations including Port 1 (M22x1,5) and several M16x1,5 ports to ensure seamless integration with existing hardware. It is designed for high-strength performance in demanding environments.

Technicians should verify the specific opening and closing pressures during installation to ensure optimal system performance. The technical specifications for this unit include an opening pressure of 6,8 BAR for ports 21, 22, and 24, and a slightly higher pressure of 7 BAR for port 23. Such precision ensures that the brake system reacts correctly to pressure changes within the vehicle's pneumatic circuit.

Regular inspection of the valve and its connection points is recommended to maintain the integrity of the air brake system. Check all port seals and ensure that the M16x1,5 and M22x1,5 connections are secure to prevent air leaks in the heavy commercial vehicle system.
