Description
The brake system requires highly reliable components to maintain safety during operation. This 4-circuit protection valve is engineered to manage air distribution across multiple circuits with precision. It serves as a critical safety element within the pneumatic braking system of heavy commercial vehicles and specialized machinery.
The VADEN ORIGINAL 303.02.0040 is an OE equivalent of the KNORR-BREMSE AE4603, II36011, II36011004, II3601105T, and II36011N0. This component is specifically designed for compatibility with KNORR-BREMSE systems to ensure consistent pressure regulation and circuit isolation.
Equipped with specialized port configurations including Port 1 (M22x1,5) and ports 21 through 24 (M16x1,5), this valve operates at a maximum pressure of up to 20 BAR. It features precise opening and closing pressure thresholds (such as 6.3 BAR opening and 4.8 BAR closing for primary circuits) to provide optimal pneumatic stability.
Technicians should verify the port sizes and pressure thresholds during installation to ensure complete system integrity. Regular inspection of the pneumatic connections and the valve's responsiveness is recommended to maintain peak performance in heavy-duty environments.

FAQ
What are the compatible OEM reference codes for this part?
This product is compatible with the following codes: AE4603, II36011, II36011004, II3601105T, II36011N00.
What is the function of this 4-circuit protection valve?
It acts as a safety component in the pneumatic brake system by isolating different circuits to maintain pressure in case of a leak or failure in one circuit.
What are the technical port specifications?
The unit features one M22x1,5 port (Port 1) and four M16x1,5 ports (Ports 21, 22, 23, and 24) for precise pneumatic connections.
What is the maximum operating pressure of this component?
The valve is designed to operate with a maximum pressure of up to 20 BAR within the braking system.
How can I ensure this part fits my KNORR-BREMSE system?
Check that your existing system requires the specific opening/closing pressures (e.g., 6.3/4.8 BAR) and matches the M22 and M16 thread specifications.
