Description
The technical integrity of a pneumatic brake system relies on precise pressure regulation, and this 4-circuit protection valve is engineered to meet those rigorous demands. Designed for heavy commercial vehicle applications, it ensures stable air distribution across multiple circuits to maintain braking performance under varying load conditions.
This VADEN ORIGINAL 303.02.0049 is the OE equivalent of the KNORR-BREMSE AE4643 used in heavy-duty braking systems. It features specific port configurations including Port 1 (M22x1,5) and four M16x1,5 ports (21 through 24) to handle high-pressure requirements up to a maximum of 20 BAR. The product maintains an operating pressure of 13 BAR with specific opening and closing thresholds for each circuit to ensure safety and reliability.
For workshop technicians and fleet managers, this component offers a reliable solution for maintaining pneumatic circuit stability. It is essential for ensuring that the air pressure distribution between the primary system and the vehicle's various pneumatic branches remains within optimal operational parameters during transit.
Maintenance professionals should regularly check the connection points and pressure thresholds to ensure the component continues to perform according to its technical specifications.
