Description
The pneumatic brake system relies on precise pressure regulation to ensure safety and stability in heavy commercial vehicles. This 4-circuit protection valve is engineered to manage air distribution across multiple circuits, providing essential redundancy and protection for the braking system during operation.
This product is the OE equivalent of the KNORR-BREMSE AE4180 used in specialized heavy-duty systems. It features a robust design with a primary Port 1 of M22x1,5 and four secondary ports (21, 22, 23, and 24) measuring M16x1,5 each. Each circuit is calibrated with an opening pressure of 7 BAR and a closing pressure of 4,5 BAR to maintain consistent performance.
Designed for professional workshop technicians and fleet managers, this component ensures optimal air flow control within the braking network. The high-strength components are built to withstand rigorous industrial environments and constant pressure fluctuations common in heavy commercial vehicle applications.
Installation should be performed by qualified technicians to ensure the port alignments and pressure settings match the vehicle's technical requirements. Always verify the compatibility with your specific KNORR-BREMSE braking hardware before installation. Consult your authorized distributor for further technical support.
