Description

Maintaining optimal ride height and stability in heavy commercial vehicles requires high-precision components that can withstand constant pressure changes. The levelling valve plays a critical role in the pneumatic suspension system, ensuring the vehicle maintains its correct stance during transport and loading cycles.

The 303.07.0046 is the OE equivalent of the KNORR-BREMSE SV1321 used in heavy commercial vehicle suspension systems. This component is engineered with heavy-duty grade materials to ensure durability under rigorous operating conditions. It features specific port configurations including M12x1,5 threads and a specialized 178 mm lever for reliable mechanical actuation.

For workshop technicians, this part offers a precise fit within compatible pneumatic systems. Installation should be performed by checking the integrity of the connection points and ensuring the lever movement is unobstructed. Regular maintenance of the suspension system helps prevent premature wear of the valve components.

This product is specifically designed for compatibility with KNORR-BREMSE hardware to maintain system equilibrium and performance.
