Description

This heavy-duty grade component functions as a critical pneumatic control element within the brake system. It manages pressure distribution across multiple circuits to ensure stable braking performance and safety in heavy commercial vehicles. Designed with high-strength components, it maintains precise pressure thresholds to prevent system failures during operation.

303.02.0008 is the OE-equivalent of the DAF 1519373 and 1521199, IVECO 97166254, KNORR-BREMSE AE 4613, and MAN 81.52151-6093, 81.52151-6096, or 81.52151-6097 parts used in MAN, DAF, and IVECO heavy vehicles. This part ensures seamless integration with your existing pneumatic brake hardware.

Workshop technicians can rely on the precise port specifications for assembly. The unit features one M22x1,5 main port and four M16x1,5 auxiliary ports. It is essential to verify that the operating pressure and opening/closing thresholds match the vehicle's specific technical requirements during installation and routine maintenance to ensure optimal safety.
