303.06.0129 DAF Complete, ALB Load Sensing Valve

The pneumatic stability of a heavy commercial vehicle relies heavily on precise pressure regulation within the braking system. This ALB Load Sensing Valve is engineered to manage load-dependent air pressure changes effectively, ensuring consistent braking performance under varying weight conditions. Its robust construction is designed to withstand rigorous service environments in the transport sector.

This component serves as an OE-equivalent for DAF 1523975, MAN 81521616395, and WABCO 4757111150. It is specifically engineered for compatibility with DAF and MAN systems, providing reliable regulation for heavy-duty vehicle applications. The 303.06.0129 is the OE equivalent of the DAF 1523975 component used in professional fleet vehicles.

Technical specifications are critical for precise installation: the unit utilizes M22x1,5 Voss threads for Port 1 and the dual Port 2, while Port 4 features an M16x1,5 Voss thread. Workshop technicians should verify these port dimensions and pressure thresholds—such as the 7,2 BAR full pressure limit—to ensure seamless integration with the existing pneumatic circuit.

Maintenance of the braking system requires checking these valves during routine service intervals to prevent pressure deviations. Regular inspection of the connection ports ensures that no leaks or debris affect the load-sensing accuracy of the vehicle.
