Description

The technical function of this ALB Load Sensing Valve is to regulate braking force based on the vehicle's load, ensuring optimal pneumatic stability in the brake system. Designed with heavy-duty grade materials, this component provides essential pressure regulation for heavy commercial vehicle safety and reliability.

303.06.0020 is the OE-equivalent of the DAF 1518979 and WABCO 475 715 505 0 components used in DAF heavy commercial vehicle systems. This part ensures precise compatibility with WABCO systems and DAF braking architectures by maintaining exact pressure thresholds across its multiple specialized ports.

Workshop technicians should note the specific port configurations for assembly: Port 1 utilizes M16x1,5 while Port 2 features a complex arrangement of M22x1,5 and M16x1,5 threads. Maintenance and installation require strict adherence to these thread sizes to ensure a leak-free connection within the pneumatic braking circuit.

Detailed pressure monitoring is facilitated by the specific empty and full pressure ratings. The component maintains a consistent performance profile with an empty pressure of 0,4 BAR at ports 41 and 42, reaching a full pressure of 4,4 BAR to guarantee system integrity during high-load operations.
