303.06.0109 Complete, ALB Load Sensing Valve — WABCO

The heavy-duty grade materials used in this Complete, ALB Load Sensing Valve ensure precise pneumatic regulation within the braking system. This component is engineered to maintain optimal pressure distribution under varying load conditions, providing essential stability and safety for heavy commercial vehicle braking-suspension systems.

303.06.0109 is the OE-equivalent of the WABCO 475 711 038 0 Complete, ALB Load Sensing Valve used in ALEXANDER DENNIS, DAF, SCANIA, and VOLVO vehicles. This part is designed to meet exact technical specifications for seamless integration with original braking hardware.

Workshop technicians should verify the port dimensions and pressure ratings before installation. This unit features Port 1 (M22x1,5), Port 2 (M16x1,5 x2), and Port 4 (M16x1,50). Regular inspection of the pressure thresholds—specifically the Full Pressure Port 41/42 at 6,8 BAR and Port 2 at 6 BAR—is recommended to ensure optimal system performance and maintenance of braking efficiency.

This component serves as a critical part for maintaining load-sensing functionality. It ensures that the brake pressure adjusts accurately according to the weight of the vehicle or trailer-related loads during transit.
