303.06.0106 WABCO Complete, ALB Load Sensing Valve

This heavy-duty ALB Load Sensing Valve plays a critical role in the pneumatic brake system of heavy commercial vehicles, ensuring precise pressure regulation based on load changes. Built with high-strength components, it provides the stability required for long-haul transport and heavy-duty operations. The unit features specific port configurations including M22x1,5 for Port 1 and M16x1,5 for Ports 2 and 4 to ensure a secure and reliable connection.

303.06.0106 is the OE-equivalent of the VOLVO 1197970 and WABCO 475 711 018 0 used in heavy commercial vehicle braking systems. This component is engineered to meet the strict requirements of the braking architecture found in premium truck and bus chassis. It ensures that the load-sensing functionality remains accurate under varying weight distributions.

For workshop technicians, this complete assembly offers a direct replacement solution that simplifies maintenance and reduces downtime. The installation requires precision when connecting to the existing pneumatic lines to maintain optimal system pressure. Regular inspections of the port connections and pressure thresholds are recommended to ensure long-term reliability within the braking system.

Technicians should verify the pressure settings during assembly: Empty Pressure Port 41/42 operates at 2,75 BAR, while the Full Pressure Port 41/42 reaches 6,8 BAR. Maintaining these specific metrics is essential for the correct functioning of the vehicle's load-sensing capabilities.
