Description
What does an ALB load sensing valve do?
This brake system component plays a critical role in maintaining safe stopping distances by regulating pneumatic pressure based on the current vehicle load. By adjusting the braking force according to weight, it prevents wheel lock-up and ensures stable deceleration during heavy-duty operations. This valve is manufactured with high-strength components to withstand rigorous commercial service conditions.Vehicle compatibility and fitment
The unit is compatible with DAF and Leyland vehicles, providing reliable performance in heavy commercial vehicle brake systems. It integrates seamlessly with existing pneumatic architectures, specifically designed to work within systems used by WABCO.Installation and maintenance guidance
For proper installation, technicians should verify all connection points, including the M22x1.5 Voss ports and the M16x1.5 Voss port 4. Maintenance should focus on ensuring the pressure regulation remains accurate between the 0.5 BAR empty pressure threshold and the 6 BAR full pressure capacity to prevent braking imbalances.Troubleshooting and service tips
Regular inspection of the sensing mechanism is recommended to ensure that load-dependent pressure adjustments remain responsive to changes in vehicle weight.OE cross-reference
