Description

What does an ALB load sensing valve do?

This ALB load sensing valve plays a critical role in the pneumatic braking system of heavy commercial vehicles by regulating air pressure based on the current load. By sensing the weight applied to the axle, the valve ensures that braking force is appropriately distributed, preventing wheel lock-up and maintaining stability during deceleration.

Vehicle and engine compatibility

This component is engineered for compatibility with DAF and Scania heavy-duty trucks. It is also fitted to other heavy commercial vehicle models within the same class. The assembly works seamlessly within complex braking architectures to provide consistent performance under varying load conditions.

Installation and maintenance

Installation requires careful attention to port specifications, including M22x1.5, M16x1.5, and M12x1.5 connections. Technicians should verify that the pressure thresholds—such as the 6.1 BAR full pressure at ports 41 and 42—align with the existing system requirements to ensure optimal operation.

System performance and troubleshooting

Regular inspection of the valve body and connection ports is recommended to prevent leaks or improper load sensing. Maintaining correct pressure levels across all ports ensures the integrity of the entire pneumatic braking system.

OE cross-reference
