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 vehicle's load. By adjusting the brake force according to the weight on the axle, it prevents brake lock-up and ensures stable stopping distances during heavy-duty operations. Built with high-strength components, it maintains consistent performance under intense pressure cycles.

Vehicle compatibility and systems

This component is compatible with DAF and Scania vehicles, providing reliable load-sensitive braking. It is also suitable for other heavy commercial vehicle models within the same class. The valve is designed to work seamlessly with WABCO systems to ensure integrated braking safety.

Installation and technical specifications

For professional installation, technicians should verify the port specifications: Port 1 is M16x1.5, while Port 4 features an M22x1.5 connection. The valve also utilizes M12x1.5 ports (41 and 42) with specific pressure thresholds of 0.7 BAR (empty) and 4.7 BAR (full). Ensure all connections are tightened to OEM standards to prevent pneumatic leaks.

Maintenance and inspection

Regular inspection of the sensing arm and port seals is recommended to prevent uneven braking performance or air loss.

OE cross-reference
