303.06.0082 Compatible ALB Load Sensing Valve — WABCO systems

What does an ALB load sensing valve do?

This ALB load sensing valve plays a critical role in the pneumatic brake system of heavy commercial vehicles by automatically adjusting braking force based on the current load. By regulating air pressure through specialized ports, it prevents brake lock-up during light loads and ensures maximum stopping power when the vehicle is fully loaded. This component is manufactured using high-strength components to withstand demanding operational environments.

Compatible vehicles and engines

This valve is compatible with DAF and Mercedes-Benz trucks. It operates effectively within systems that require precise load-sensitive modulation, ensuring that the braking performance remains consistent regardless of the cargo weight. The unit features specific technical dimensions, including M16x1,5 ports, and is designed for integration into complex pneumatic circuits.

Installation and maintenance

For professional installation, technicians should verify the pressure settings: the empty pressure port 2 is rated at 2 BAR, while the full pressure port 2 reaches 6,5 BAR. It is essential to inspect all M16x1,5 connections to ensure a leak-free seal during the mounting process to maintain system integrity.

Troubleshooting and system care

Regular inspections of the sensing arm and port connections are recommended to prevent uneven braking force between axles. Maintaining these components helps ensure the continued safety and reliability of the vehicle's pneumatic braking system.
