303.06.0079 Compatible ALB Load Sensing Valve

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 automatically adjusting braking force based on the current vehicle load. By utilizing a mechanical sensing mechanism, it ensures that braking pressure is distributed correctly, preventing wheel lock-up during light loads and providing sufficient stopping power when the vehicle is fully laden.

Vehicle and engine compatibility

This component is compatible with DAF and Mercedes-Benz trucks. It is specifically designed to function within complex pneumatic circuits, maintaining high-strength performance under heavy-duty service conditions. The valve is engineered to meet the rigorous demands of professional fleet operations.

Technical specifications and installation

For technical installation, note the specific port configurations: Port 1 uses M16x1.5, while Port 2 features dual M16x1.5 connections. The system operates with an empty pressure port setting of 0.8 BAR and a full pressure port setting of 6.5 BAR to ensure accurate load sensing. Technicians should verify all sealings and port clearances during assembly to maintain system integrity.

Maintenance guidance

Regular inspection of the load-sensing arm and valve body is recommended to prevent uneven braking performance across the axle.
