303.06.0099 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 brake system of heavy commercial vehicles by adjusting braking force based on the vehicle load. By sensing the weight through the suspension or axle linkage, it ensures that braking performance remains consistent regardless of whether the vehicle is empty or fully loaded. This component is manufactured using high-strength components to withstand demanding road conditions.

Vehicle and engine compatibility

This part is compatible with various Volvo truck models including the F10, F12, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12, featuring engines such as TD100, TD120, TD70, and D12A. It is also fitted to DAF trucks. The valve features specific port configurations including M16x1,5 for Port 1 and Port 2, and M16x1,50 for Port 4.

Technical specifications and installation

For workshop technicians performing maintenance, it is vital to verify the pressure settings during installation. This valve operates with an empty pressure port range of 0,8 BAR to 8 BAR at ports 41/42 and 1,7 BAR to 6 BAR at port 2. Ensuring all M16 connections are correctly torqued will prevent pneumatic leaks within the braking circuit.

Maintenance and troubleshooting

Regular inspection of the load-sensing mechanism helps prevent uneven braking or pulling to one side. When replacing this component in a heavy commercial vehicle system, ensure that the pneumatic lines are free of moisture and debris to maintain optimal valve movement.
