303.06.0150 Compatible ALB Load Sensing Valve — Volvo

What does an ALB load sensing valve do?

This ALB load sensing valve plays a critical role in the pneumatic brake system by automatically adjusting braking force based on the vehicle's current load. By sensing the weight via the suspension link, it maintains consistent stopping performance and prevents brake lock-up during heavy transport tasks. This component is manufactured using high-strength components to ensure durability under constant pressure fluctuations.

Vehicle compatibility and engine fitment

This valve is specifically designed for a wide range of Volvo trucks, including models such as the F10, F12, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12. It is also compatible with Scania vehicles and works seamlessly within systems designed by WABCO. The unit is suitable for various engine configurations including TD70, TD71, TD100, TD101, TD102, TD103, TD120, TD121, TD122, TD123, D10A, and D12A.

Technical specifications and installation

Technicians should verify the port specifications before installation to ensure a correct fit. The valve features an Empty Pressure Port 41/42 at 0.5 BAR and a Full Pressure Port 41/42 at 6 BAR. Connection ports include M22x1.5 at Port 1 and M16x1.5 at Ports 2 and 4. Regular inspection of the sensing arm and seals is recommended to maintain optimal braking efficiency.

Maintenance and system integration

Ensuring the correct pressure regulation is vital for fleet safety and vehicle stability. When replacing these valves, always check the integrity of the pneumatic lines and the condition of the suspension linkage to prevent premature wear of the new component.
