Description

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 actual load of the vehicle. By utilizing a mechanical signal from the axle or suspension, it ensures that braking performance remains consistent whether the vehicle is empty or fully loaded.

Vehicle and engine compatibility

This component is designed for compatibility with Scania and DAF trucks. It functions effectively within complex braking architectures, including those integrated with ABS systems, to maintain vehicle stability during deceleration.

Installation and technical specifications

Installation requires careful attention to the specific port configurations to ensure a leak-free seal. This unit features M16x1.5 and M22x1.5 ports, with pressure-sensitive ports calibrated to 0.4 BAR for empty states and 4.7 BAR for full pressure capacity. Technicians should verify all connection points, including the M12x1.5 and M16x1.5 ports, during assembly to maintain system integrity.

Maintenance and troubleshooting

Regular inspection of the sensing arm and valve body is recommended to prevent uneven braking distribution. Consult your authorized distributor to ensure exact fitment for your specific vehicle configuration.
