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 automatically adjusting braking force based on the vehicle load. By sensing the weight through the suspension or axle, the valve ensures that the braking pressure is always proportional to the mass being transported, preventing wheel lock-up or excessive stopping distances.

Vehicle and system compatibility

The component is designed for high-performance integration within heavy-duty brake systems and is compatible with DAF and Iveco trucks. It functions seamlessly with WABCO systems to provide reliable, graduated pressure regulation during every braking event.

Technical specifications and installation

Technical specifications include precise port sizing, featuring M22x1.5 and M16x1.5 connections, along with M12x1.5 ports. The unit maintains specific pressure thresholds, such as 7.6 BAR at full pressure on Port 2 and 2.5 BAR on Ports 41 and 42, ensuring stability under varying loads. Workshop technicians should inspect these valves during routine brake system maintenance to ensure optimal seal integrity and mechanical movement.

Maintenance importance

Maintaining proper calibration of the load-sensing mechanism is essential for fleet safety and vehicle stability.
