Description
What does an ALB load sensing valve do?
This ALB load sensing valve plays a critical role in the pneumatic braking system by adjusting brake pressure according to the weight of the vehicle. By sensing the axle load, it ensures that braking force is distributed correctly, preventing wheel lock-up and maintaining stability during deceleration in heavy-duty applications.Vehicle and system compatibility
This component is designed for use in DAF trucks and is also fitted to other heavy commercial vehicle brands. It functions seamlessly within systems requiring precise pressure regulation to maintain safety standards across different load conditions.Technical specifications and maintenance
The valve features specific technical specifications including M16x1.5 threading on Port 1 and Port 2, with Port 4 also utilizing an M16x1.50 configuration. Maintenance technicians should verify the empty pressure port settings at 0.5 BAR and 1.4 BAR, while ensuring full pressure reaches the required 5.9 to 6 BAR range during testing.Troubleshooting and selection
Consult your authorized distributor for installation guidance and to ensure correct alignment with the load-sensing arm mechanism.OE cross-reference
