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-duty trucks by automatically adjusting braking force based on the vehicle's current load. By modulating pressure through specialized ports, it ensures consistent stopping power and prevents brake lock-up or excessive wear during varying weight conditions.Compatible vehicles and engines
This component is compatible with DAF, Iveco, and Renault Trucks. It is engineered to maintain high performance under heavy-duty service conditions, providing stable braking response across various load ranges.Installation and maintenance
For proper installation and maintenance, technicians should verify that all port connections, including the M16x1.5 threads on Port 1 and Port 2, are seated correctly. Checking the pressure thresholds—such as the 0.6 BAR empty pressure at Port 41/42—is essential to ensure the valve reacts accurately to axle load changes.Troubleshooting guidance
Maintaining the integrity of the pneumatic lines connected to Port 4 is vital for preventing air leaks and ensuring the load-sensing mechanism functions as intended. Consult your authorized distributor for more information.OE cross-reference
