Description
What does an ALB load sensing valve do?
This load sensing valve plays a critical role in the pneumatic braking system by automatically adjusting brake pressure based on the current vehicle load. By monitoring weight changes through the axle or suspension, it ensures that braking performance remains consistent and safe, preventing wheel lock-up in light loads or insufficient braking in heavy loads.Compatible vehicles and engines
Designed for heavy commercial vehicle applications, this component is compatible with DAF and Leyland trucks. It functions effectively within integrated ABS systems to maintain optimal braking stability across different driving conditions.Installation and maintenance
The unit features specific technical specifications including M22x1.5 Voss ports and an M16x1.5 Voss port. For professional installation, technicians should verify the empty pressure port settings of 0.8 BAR to 1.7 BAR and full pressure ratings of 6 BAR to 8 BAR to ensure accurate load sensing calibration.Troubleshooting and selection
Regular inspection of the valve body and sealing components is recommended during routine brake system maintenance to prevent pressure drops or improper load sensing response.OE cross-reference
