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 actual load of the vehicle. By utilizing a mechanical or pneumatic signal from the axle or suspension, it ensures that braking force is proportional to the weight being carried, preventing wheel lock-up and ensuring stable deceleration under various load conditions.Compatible vehicles and engines
This component is compatible with DAF, ERF, MAN, and Scania trucks. It is engineered to work seamlessly within heavy commercial vehicle brake systems where precise load-sensitive modulation is required for safety and performance.Technical specifications and ports
The technical configuration includes specific port sizes: Port 1 features an M22x1.5 Voss connection, while Port 2 utilizes two M22x1.5 Voss connections. Port 4 is equipped with an M16x1.5 Voss connection. Technicians should verify these port specifications and check the empty pressure port values of 0.3 BAR and 2.8 BAR to ensure correct installation and system calibration.Maintenance and inspection
Regular inspection of the sensing arm and valve body is recommended to prevent uneven braking performance. Maintaining the integrity of this valve is essential for the overall reliability of the vehicle's pneumatic braking system.OE cross-reference
