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 utilizing a sensing mechanism, it ensures that braking force remains consistent and effective, whether the vehicle is traveling empty or fully loaded. This component is essential for maintaining stable braking performance and preventing wheel lock-up during deceleration.Vehicle compatibility and fitment
Designed for heavy commercial vehicle applications, this unit is compatible with Mercedes-Benz vehicles. The valve architecture supports integrated operation with ABS systems to enhance overall safety. It serves as a reliable replacement for existing components in the air brake system of trucks and heavy duty machinery.Technical specifications and installation
The technical configuration includes a Port 2 size of M22x1.5 (X2) and Port 1/Port 4 sizes of M16x1.5. Pressure thresholds are calibrated with an empty pressure port at 0,6 BAR and a full pressure port at 4,9 BAR to ensure accurate sensing. Technicians should verify all port connections and pressure settings during installation to ensure proper system regulation.Maintenance guidance
Consult your authorized distributor for more information regarding fitment and technical integration.OE cross-reference
