Description
What does an ALB Load Sensing Valve do?
This ALB Load Sensing Valve plays a critical role in the pneumatic braking system by automatically adjusting the braking force based on the vehicle load. By utilizing a load-sensing mechanism, it ensures that the braking performance remains consistent whether the vehicle is carrying a full load or traveling empty, preventing brake lock-up or increased stopping distances.Compatible vehicles and engine systems
This component is compatible with Iveco trucks and is engineered to meet rigorous heavy commercial vehicle standards. It works seamlessly within the pneumatic braking architecture, often integrated with ABS systems to maintain stability during deceleration. The valve features specific port configurations including M22x1.5, M16x1.5, and M12x1.5 to ensure precise hydraulic-pneumatic integration.Installation and maintenance guidance
For workshop technicians, maintaining correct pressure settings is vital for safety. This valve features specific pressure thresholds, such as 2.6 BAR for empty states and up to 7.6 BAR for full load states on Port 2, with calibration points at 1.65 BAR and 3.25 BAR on auxiliary ports. Regular inspection of the sealing components and port integrity is recommended during routine brake system service.Pressure specification overview
When replacing this unit, ensure all connections are tightened to specification to prevent air leaks in the braking circuit. This part serves as a reliable replacement for components used in heavy-duty commercial applications.OE cross-reference
