Description
What does an ALB Load Sensing Valve do?
This load sensing valve plays a critical role in the pneumatic braking system by regulating brake pressure based on the vehicle load. By adjusting the braking force in proportion to the weight being carried, it ensures stable and safe deceleration under varying load conditions. This component is built with high-strength components to withstand constant pressure fluctuations.System compatibility and application
The valve is compatible with WABCO systems and provides reliable performance in heavy commercial vehicle applications. It is engineered to meet strict industrial standards for pneumatic control, ensuring that the braking force remains consistent whether the vehicle is empty or fully loaded.Installation and maintenance guidance
For proper installation, technicians should verify all port connections, including the M22x1.5, M16x1.5, and M12x1.5 interfaces. Maintaining clean connections and checking the 3.8 BAR pressure thresholds on ports 41 and 42 during routine inspections helps prevent system imbalances or uneven braking performance.OE cross-reference
