Description
What does an ALB load sensing valve do?
This ALB load sensing valve plays a critical role in the pneumatic braking system by regulating brake pressure based on the vehicle load. By adjusting the brake force according to the weight of the heavy commercial vehicle, it ensures stable and safe stopping distances under varying load conditions. This component is manufactured with high-strength components to withstand rigorous operational demands.Technical specifications and compatibility
The valve is designed for compatibility with WABCO systems. It features specialized port configurations including M16x1.5 for Port 1 and Port 2, and M16x1.50 for Port 4. These specifications ensure precise pneumatic control within the braking circuit.Installation and maintenance guidance
For proper maintenance, technicians should verify the pressure settings during installation. This unit operates with an empty pressure port reading of 0.2 BAR at port 41/42 and reaches up to 7 BAR at full pressure port 2. Regular inspection of the ports and connections is recommended to maintain optimal braking efficiency.Operational performance
When replacing this component, ensure that all pneumatic lines are clear of contaminants to prevent valve sticking or incorrect pressure regulation.OE cross-reference
