Description
What does an ALB Load Sensing Valve do?
This load sensing valve plays a critical role in the pneumatic brake system by regulating pressure based on the vehicle load. It ensures that braking force is applied proportionally to the weight of the vehicle, maintaining stability and preventing wheel lock-up during deceleration. The component is manufactured using high-strength components to withstand heavy-duty operating conditions.System compatibility
This part is designed to be compatible with WABCO systems. Its precise engineering ensures seamless integration within complex pneumatic brake circuits used in heavy commercial vehicles.Installation and maintenance
The valve features a specific port arrangement including M22x1,5, M16x1,5, and M12x1,5 connections. Technicians should verify the specific port requirements—such as the 4 BAR pressure settings for ports 41 and 42—to ensure correct installation and system calibration.Troubleshooting guidance
Regular inspection of the valve ports and seals is recommended to prevent pressure leaks. If braking response feels inconsistent under varying loads, consult your authorized distributor to check for component wear or improper calibration.OE cross-reference
