Description
What does an ALB valve do?
This ALB load sensing valve plays a critical role in the pneumatic brake system of heavy commercial vehicles. By measuring the weight through the suspension linkage, it automatically adjusts the braking force to prevent wheel lock-up and ensure stable deceleration regardless of the load carried by the vehicle.Vehicle compatibility and fitment
This component is compatible with Mercedes-Benz vehicles and is designed to work seamlessly within complex braking architectures. It maintains precise pressure regulation across various operating conditions to support reliable fleet safety.Technical specifications and installation
The technical configuration includes Port 1 with M16x1,5 threading and dual M16x1,5 Port 2 connections. Pressure regulation is maintained between an empty pressure of 1.3 BAR and a full pressure of 7 BAR at the designated ports, ensuring high-strength performance for workshop technicians during installation.Maintenance and troubleshooting
Regular inspection of the sensing arm and sealing components is recommended to prevent pressure drops. For optimal system integration, ensure all port connections are secured to the specified torque to maintain consistent load-sensitive braking response.OE cross-reference
