Description

What does an ALB repair kit do?

This repair kit serves as a comprehensive overhaul solution for the automatic load sensing valve, which regulates brake force based on axle load within the pneumatic braking system. By replacing internal wearing elements, this kit ensures the valve maintains its ability to graduate air pressure effectively, preventing issues like wheel lock-up or instability under varying loads.

Compatible vehicles and systems

The components are designed to be compatible with WABCO and Knorr-Bremse systems used in heavy commercial vehicles. This includes a wide range of heavy trucks and trailers from manufacturers such as Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks. Using this kit allows for a precise restoration of the valve's original operating tolerances.

Installation and maintenance

Technicians should focus on inspecting the diaphragm, piston, and spring assembly during installation to ensure a proper seal. Replacing the O-ring and seal set is critical for maintaining pneumatic integrity. Regular inspection of these components helps prevent air leaks and ensures consistent braking performance across different load conditions.

Troubleshooting and selection

Maintaining the ALB valve through high-strength component replacement is an efficient way to manage brake system maintenance without replacing the entire valve assembly.
