Description
What does an ALB valve repair kit do?
This repair kit is designed to overhaul the internal components of an ALB (automatic load sensing) valve, which regulates brake force in the pneumatic braking system of heavy commercial vehicles. By replacing the internal wearing elements, the valve's ability to graduate brake pressure according to axle load is restored to factory tolerances, ensuring safety and stability during transit.Compatible vehicles and systems
The kit is compatible with Wabco and Knorr-Bremse systems and is widely used in heavy trucks and trailers from manufacturers such as Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks. It provides a precise solution for maintaining the braking equilibrium of the vehicle regardless of the load weight.Installation and maintenance
For workshop technicians, utilizing this kit is an efficient way to address leaks or pressure fluctuations caused by worn seals or diaphragms. It includes essential components like the diaphragm, piston, O-ring set, seal, spring assembly, and control pin to ensure a complete overhaul of the valve body.Troubleshooting guidance
Regular inspection of the valve components can prevent issues such as wheel lock-up or trailer sway. Check the compatibility list to ensure this kit meets the specific requirements of your braking system.Related Products

FAQ
What components are included in this repair kit?
The kit contains the essential internal elements: a diaphragm, piston, O-ring and seal set, spring assembly, and a control pin.
Which systems are these parts compatible with?
These components are designed to work with Wabco and Knorr-Bremse type ALB load sensing valves used in heavy commercial vehicles.
Why should I use a repair kit instead of a new valve?
Renewing internal parts like the diaphragm and seals is often a more economical solution than replacing the entire valve assembly when only internal wear is present.
How does an ALB valve function?
The valve senses axle load through mechanical or pneumatic signals and regulates air pressure to brake chambers so that braking force remains proportional to the load.
