Description

What does an ALB valve repair kit do?

This repair kit is designed to overhaul the ALB (automatic load sensing) valve, which is critical for regulating brake force based on axle load within pneumatic braking systems. By replacing the internal wearing elements, the valve's ability to graduate air pressure sent to brake chambers is restored to factory tolerances, ensuring stable braking performance.

Vehicle and system compatibility

The kit is compatible with Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks heavy trucks and trailers. It is specifically engineered to work with WABCO and Knorr-Bremse systems by providing the necessary internal components to maintain correct pressure graduation.

Installation and maintenance

Technicians can use this kit to address leaks or pressure irregularities by replacing the diaphragm, piston, O-ring and seal set, spring assembly, and control pin. Regular inspection of these components during brake system maintenance helps prevent wheel lock-up and ensures the braking force remains proportional to the vehicle's load.

Troubleshooting and selection

Consult your authorized distributor.

FAQ

What components are included in the repair kit?
The kit includes essential internal elements: the diaphragm, piston, O-ring and seal set, spring assembly, and the control pin.
Which systems is this repair kit compatible with?
This kit is designed for use with WABCO and Knorr-Bremse type ALB load sensing valves found in heavy commercial vehicles.
When should the ALB valve be repaired?
