Description
What does an ALB repair kit do?
An ALB Load Sensing Valve repair kit is a replacement component set designed to overhaul the automatic load sensing valve that senses axle load and automatically regulates brake force in the pneumatic braking system of heavy commercial vehicles. This kit contains the critical internal elements including the diaphragm, piston, O-ring and seal set, spring assembly, and control pin.Vehicle and system compatibility
This repair kit is compatible with Wabco and Knorr-Bremse type ALB load sensing valves used in Mercedes-Benz, MAN, Scania, Volvo, DAF, Iveco, and Renault Trucks. It ensures that braking force remains proportional to the axle load, whether the vehicle is empty or fully loaded, helping to prevent wheel lock-up and instability.Maintenance and installation
For workshop technicians performing maintenance, using a high-quality repair kit is a highly efficient way to restore the valve's ability to graduate brake pressure according to axle load back to factory tolerances. When inspecting the braking system, check for leaks or inconsistent pressure that may indicate worn internal seals or a faulty diaphragm.Troubleshooting brake regulation
Ensuring the internal piston and spring assembly are properly seated during installation helps maintain precise pneumatic regulation. Consult your authorized distributor for further technical guidance.FAQ
What components are included in this repair kit?
The kit covers the wearing elements inside the valve, specifically the diaphragm, piston, O-ring and seal set, spring assembly, and control pin.
Which braking systems are compatible with this kit?
This kit is designed for use with Wabco and Knorr-Bremse type ALB load sensing valves found in heavy commercial vehicles.
What symptoms indicate a need for an ALB valve repair?
Technicians should look for inconsistent brake pressure or signs of air leaks which suggest that the internal seals or diaphragm have degraded.
How does an ALB valve regulate braking force?
The valve reads the compression in the axle suspension to provide a signal that graduates air pressure to the rear-axle chambers based on the current load.
