Description
What does an ALB repair kit do?
This repair kit is designed to overhaul the automatic load sensing (ALB) valve, which regulates brake force within the pneumatic braking system of heavy commercial vehicles. By replacing the internal wearing elements, this kit helps maintain the correct balance of braking pressure relative to the actual axle load, preventing issues like wheel lock-up or instability during transit.Compatible systems and vehicles
The kit is engineered for compatibility with WABCO and Knorr-Bremse type ALB load sensing valves. It provides a precise solution for heavy trucks and trailers, ensuring that the graduated pressure regulation functions according to factory tolerances. This component is vital for maintaining safety in various heavy commercial vehicle applications.Maintenance and installation guidance
Technicians should inspect the diaphragm, piston, O-ring set, spring assembly, and control pin when servicing the braking system. Replacing these internal components is often a more efficient maintenance step than a full valve replacement when the primary valve body remains intact. Regular inspection of these sealing elements can prevent pneumatic leaks and ensure consistent braking performance.Service recommendations
Consult your authorized distributor for specific fitment details regarding your fleet's braking system requirements.Related Products

FAQ
What is included in this ALB repair kit?
The kit typically includes essential internal components such as the diaphragm, piston, O-ring and seal set, spring assembly, and the control pin required to restore valve function.
Which systems are these parts compatible with?
These repair kits are designed to be compatible with WABCO and Knorr-Bremse type ALB load sensing valves used in heavy commercial vehicle braking systems.
When should I replace the ALB valve repair kit?
Replacement is recommended when the sealing capability of the valve degrades, leading to inconsistent brake pressure or pneumatic leaks in the braking system.
How does an ALB valve regulate braking force?
The valve senses axle load via mechanical or pneumatic signals and uses that data to graduate the air pressure sent to the brake chambers, ensuring proportional braking.
