Description

Maintaining optimal braking performance in heavy commercial vehicles requires precise pressure regulation based on axle load. This repair kit is engineered to overhaul the internal components of the ALB (Automatic Load Sensing) valve, ensuring the pneumatic braking system functions according to factory tolerances without the need for a full valve replacement.

The 303.06.0170.03 is the OE equivalent of the WABCO and Knorr-Bremse type ALB load sensing valves used in heavy trucks and trailers. This kit includes essential wearing elements such as the diaphragm, piston, O-ring and seal set, spring assembly, and control pin to restore graduated brake pressure regulation.

Technicians should inspect the valve's ability to sense axle load signals—whether mechanical or pneumatic—during routine maintenance. Replacing internal seals and springs can prevent wheel lock-up and trailer sway caused by improper brake force apportionment.

When performing an overhaul, ensure all ports are clear and the new sealing elements are seated correctly within the valve body to maintain high-strength performance under heavy-duty operating conditions.

FAQ

What does an ALB Load Sensing Valve repair kit include?
The kit covers the wearing elements inside the valve: the diaphragm, piston, O-ring and seal set, spring assembly, and control pin.
When should I replace the ALB valve repair kit?
Replacement is recommended if the braking force becomes inconsistent with the axle load or if there are signs of pneumatic leaks in the braking system.
Is this kit compatible with WABCO or Knorr-Bremse valves?
Yes, this kit is designed for use in WABCO and Knorr-Bremse type ALB load sensing valves found in heavy commercial vehicles.
What is the function of an ALB valve?
An ALB valve reads axle load signals to automatically regulate air pressure sent to brake chambers, ensuring braking force stays proportional to the load.
Can this kit be used on trailers?
Yes, these components are suitable for maintaining the pneumatic braking systems of both heavy trucks and trailers.
