Description
What does an ALB Load Sensing Valve do?
This ALB Load Sensing Valve plays a critical role in the pneumatic braking system by modulating brake pressure based on the vehicle load. By adjusting the braking force relative to the weight of the cargo, it prevents wheel lock-up during deceleration and ensures stable braking performance under varying load conditions.Technical specifications and compatibility
Designed to work with WABCO systems, this component is built using heavy-duty grade materials to withstand rigorous operating environments. It maintains precise pressure control, with empty pressure ports at 0.5 BAR and 2 BAR, and full pressure ports reaching up to 7.2 BAR to ensure safety and reliability.Installation and maintenance guidance
Installation requires careful attention to the M16x1.5 thread connections for Port 1, Port 2, and Port 4 to prevent air leaks. Technicians should verify all port alignments and ensure the valve is seated correctly within the pneumatic circuit to maintain optimal load-sensing sensitivity.System performance and troubleshooting
Regular inspection of the valve ports and pressure settings is recommended to prevent uneven braking force or system lag.OE cross-reference

FAQ
What is the function of an ALB Load Sensing Valve?
It regulates brake pressure by sensing the load on the vehicle, ensuring that braking force increases as the weight increases for safer stops.
Which brands is this valve compatible with?
This component is designed to be compatible with WABCO systems in heavy commercial vehicle braking circuits.
What are the thread specifications for this component?
The valve features M16x1.5 threading on Port 1, Port 2 (x2), and Port 4 to ensure secure pneumatic connections.
How can I identify a faulty load sensing valve?
Symptoms may include uneven braking or failure to adjust pressure correctly under load; technicians should check if pressure reaches the required 7.2 BAR at full load.
What are the OE reference numbers of this part?
303.06.0047 directly replaces WABCO OE number 4757110550.
