Description
This ALB Load sensing valve plays a critical role in the pneumatic braking system by regulating brake pressure based on the vehicle load. By sensing the increase in air pressure from the suspension, it ensures that the braking force is appropriately distributed to prevent wheel lock-up or excessive wear during heavy-duty operations.
The component is designed to be compatible with WABCO systems and is built using high-strength components to withstand harsh road conditions. It features specific pressure thresholds, including a 0.4 BAR empty pressure port and a full pressure port reaching up to 8 BAR, ensuring stability across all load ranges.
Installation requires careful attention to the port specifications: Port 1 utilizes M16x1.5, while Port 2 features M16x1.5(x2) and Port 4 utilizes M16x1.50. Technicians should verify all connections and ensure the pneumatic lines are free of contaminants before assembly to maintain optimal valve sensitivity.
Consult your authorized distributor for technical verification and compatibility checks.
