303.06.0111 Volvo ALB Load Sensing Valve Equivalent

This ALB load sensing valve plays a critical role in the pneumatic brake system of heavy commercial vehicles by regulating brake pressure based on the vehicle load. By sensing the weight distribution through the suspension, it ensures optimal braking performance and prevents wheel lock-up under varying conditions. This component is manufactured using high-strength components to withstand rigorous heavy-duty service. This specific valve is compatible with several Volvo models including the F10, F12, F7, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12 engines such as TD122 or D12A. It is also fitted to DAF trucks. The unit is designed to function seamlessly within complex braking architectures to maintain safety standards. For professional installation, technicians should verify the port connections: Port 1 utilizes an M22x1.5 thread, while Port 2 features dual M16x1.5 threads. Pressure settings are calibrated for performance, with an empty pressure port reading of 4.5 BAR and a full load reading of 6 BAR on Port 2. Always consult your authorized distributor for precise fitment guidance. Maintaining the integrity of the braking system requires regular inspection of load sensing components to prevent uneven braking force or premature wear of other pneumatic elements.
