Description
What does an ALB load sensing valve do?
This ALB load sensing valve plays a critical role in the pneumatic braking system by automatically adjusting brake pressure based on the current vehicle load. By sensing the weight through the axle or suspension, it ensures that braking force is distributed effectively, preventing lock-ups and reducing uneven wear on the brake components.Vehicle and system compatibility
The component is engineered for heavy commercial vehicles, including DAF, Renault Trucks, and Scania models. It operates in harmony with existing braking systems to maintain stability during varying load conditions. This part is a high-strength solution for professional workshop technicians looking to maintain fleet safety.Installation and technical specifications
Installation requires careful attention to the specific port configurations: Port 1 features an M22x1.5 Voss thread, while Port 2 utilizes dual M22x1.5 Voss connections. Port 4 is specified as M16x1.5 Voss. Ensure all connections are tightened to specification to maintain the integrity of the pneumatic circuit.Maintenance and troubleshooting
Regular inspection of the sensing arm and valve body can help prevent premature failure in heavy-duty applications. For optimal performance, verify that the empty pressure port readings align with the system requirements of the vehicle's braking architecture.OE cross-reference
