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 modulating the air pressure delivered to the brake chambers, it prevents brake lock-up during light loads and ensures maximum braking force when the vehicle is fully loaded. This regulation is essential for maintaining stable stopping distances in heavy commercial vehicles.Vehicle compatibility and application
Designed for heavy-duty applications, this component is compatible with Iveco trucks and meets high-performance standards. It is engineered to work seamlessly within complex pneumatic circuits, ensuring that the braking force remains proportional to the weight of the load carried by the vehicle.Installation and technical specifications
For technical installation, note the specific port configurations: Port 1 uses an M16x1.5 thread, while Port 2 features two M16x1.5 connections. The empty pressure port operates at 0.5 BAR and 2.4 BAR, while full pressure ports reach 5 BAR and 7.6 BAR respectively. Technicians should verify all port seals and thread alignments during assembly to ensure system integrity.Maintenance and troubleshooting
Regular inspection of the sensing mechanism is recommended to prevent uneven braking performance. If braking response feels inconsistent under varying loads, consult your authorized distributor.OE cross-reference
