Description
What does an ALB load sensing valve do?
This ALB load sensing valve plays a critical role in the pneumatic braking system of heavy commercial vehicles by adjusting brake pressure according to the current load. By utilizing a sensing mechanism, it ensures that braking force is distributed appropriately, maintaining stability and safety during deceleration.Vehicle compatibility and fitment
The component is compatible with MAN vehicles and functions seamlessly within braking systems requiring precise pressure regulation. It is engineered to meet the rigorous demands of heavy-duty service environments, ensuring reliable operation of the vehicle's pneumatic circuits.Installation and maintenance guidance
For installation, technicians should verify the port specifications, which include M22x1.5 Voss and M16x1.5 Voss connections. Proper maintenance involves checking the empty pressure port at 0.4 BAR and ensuring full pressure port reaches 8 BAR to maintain system integrity. Consult your authorized distributor for fitment guidance.OE cross-reference
