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. It functions by automatically adjusting the brake pressure based on the actual load applied to the vehicle, ensuring stable braking distances and preventing wheel lock-up under varying weight conditions.Vehicle compatibility and technical specifications
The component is compatible with MAN trucks and is engineered to meet strict requirements. It features specific port configurations including M16x1.5 ports and operates within precise pressure ranges, such as 0.45 BAR at the empty pressure port and up to 7 BAR at the full pressure port.Installation and maintenance guidance
For workshop technicians, proper installation is vital to ensure the load-sensing arm correctly measures axle weight. When replacing this component, check all connection points and ensure the M16x1.5 thread integrity to maintain system sealing. Consult your authorized distributor.System performance and troubleshooting
Regular inspection of the valve body and sensing mechanism helps prevent uneven braking performance in heavy-duty applications.OE cross-reference
