Description

What does an ALB Load Sensing Valve do?

This ALB Load Sensing Valve plays a critical role in the pneumatic brake system of heavy commercial vehicles by automatically adjusting braking force based on the vehicle load. By regulating pressure through specific ports, it ensures stable braking performance regardless of the weight carried by the truck. It is manufactured using high-strength components to withstand demanding operating conditions.

Vehicle and system compatibility

This component is compatible with MAN vehicles and meets the requirements of WABCO systems. It provides reliable integration within the braking architecture to maintain safety during deceleration. For optimal performance, ensure the load-sensing arm is correctly calibrated to the axle suspension.

Installation and maintenance guidance

Installation requires careful attention to the port specifications to prevent pneumatic leaks. This unit utilizes M22x1.5 Voss ports and an M16x1.5 Voss port to ensure secure connections. Technicians should verify that the empty pressure port readings, such as 0.4 BAR at port 41/42, align with the vehicle's technical requirements during maintenance.

Selection and application

Check the compatibility list to ensure this valve meets your specific requirements for heavy-duty commercial applications.
