Description

The technical function of this ALB Load Sensing Valve is to regulate brake system pressure based on the vehicle's load, ensuring optimal braking performance and stability. Manufactured with high-strength components, this part provides essential regulation within the pneumatic braking circuit to maintain safety during varying load conditions in heavy commercial vehicles.

This product is the OE-equivalent of the WABCO 475 711 074 0 ALB Load Sensing Valve used in DAF, SCANIA, and VOLVO heavy commercial vehicle systems. It also serves as a direct replacement for SCANIA 1935091 and VOLVO 1628954 models. The precise port configuration—including M22x1,5 for Port 1 and M16x1,5 for Ports 2 and 4—ensures seamless integration with existing pneumatic lines.

For workshop technicians performing maintenance or assembly, this valve requires careful inspection of the port connections to ensure airtight seals. Regular checks of the pressure thresholds—specifically the 6 BAR full pressure at Port 2 and the 1,2 BAR empty pressure at Port el—are recommended to maintain optimal braking responsiveness. Proper installation of this component is vital for the correct functioning of the load-sensing mechanism in heavy-duty truck and bus chassis.
