Description
The ALB Load Sensing Valve is a critical component within the pneumatic brake system, designed to regulate braking force based on the vehicle's load weight. This part ensures consistent braking performance and safety by adjusting pressure through specific empty and full-load thresholds. Utilizing high-strength components, it provides reliable operation in heavy-duty commercial environments.
The 303.06.0139 is the OE equivalent of the WABCO 4757111200 used in WABCO systems. This unit features specialized port configurations including Port 1 (M16x1,5), Port 2 (M16x1,5 x2), and Port 4 (M16x1,50) to ensure a secure fit within the braking circuit.
Maintenance technicians should monitor the pressure thresholds—specifically the 0,5 BAR empty pressure and 5,2 BAR full pressure—to ensure the valve is responding correctly to load changes. Regular inspection of the M16x1,5 threaded connections is recommended to prevent pneumatic leaks and maintain system integrity during heavy-duty operations.
Vaden Original components are engineered to meet strict technical requirements for professional workshop use. For optimal performance and system compatibility, always verify the technical specifications against your existing hardware before installation.
