Description
What does an ALB load sensing valve do?
This load sensing valve plays a critical role in the pneumatic braking system by adjusting brake pressure based on the actual weight of the vehicle. By regulating the air pressure delivered to the brake chambers, it prevents brake lock-up and ensures optimal stopping distances under both empty and fully loaded conditions. It is manufactured using high-strength components to withstand heavy-duty service environments.Vehicle and system compatibility
This component is specifically designed for compatibility with Evobus vehicles. It functions seamlessly within the braking system to maintain stability during deceleration. The unit is also compatible with WABCO systems and meets the requirements for heavy commercial vehicle safety standards.Installation and technical specifications
Technicians should verify the port sizes during installation, as this unit utilizes M22x1,5 for Port 1 and M16x1,5 for Ports 2 and 4. Proper calibration of empty pressure ports (1,8 BAR to 3,8 BAR) and full pressure ports (5,4 BAR to 6 BAR) is essential for correct load sensing performance. Consult your authorized distributor.Maintenance guidance
Regular inspection of the valve body and connections is recommended to prevent pressure leaks or incorrect load sensing behavior in the pneumatic circuit.OE cross-reference
