Description
What does an ALB load sensing valve do?
This load-sensing valve plays a critical role in the pneumatic braking system of heavy commercial vehicles by automatically adjusting brake pressure according to the vehicle load. By utilizing a load-sensing arm or sensor linked to the axle, it ensures that braking performance remains consistent regardless of whether the vehicle is empty or fully loaded. This component is manufactured using high-strength components to withstand demanding operating conditions.Compatible vehicles and systems
This specific unit is compatible with Scania trucks and meets requirements for WABCO systems. It is engineered to integrate seamlessly into the braking circuit, helping maintain stability during deceleration. The valve features precise port dimensions including M16x1.5, M22x1.5, and M12x1.5, ensuring a secure fitment within the pneumatic lines.Installation and maintenance
For workshop technicians, verifying the port sizes and pressure thresholds is essential during installation. The unit includes specific pressure ports, such as Port 41 and 42, which operate at 0.2 BAR when empty and 5.6 BAR when under full pressure. Proper inspection of the mounting surfaces and connection points ensures long-term reliability in the brake system.Technical verification
Consult your authorized distributor to ensure this part meets your specific vehicle requirements.OE cross-reference
