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 regulating brake pressure based on the actual load of the vehicle. By sensing the weight through the suspension linkage, it prevents brake lock-up during light loads and ensures maximum stopping power when the vehicle is fully loaded. This component is manufactured with high-strength components to withstand rigorous heavy-duty operating conditions.Vehicle and system compatibility
This specific valve is compatible with MAN and PACCAR trucks, as well as WABCO systems. It utilizes M16x1.5 threading for Port 1 and Port 4, while Port 2 features dual M16x1.5 connections to facilitate proper pneumatic routing within the braking circuit.Technical specifications and installation
For professional technicians, maintaining correct pressure thresholds is vital for safety. This unit manages an empty pressure port range from 0.4 BAR to 1.9 BAR and a full pressure range from 4.7 BAR to 7 BAR. Regular inspection of the sensing arm and seal integrity is recommended to prevent uneven braking performance.Maintenance and performance monitoring
When replacing this component, ensure all pneumatic lines are clear of debris and that the mounting surface is prepared according to OEM standards to maintain system integrity.OE cross-reference
