Description
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 vehicle's load. By adjusting the braking force in relation to the weight of the cargo, it ensures stable and safe deceleration under various operating conditions. This component is built with high-strength components to withstand constant pressure fluctuations.
The valve is designed to be compatible with WABCO systems, providing an essential link in the air brake circuit. It utilizes specific port dimensions including M16x1.5 for Port 1 and Port 2, alongside a dedicated Port 4. This precision ensures that the braking force is distributed correctly across the axle to prevent lock-ups or uneven braking during transport.
For workshop technicians, maintaining these valves is vital for fleet safety. Installation requires careful attention to the pressure settings, specifically managing the 0.5 BAR empty pressure and the 6 BAR full pressure thresholds. Regular inspection of the M16x1.5 connections helps prevent air leaks and ensures consistent pneumatic response across the entire braking system.
Consult your authorized distributor to confirm specific fitment for your vehicle's pneumatic configuration.
