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 adjusting brake pressure according to the actual vehicle load. By regulating air pressure through specialized ports, it ensures optimal braking performance and stability during transit.Vehicle compatibility and application
This component is designed to work seamlessly in MAN trucks and is also fitted to other heavy-duty vehicles in the segment. It operates in coordination with the vehicle's braking architecture to maintain safety during deceleration.Technical specifications and ports
The technical configuration includes Port 1 with M22x1.5 Voss threading and Port 2 featuring dual M22x1.5 Voss connections. For precise pressure regulation, it utilizes specific settings such as 0.4 BAR at the empty pressure port and up to 8.2 BAR at the full pressure port.Maintenance and installation
Regular inspection of the valve and its connections is recommended to prevent pressure fluctuations. Consult your authorized distributor for installation guidance and to ensure correct fitment for your specific vehicle model.OE cross-reference
