Description
What does an ALB load sensing valve do?
This ALB load sensing valve plays a critical role in the pneumatic braking system of heavy commercial vehicles by adjusting brake pressure based on the actual load of the vehicle. By regulating pressure according to weight, it ensures stable braking performance and prevents wheel lock-up during deceleration. This component is manufactured with high-strength components to withstand demanding operating conditions.Compatible vehicles and engines
The valve is compatible with DAF and MAN trucks, providing reliable weight-sensitive pressure modulation. It is also designed to function within systems used by other heavy-duty vehicle manufacturers. The unit features specific port configurations including M22x1.5 Voss and M16x1.5 Voss to ensure seamless integration into existing pneumatic lines.Installation and maintenance
For workshop technicians, maintaining proper port sealing is essential during installation. This valve operates with specific pressure ranges, such as 0.45 BAR to 5 BAR on ports 41/42, ensuring accurate load sensing. Regular inspection of the pneumatic connections is recommended to prevent pressure drops in the braking circuit.Troubleshooting
Consult your authorized distributor for fitment verification.OE cross-reference
