Description
This ALB load sensing valve plays a critical role in the pneumatic braking system of heavy commercial vehicles. By measuring the load applied to the axle, it dynamically adjusts the brake pressure to ensure safe and efficient deceleration regardless of the cargo weight. This component is engineered with high-strength components to withstand constant pressure fluctuations within the brake line.
This part is compatible with Fruehauf vehicles and works seamlessly within WABCO systems. It is specifically designed to maintain stability in heavy-duty commercial vehicle braking applications where precise load-sensitive regulation is required for safety.
Technicians should verify all port connections during installation, specifically the M22x1,5 and M16x1,5 threads. Regular inspection of the sensing arm and pressure ports (such as the M12x1,5 ports) is recommended to ensure no leaks occur and that the pressure regulation remains accurate according to technical requirements. Consult your authorized distributor for fitment verification.
