303.06.0110 Volvo ALB Load Sensing Valve Equivalent

What does an ALB load sensing valve do?

This ALB load sensing valve plays a critical role in the pneumatic braking system by automatically adjusting brake pressure based on the vehicle load. By sensing the weight through the suspension linkage, it ensures optimal braking performance and prevents wheel lock-up under varying cargo weights. This component is manufactured using high-strength components to withstand heavy-duty service conditions.

Vehicle and engine compatibility

This part is specifically designed for Volvo truck models including the F7, F10, F12, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12. It is also compatible with Alexander Dennis vehicles. The valve ensures that braking force is distributed appropriately across the axle to maintain vehicle stability during deceleration.

Installation and maintenance

Installation should be performed by a workshop technician to ensure correct port alignment and sealing. Technical specifications include an empty pressure port of 1.75 BAR and a full pressure port of 5.2 BAR at port 41/42, with M22x1.5 and M16x1.5 thread sizes for precise fitting. Regular inspection of the sensing arm and seals is recommended to prevent pressure fluctuations.

Selection guidance

Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
