ALB Load Sensing Valve

ALB Load Sensing Valve — Load-Sensitive Brake Adjustment

ALB Load Sensing Valve is a subgroup of the Brake System category and is a mechanical component that detects the amount of load carried on the vehicle's axles and automatically adjusts the pressure in the brake circuits accordingly. It prevents excessive brake pressure on an empty or lightly loaded vehicle and insufficient pressure on a loaded vehicle, providing balanced and predictable braking performance under any load condition. The valve, operating via a lever mechanism linked to suspension movement, detects the change in axle distance and gradually limits or releases the brake air pressure.

The product range offers various body and connection options suited to different vehicle and axle structures. In addition to complete valve assemblies, part-based options are also offered for easy maintenance and long service life.

• Complete ALB load sensing valve assemblies
• Control lever, connecting joint and adjustment elements
• Internal gaskets, seals and repair kits with gaskets
• Mounting bracket and fixing parts

When choosing the correct part, determining a model suited to the vehicle's axle and suspension structure is important for general compatibility with major truck and bus brands. Periodic inspection of the valve and early detection of wear at the lever and connection points directly affects the safety of the entire brake system. During maintenance, it is recommended to verify the valve's adjustment position and freedom of movement, and to determine the correct part by reviewing the product options.

Frequently Asked Questions

What is the ALB Load Sensing Valve? It is a mechanical control valve within the subgroup of the Brake System category that automatically adjusts brake air pressure according to the vehicle's load condition.

What are the failure symptoms of the ALB Load Sensing Valve? Insufficient braking on a loaded vehicle, hard braking close to wheel lock on an empty vehicle, and unbalanced brake response between axles are among the main symptoms.

When should the ALB Load Sensing Valve be replaced? When looseness appears in the control lever, an air leak occurs at the body, or a permanent deviation appears in the adjustment position, replacement of the valve or overhaul with a repair kit is required.

How is the correct ALB Load Sensing Valve selected? The model suited to the vehicle's axle count, suspension type and lever connection dimension should be determined by matching it exactly with the existing valve.

How does the ALB Load Sensing Valve relate to other parts of the Brake System? The pressure it sets works together with components such as the adjusting device and air tank, supporting overall brake balance via the ABS and the ABS double relay valve.

Why is maintenance of the ALB Load Sensing Valve important? Timely elimination of wear at the lever and connection points preserves correct brake pressure adjustment during load changes and driving safety.

Which vehicles use the ALB Load Sensing Valve? It is used in trucks, tractor units and buses with air-sprung suspension systems, and in all vehicle types requiring axle-load-sensitive braking.
