TAG AXLE CONTROL VALVE. The tag axle control valve is a component of the pneumatic suspension system used in trucks, buses and trailers equipped with a liftable or load‑sharing auxiliary axle known as a tag axle. The primary function of this component is to regulate the supply of compressed air to the pneumatic suspension elements in order to raise or lower the additional axle depending on the vehicle load. A tag axle is used to distribute the vehicle weight more evenly and increase load capacity. When the vehicle is unloaded or lightly loaded, the axle can be lifted to reduce tire wear, decrease rolling resistance and improve vehicle maneuverability. The control valve regulates the air pressure in the suspension air springs, ensuring proper operation of the lifting and lowering mechanism. The valve may operate automatically by responding to pressure changes in the pneumatic system or may be controlled manually through the vehicle suspension control system. Tag axle control valves are manufactured from durable metal and composite materials resistant to high pressure, temperature fluctuations, moisture and contamination typical for commercial vehicle operation. Reliable operation of the valve ensures proper pneumatic suspension performance, correct load distribution between axles and improved safety and efficiency of vehicle operation. The catalog includes tag axle control valves of various designs and configurations intended for installation on trucks, buses, trailers and semi‑trailers.

Additional information

Tag axle control valve by KNORR-BREMSE, OEM AE1141, is a component that transmits, distributes, or processes signals and commands within the relevant vehicle electronic system. The source data describes this item as “Клапан керування віссю лінивця”. Correct operation of this part supports the related assembly and the vehicle functions designed around it. Possible fault signs include unstable operation of the related system, diagnostic trouble codes, no response to commands, or intermittent failures. A single symptom does not always prove that this exact component has failed, so power supply, wiring, mountings, or adjacent parts should be checked as appropriate before replacement. Before ordering, compare connectors, labels, hardware revision, and diagnostic results; some control units may also require coding or vehicle-specific pairing. OEM AE1141 is the primary reference, but an identical product name does not guarantee compatibility across different vehicle specifications. Before purchase, compare identification and appearance with the old part and verify compatibility by VIN.
