Height Control Levelling Valve 4640061000 WABCO Air Spring for Trailer Air Suspension System

The WABCO WABCO Levelling Valve (part number 4640061000) is a replacement component for the air brake and air suspension systems of heavy-duty trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include Max Working Pressure 13 bar, temperature range -40°C ~ +80°C, Port Thread M12*1.5 / M16*1.5, actuation angle 90°, aluminium body, weight 0.51kg.

A hard-wearing lever mechanism and corrosion-resistant body keep the valve accurate through many thousands of load cycles, and the compact design fits the same mounting points as the original part. Correct ride height protects the chassis, reduces tyre and air spring wear, and keeps the vehicle level for safe handling whether it is empty or fully loaded.

Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.

• Max Working pressure:13 Bar: Temperature range -40°C ~ +80°C.
• Port Thread: M12*1.5 / M16*1.5: Actuation angle 90°, aluminium body, weight 0.51kg.
• 2-circuit Design: Two-stage regulation, automatically controls inflation and deflation of air springs to maintain chassis height.
• OE Original Quality: Stable under strong vibration, precise height adjustment, long service life.
• Suitable for Heavy Trucks and Coaches With: Mechanical air suspension.

The valve is fitted to the air-suspension systems of heavy trucks, buses and semi-trailers, including long-haul tractors, tippers, tankers and coaches. It is ideal for vehicles that carry varying loads or run on rough ground, because it holds a constant ride height that protects the chassis, cargo and tyres.

Every unit is packed in a neutral export carton with foam protection so that ports, connectors and levers arrive free from damage. OEM cartons and private labels are available on request, and each carton is labelled with the part number for simple warehouse handling.
