Air Suspension Levelling Valve H450200000123 Universal Mounting Control Valve for Heavy Duty Truck

The Bellam Leveling Valve (part number H450200000123) is a replacement component for the air brake and air suspension systems. 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 original equipment ratings.

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.

• Fast Response and Precise Control: Keeps the air springs at the preset height with quick response and accurate height control.
• Vibration Resistant: Stable operation and no sticking, even under harsh heavy-duty truck conditions.
• Wide Temperature Tolerance: Works reliably across a wide temperature range without seizing or drifting.
• Low Air Leakage Seals: High-quality internal seals keep air leakage low and extend the service life of the valve.
• Universal Mounting Dimension: Bolt-on dimensions make replacement quick and straightforward.
• Wide Vehicle Compatibility: Compatible with the air suspension systems of Chinese and European heavy-duty trucks.

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. All units are produced to original equipment specification and inspected before shipment; a twelve-month quality warranty and full technical support are provided, and mixed containers can be supplied for distributors and repair workshops.
