The Air Suspension Solenoid Valve 4728800300 is a WABCO compact control block for the electronically controlled air suspension of heavy trucks and trailers. The modular valve block combines several functions in one compact body, saving installation space and reducing the number of air connections, so there are fewer joints that could leak over time. The valve manages the air inflow and outflow of the air springs to set the chassis height accurately.
The unit is built for tough working conditions. It offers high pressure resistance and IP6K11K waterproof and dustproof sealing, so it keeps working in rain, mud and dust. A built-in silencer reduces exhaust noise, and system self-diagnosis makes maintenance quick and predictable.

This air suspension solenoid valve is used on heavy trucks and semi-trailers fitted with electronically controlled air suspension. It allows the chassis height to be raised or lowered for loading, unloading, coupling and driving on rough ground.
The valve is well suited to tankers, tippers and container trailers, where stable height control protects the load and reduces stress on the chassis and suspension components.
Packaging & Quality AssuranceEvery air suspension solenoid valve is packed in a neutral export carton with protective foam, and each unit is bagged to keep the ports and connectors clean. OEM cartons and private labels are available, and the carton is labelled with the part number for easy identification.
All valves are produced to original equipment specification and checked before shipping. We provide a twelve-month warranty and full technical support, and we invite enquiries for samples, volume pricing and delivery schedules.
