The WABCO ECAS Solenoid Valve (part number 4728800640) is a modular integrated valve block that sits at the centre of an electronically controlled air suspension system. Its compact one-piece design saves valuable installation space and sharply reduces the number of air pipeline connections, which simplifies assembly and removes potential leak points. By controlling the air inflow and outflow of each air spring, the valve automatically raises or lowers the vehicle to the required ride height.
Precision and durability are built in. The valve reacts quickly to electronic commands, holds steady under high pressure and is protected to IP6K9K, so it performs reliably in rain, dust and road spray. A built-in silencer quietens exhaust air, and full system self-diagnosis makes troubleshooting fast and maintenance straightforward.

This ECAS solenoid valve is used on heavy-duty trucks and semi-trailers that run electronically controlled air suspension, including long-haul tractors, tipper trucks, tankers and specialized trailers. It lets the driver or the control unit set the chassis height for loading, unloading, coupling and different road conditions.
Because the valve controls each air spring independently, it also helps to level the vehicle under uneven loads and to protect the chassis and cargo from excessive movement, which is valuable for tankers, bulk haulers and high-value freight.
Packaging & Quality AssuranceEvery ECAS solenoid valve is packed in a neutral export carton with protective foam, and each part is individually bagged to keep the ports and connectors clean. OEM cartons and private labels are available, and the part number is printed on the label for quick identification.
All valves are produced to original equipment specification, checked before packing and covered by a twelve-month warranty. Please contact us for samples, volume pricing and confirmed delivery times.
