Height control valves are an essential piece for a working air suspension, providing a stable platform for your load and a comfortable ride for the driver. The air in the supply tank that feeds the air suspension system is controlled by the height control valve; therefore a faulty height control valve can result in poor ride quality, shifting loads and possible cargo damage. If the air in the supply tank can’t get to the air springs quick enough the many benefits of using air suspension are lost and it would be like riding on a solid block of rubber.
