It maintains consistent air pressure to trailer tires by regulating compressed air flow from the vehicle's air supply. Over time, the valve can wear or clog, causing improper tire inflation; replacing it restores accurate pressure control. It is a genuine Meritor component, typically mounted inside the control box on the axle or hub.
