Precision-built, heavy-duty, self-contained, iron-bodied automatic flow regulator can be used as a liquid-control device for ammonia overfeed systems. Once set, Model AFR-3 maintains a constant flow rate of liquid to the evaporator. It also serves as a check valve to prevent backflow into the liquid line from the evaporator during pressure reversals such as occur during hot gas defrost.
