Electric Expansion Valve Control - Feature Articles - Extra Edition - Air Conditioning, Heating & Refrigeration NEWSElectronically controlled electric valves have been accepted for years in larger applications, just as chillers have been, and have proven to add efficiency to the systems. The key to the increase in efficiency is due to their ability to control superheat to a low, stable setting. Since many chillers use almost infinitely variable screw compressors, an expansion valve that has the ability to follow these radical changes in capacity is required.
