In current designs, the electronics controlling the valve are separate from the valve itself. The correct term to describe the valves is therefore electronically controlled electric valves.
Since electric valves are assigned their function in the system by the software in their controller, an electric valve can be used anywhere in the system — as an expansion valve, discharge gas bypass valve, evaporator control valve, heat reclaim valve, head pressure control valve, or crankcase pressure control valve. Several designs have evolved to meet different applications.
