This Danfoss electronic expansion valve (EXV) is designed with an outside diameter fitting (ODF) of 1 5/8 inches, suitable for soldering into refrigeration and air conditioning systems. The valve regulates the flow of refrigerant entering the evaporator based on demand, improving system efficiency and performance. It comes equipped with an actuator, which is responsible for the precise control of the valve position, responding to signals from a system controller to adjust refrigerant flow accordingly.
