Emerson DX3-020 Stepper Motor Driven Electronic Expansion Valve 5/8 ODFPCN 098305 
 
The Emerson DX3 is an electronically operated expansion device that provides precise control of refrigerant flow and system superheat. The DX3 employs a high resolution linear stepper motor actuator with a “Dry” stator which provides excellent field serviceability, flexibility and high reliability. The patented bi-flow design contributes DX3 achieving completely equal high MOPD performance in both flow directions. In addition, the DX3 also employs the take-apart body and IP65/IP67 protected stators. The unique features and capacity range of the DX3 make it be an appropriate solution for electric bus AC and heat pump, commercial heat pump, modular air-conditioning, process chiller, etc.
