EX3 Electronic TX Valves

The Emerson EX3 is an electronically controlled expansion device that provides precise control of refrigerant flow and system superheat. The EX3 employs a high resolution, linear stepper motor in conjunction with a built-in solenoid to provide positive closure in the event of power interruption. This automatic ”shut-off” capability, combined with a take-a-part construction and water resistant design, make the EX3 a robust solution for many applications including supermarket cases and walk-ins.
