ELECTRONIC EXPANSION VALVE KIT EX3-2000

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.
