EX3 Electronic Expansion Valves

Emerson

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.

Features

  • Positive shut-off, no need for a battery
  • IP67 Moisture Protection - Operates in humid, icy, and wet environments
  • Superior control resolution for high efficiency (stepper motor driven)
  • Very long life, High reliability
  • Take-apart construction for easy field serviceability– Cleanable/removable strainer– Field exchangeable pin and orifice
  • 1 valve assembly with 8 field serviceable pin/orifice combinations for flexible capacity
