    Emerson Electronic Thermostatic Expansion Valves - EX Series

      Emerson electrical control valves EX4, EX5, EX6, EX7 and
      EX8 are optimized for the control of liquid or gaseous mass
      flow in refrigeration systems. The stepper motor, which produces a precise valve opening, is energized directly from the electrical power and therefore operates independent from differential pressure ensuring stable operation at low condensing pressures.

      The valve seat and slider are made of solid ceramic for long life, low operating force, low internal leak rate and to eliminate corrosion. The positive shut off function and fast response time eliminate the need for an additional solenoid valve. The special shape of the valve slide provides for proper flow through the valve and a highly linear capacity characteristic
      between 10% and 100% of maximum capacity.

      FEATURES

    • Fully hermetic design
    • Fast full stroke time
    • Applicable to all common refrigerants (HCFC, HFC), for
      subcritical CO2 applications
    • High resolution and excellent repeatability
    • Bi-flow versions for heat pump applications
    • Positive shut-off function to eliminate the use of an
      additional solenoid valve
    • Linear flow capacity
    • Wide capacity range (10 – 100%)
    • Continuous modulation of mass flow, no stress
      (liquid hammering) in the refrigeration circuit
    • Direct coupling of motor and valve for high reliability
      (no gear mechanism)
    • Ceramic slide and port for accurate flow and minimal wear
    • Balanced force design
    • Corrosion resistant stainless steel body, and connections
