EX4-I21 Alco electronic control valve stepper motor powered Emerson 800615 

As today’s systems require improved energy efficiency, tighter temperature control, a wider range of operating conditions and incorporate new features like remote monitoring and diagnostics,

the application of electronically operated valves becomes mandatory. 

Only these offer the controls performance necessary to meet these needs. Electrical control valves are actuators only.

For operation in a system they need sensors, valve drivers and controllers.

Emerson electrical control valves EX4, EX5, EX6, EX7 andEX8 are optimized for the control of liquid or gaseous massflow in refrigeration systems. T

he stepper motor, whichproduces a precise valve opening, is energized directly fromthe electrical power and therefore operates independentfrom differential pressure ensuring stable operation at lowcondensing pressures.

Data Sheet

The valve seat and slider are made of solid ceramic for longlife, low operating force, low internal leak rate and toeliminate corrosion.

The positive shut off function and fastresponse time eliminate the need for an additional solenoidvalve.

The special shape of the valve slide provides for properflow through the valve and a highly linear capacity characteristicbetween 10% and 100% of maximum capacity.
