Product information - Emerson Alco electrical control valve (stepper) EX6-I21

Alcos electronic expansion valves with stepper motor. Working range -50 / +80°C. Max working pressure EX4, EX5, EX6, EX7, - 45 bar, EX8 - 35 bar. Controlled by a regulator-driver, a temperature sensor and a pressure sensor. Contact Kylma for calculation of valves.
Alcos electronic expansion valves can be controlled with Alcos regulators or with Carels EVD evo universal (see section Carels electronic valves).
Control can be done in two different ways, either through a stand-alone controller EC3-X33 which can be equipped with a display for reading/programming, or with EXD-U00 which only operates the valve using an external control signal. The regulation must then be done by another controller.
Valves with reversed flow direction for heat pumps can be supplied on request.
NOTE! Always use a calculation program for the correct choice of valve. Enquire for more information
