Replace the control valve with an electronic expansion valve?
Thread Content
On a whim, I wondered whether electronic expansion valves used in the refrigeration industry could replace control valves in certain applications within the chemical industry In some systems, Fisher’s control valves are used in place of electronic expansion valves in refrigeration systems, so I haven’t noticed any difference between the two. I was just thinking about using a reverse substitution?
The expansion valve in the refrigeration industry is a self-acting pressure reducing valve, and it is used in many places
The self-acting pressure reducing valve is also a type of control valve
An electronic expansion valve cannot be considered self-acting; a thermal expansion valve can just barely be considered such. Apart from the refrigeration field, have you seen electronic expansion valves used in any other fields?

In the refrigeration industry, an electronic expansion valve is essentially a temperature control valve; the only difference lies in its actuator. Small refrigeration systems generally use thermal expansion valves or electronic expansion valves, while larger systems with larger pipe diameters employ control valves. You can compare them
Looking at its structure, it’s actually an electronic throttle valve
