Re: Expansion valve?

i was told the same thing in ac class in school about the valves. however the person i talked to at the manufacturer claimed it wouldn't matter because the different characteristics of the refrigerants would cause the valve to act differently. i would personally just continue to use r12 or change the valve if i converted but the guy did make a very technical argument.
