I have two Trane, cooling, non-bleed, single direction flow TXV valves:
Valve A is a TAYTXVA0E3C designed for 3 to 3.5 ton AC units
Valve B is a TAYTXVA0H3C designed for 5 to 6 ton AC units
Both valves have a 3/8 liquid line feed.
Question: I place the temperature sensor bulb of both valves in warm water so each valve is WIDE open. Each valve is being supplied with liquid R-22 from their respective design condensers at the same pressure.
Which valve will allow more R-22 to flow and why?

The H3C will allow more flow.
Why: Because its set up for a larger tonnage unit. If you put E3C TXV on the 5 ton coil you starve the evap.

Valve B. Why? 5Ton vs.3Ton! We need to have a serious talk here about boiling and condensing.Originally posted by wendel
