    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.

    How many times must one fix something before it is fixed?

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