    By chance was this valve on the indoor coil of a heat pump having a recip compressor?

    Never seen that before. I would think there has to be an abnormal amount of virbration to shake these parts apart. I don't believe the complete weld would break popping off the power assembly.
    Just a thought take a good look of the system. There may be somthing going on !

    How to make the perfect "Half-Hitch" knot or any other boyscout knot in 3 easy steps...

    1. Remove your meter leads from the meter and very carefully return them to their storage case or bag.
    2. Wait 2 seconds
    3. Very carefully remove your meter leads from their storage place and enjoy your new knot!

    Having been a TEV product mangler in my past life, yes I've seen this before. It is not common, however.

    With a heat pump system in the heating mode, and if a TEV is used to feed the indoor coil, discharge pressure will be transmitted to the underside of its diaphragm via the equalizer line.

    Normally this is not a problem for the valve.

    But if a recip compressor is being used, and if the recip compressor is delivering an inordinate amount of discharge pulsations... these pulsations work on the TEV powerhead. The powerheat casing flexes ever so slightly with these pulsations as if it were a drum. The weld succumbs...

    I don't ever recall this happening when a scroll compressor is used.

    That's just the pressure relief valve doing its job.
