Warning there is audio issues with this video I was unable to correct.
This video we take a deeper look at TXV TEV If your new to TXV TEV start with HVAC 060 introduction to TXV    • HVAC 060 Introduction to the TXV TEV   to to HVAC 065

Here we cut a few open take a peak at why the fail introduce check valves, compare adjustable to non adjustable and compare commercial to residential.

There is still so much more information that is left out of this video. Later I will make one with different failues and how they would respond but I am a ways away from the diagnostics portion.

Below is a list of resources to help cover the details I left out and other view points and ways of explaining the TXV and more.
