What's Inside a TXV? How Does a Thermostatic Expansion Valve Work?

In this HVACR Training Video, I show How a TEV/TXV Works and How the Thermostatic Expansion Valve Controls Superheat across the Evaporator. Three Pressures are Applied to the TXV and I cut apart several TXVs to show the single rod and pin, two rods, balanced port, bleed port, sealed powerhead, bulb, adjustment for spring pressure, external equalizer, and more!
