The TXV also needs a proper pressure drop (about 100 PSI); without that pressure drop, the TXV can’t do its job properly. When the suction pressure is low, the technician should take the subcooling and superheat inside and outside. The goal is to look for the temperature differences between the inside and outside measurements.Jul 27, 2022 · The remote bulb is the TXV's feedback mechanism that gives the valve an indication of the evaporator superheat and is the only opening force in a TXV. It is usually connected to the suction line with brass straps with bolts and nuts for strength, which prevents any heaving and breakage if water gets between the bulb and suction line and freezes. valve is set in the "0" position.
