Q: Show how the TXV works inside. A Thermostatic expansion valve, TXV, sometimes called TEV, uses 4 forces to adjust the metering passage size and refrigerant flow into the evaporator to maintain a constant superheated vapor value at the end of the evaporator. It's not controlling the suction pressure or the suction line temperature alone. It's controlling the superheat, a value that takes into account both of those. A pin inside the valve slightly moved up and down to change the opening size of

This detailed diagram illustrates the internal structure and function of a thermostatic expansion valve (TXV), a key metering device in refrigeration and air conditioning systems. The valve controls refrigerant flow from the high-pressure liquid line (from the condenser) to the low-pressure expansion line leading to the evaporator, where the refrigerant changes into a boiling liquid/vapor mixture. The TXV comprises a body, piston (orifice), retainer, and flare nut for assembly. The thermostatic
