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
