This is a BRAND NEW OEM Trane/American Standard 5 Ton R410A Acoil TXV Valve. It is designed as a OEM replacment for the old part #s listed below. Thanks for looking and good luck!
The thermostatic expansion valve controls one thing only: the rate of flow of liquid refrigerant into the evaporator. This is achieved by monitoring temperature and pressure in the refrigerant system.
