Trane VAL9891 Thermal Expansion Valve 48-44 PSI R-22 3Ton

The Trane VAL9891 Thermal Expansion Valve is an essential part of the Trane air conditioning system, a pressure regulating valve that controls refrigerant flow and enhances cooling in residential applications. While the standard type of valve is the on/off valve, the TXV is not only useful but vital in determining the efficiency of the system as well as its protection. In use of a thermal actuator, the valve regulates the quantity of refrigerant charge that is allowed into the evaporator coil depending on its temperature. The valve has threaded ends for easy connection and is designed to last long to work under a pressure range of 48/44 PSI.
