Description
The Trane VAL21110 is an OEM thermostatic expansion valve (TXV) engineered to deliver precise refrigerant flow control in Trane cooling and heat pump systems. By accurately metering refrigerant into the evaporator coil, this TXV helps maintain optimal superheat levels, protecting the compressor and maximizing system efficiency and comfort.
Key Features
- OEM Trane replacement TXV for direct, reliable fit
- Precise refrigerant metering to maintain optimal evaporator superheat
- Helps protect the compressor from liquid refrigerant slugging
- Supports peak system efficiency and consistent cooling performance
- Built to Trane’s quality and durability standards
Why Replace Your TXV?
A failing thermostatic expansion valve can cause a wide range of system problems, including poor cooling, icing on the evaporator coil, high suction pressure, or compressor damage. Replacing a worn or defective TXV with a genuine Trane VAL21110 restores proper refrigerant metering and helps return the system to factory-specified performance.
