Description
The Armstrong Furnace H2TXV01-1 is a factory-matched thermostatic expansion valve (TXV) kit engineered for 3-ton residential and light-commercial HVAC systems. Featuring a 30″ capillary tube, this kit provides accurate refrigerant metering to maintain optimal evaporator superheat, improve system efficiency, and protect the compressor from liquid slugging.
Key Features
- Designed for 3-ton (36,000 BTU/hr) system capacity
- Includes 30″ capillary tube for precise thermal sensing
- Factory-matched to Armstrong Furnace coil applications for reliable, drop-in installation
- Thermostatic expansion valve design maintains consistent superheat across varying load conditions
- Helps maximize system efficiency and extend compressor life by preventing liquid refrigerant floodback
- Complete kit format includes all components needed for a straightforward field installation
Why Upgrade or Replace Your TXV?
A properly functioning TXV is critical to system performance. A failing or incorrectly sized valve can cause low suction pressure, high superheat, reduced capacity, and premature compressor failure. The H2TXV01-1 restores factory-specified refrigerant flow control, ensuring your Armstrong system operates at peak efficiency.
Application
- Compatible with Armstrong Furnace evaporator coil assemblies rated at 3 tons
- Ideal for service replacement or new coil installations requiring a TXV metering device
