Description
AAON V22120 Thermostatic Expansion Valve (TXV)
The AAON V22120 is an OEM thermostatic expansion valve (TXV) designed as a direct replacement for compatible AAON commercial HVAC systems. Thermostatic expansion valves are critical refrigeration components that precisely meter refrigerant flow into the evaporator coil, maintaining optimal superheat levels and maximizing system efficiency. Replacing a worn or faulty TXV with a genuine AAON part ensures your equipment continues to operate at factory-specified performance levels.
Key Features
- Genuine AAON OEM replacement thermostatic expansion valve
- Precisely meters refrigerant flow to maintain optimal evaporator superheat
- Direct drop-in replacement for compatible AAON rooftop and commercial HVAC units
- Engineered to OEM specifications for reliable, long-term performance
- Helps restore and maintain peak system efficiency and cooling capacity
- Reduces the risk of compressor damage caused by refrigerant flooding or excessive superheat
Application
The V22120 TXV is intended for use in AAON commercial HVAC equipment. Always consult your equipment’s service manual or contact AAON technical support to confirm compatibility with your specific unit model before installation.
Why Replace Your TXV?
A failing thermostatic expansion valve can cause a range of system problems including reduced cooling capacity, high superheat, compressor overheating, and inefficient operation. Installing a genuine AAON replacement TXV restores proper refrigerant metering and protects downstream components, including the compressor.
Installation Note
TXV replacement should be performed by a licensed HVAC/R technician. Proper evacuation, leak testing, and refrigerant handling procedures must be followed in accordance with local codes and EPA regulations.
