What Is a TXV Assembly?
A thermostatic expansion valve (TXV) is a critical refrigeration component that regulates the flow of refrigerant into the evaporator coil. By responding to suction line temperature and pressure, the TXV ensures the evaporator operates at peak efficiency — preventing both flooding and starvation of the coil. A properly functioning TXV assembly is essential for maintaining system capacity, protecting the compressor, and achieving rated energy efficiency.
Applications
- Trane residential and light commercial HVAC systems
- Compatible with systems requiring Trane OEM TXV replacement
Why Choose OEM Trane Parts?
Using genuine Trane OEM components like the VAL10209 ensures compatibility, maintains equipment warranties, and delivers the performance specifications your system was designed around. Aftermarket substitutes may not meet the precise flow and pressure ratings required for optimal operation.
Trust Jackson Systems to supply the genuine Trane parts you need to keep your equipment running at peak performance.
