Description
The Trane VAL9912 is a factory-engineered thermostatic expansion valve (TXV) designed for precise refrigerant flow control in R-410A cooling systems. Rated for 4-ton capacity, this valve meters refrigerant into the evaporator coil to maintain optimal superheat, improving system efficiency, protecting the compressor, and extending equipment life.
Key Features
- Designed specifically for R-410A refrigerant systems
- 4-ton (48,000 BTU/hr) capacity rating
- 3/8″ ODF liquid line inlet connection
- 1/2″ ODF suction/equalizer connection
- Maintains precise superheat for maximum system efficiency
- Protects the compressor from liquid slugging
- Genuine Trane OEM replacement part
- Direct drop-in replacement for compatible Trane systems
How a TXV Works
A thermostatic expansion valve automatically regulates the flow of liquid refrigerant entering the evaporator coil based on the superheat of the suction gas leaving the coil. By maintaining the correct superheat level, the TXV ensures the evaporator operates at peak efficiency under varying load conditions — preventing both flooding and starving of the coil.
Applications
- Trane residential and light commercial split-system air conditioners
- R-410A compatible cooling and heat pump systems
- 4-ton evaporator coil assemblies requiring OEM TXV replacement
