Description
The Trane VAL7237 is an OEM-quality Thermostatic Expansion Valve (TXV) engineered for reliable, precise refrigerant metering in R-22 residential and light-commercial cooling systems rated at 2 tons of capacity. Designed as a direct Trane replacement, this valve helps restore system efficiency and protect the compressor by maintaining optimal superheat levels across varying load conditions.
Key Features
- Refrigerant: R-22
- System Capacity: 2 Ton
- Liquid Line Connection: 3/8″
- Suction Line Connection: 5/8″
- Capillary Tube Length: 30″
- Valve Type: Thermostatic Expansion Valve (TXV)
- OEM Trane replacement part — direct-fit installation
How It Works
The TXV automatically modulates refrigerant flow into the evaporator coil in response to suction-line superheat sensed by the remote bulb and 30″ capillary assembly. By maintaining consistent superheat, the valve maximizes evaporator efficiency, prevents liquid slugging, and extends compressor life — even as indoor load conditions fluctuate.
Applications
- Trane split-system air conditioners and heat pumps using R-22 refrigerant
- Residential and light-commercial cooling systems up to 2 tons
- Retrofit or warranty-replacement applications requiring OEM-spec components
Why Choose the Trane VAL7237?
Using a genuine Trane TXV ensures compatibility with factory-designed refrigerant circuit parameters, simplifying installation and supporting system warranty requirements. The 30″ capillary provides ample reach for remote-bulb placement on the suction line, enabling accurate superheat sensing and stable system control.
