Trane VAL7237 TXV
The Trane VAL7237 TXV (OEM part VAL07237) is a high-precision thermostatic expansion valve engineered for 2-ton residential and light commercial cooling systems. Specifically designed for R-22 refrigerant, this metering device maintains tight control over evaporator superheat, preventing liquid slugging and protecting the compressor from damage during high-load conditions. This valve features standard 3/8-inch inlet and 5/8-inch outlet ODS connections for a leak-free braze. The integrated 30-inch capillary tube and sensing bulb provide responsive modulation, ensuring the evaporator coil remains fully active across varying ambient temperatures without flooding.
For service technicians, the Trane VAL7237 serves as a direct drop-in replacement for legacy packaged units and heat pumps, including the WSC series. When diagnosing a starved or hunting evaporator, verify the external equalizer connection and bulb placement on the suction line. This 2-ton R-22 expansion valve is a critical component for restoring original SEER ratings and ensuring stable refrigerant flow in aged systems where head pressures may fluctuate. Always replace the filter drier when opening the circuit to prevent moisture from contaminating the new powerhead assembly.
Key Benefits
- Ensures precise R-22 refrigerant flow to maximize 2-ton system capacity.
- Features a durable 30-inch capillary tube for flexible sensing bulb placement.
- Compatible with a wide range of Trane residential packaged units and air handlers.
- Maintains optimal evaporator superheat to prevent compressor failure.
- Direct OEM replacement part (VAL07237) for exact fit and performance.
Common Questions
Can I use this TXV on a 2.5-ton system if the connections match?
No. This valve is calibrated specifically for a 2-ton capacity. Using it on an incorrectly sized system will cause improper refrigerant metering and likely lead to evaporator freezing or compressor starvation.
How do I tell if my VAL7237 is failing?
A failing TXV typically presents as high superheat (starving) or very low superheat (flooding). Check for frosting at the valve body or huntinng suction pressures on your manifolds to confirm a stuck internal needle or lost powerhead charge.
Is this part compatible with R-407C dry charge systems?
While R-407C has similar pressure characteristics to R-22, this valve is factory-set for R-22. Consultation with the equipment manufacturer is recommended before using this HVAC expansion valve with alternative refrigerants.
