Trane VAL6375 TXV

The Trane VAL6375 is a high-precision 1-ton thermal expansion valve engineered for professional-grade R-22 refrigerant systems. This OEM Trane TXV features 3/8-inch x 3/8-inch mechanical fittings, facilitating a straightforward installation on standard air handlers and evaporator coils. As a critical component for maintaining system superheat, the VAL6375 uses a brass-body design and a sensitive thermal actuator to regulate refrigerant flow based on evaporator load. This ensures the 12,000 BTU/hr capacity is utilized effectively, preventing liquid slugging and optimizing subcooling in residential and light commercial units. For contractors performing a TXV replacement, this non-bleed valve provides the reliability necessary to restore factory-spec cooling performance. The precise metering capability of this thermostatic expansion valve is essential for vintage R-22 HVAC repair jobs where efficiency and component longevity are the primary objectives.

Common Questions

Is the Trane VAL6375 compatible with R-410A systems?
No, this valve is specifically designed and calibrated for R-22 refrigerant. Using it with R-410A will result in incorrect pressure regulation and potential system failure.

Do I need to wrap the valve body during installation?
While the VAL6375 uses mechanical fittings, if any brazing is required near the valve, a wet rag must be used to protect the internal diaphragm and thermal element from heat damage.

Does this valve include the sensing bulb?
Yes, this thermal expansion valve includes the integrated sensing bulb and capillary tube required to monitor suction line temperature for flow adjustment.
