Trane VAL7574 TXV
The Trane VAL7574 is a professional-grade thermostatic expansion valve (TXV) engineered to maintain precise superheat and refrigerant flow in 2.5-ton HVAC systems. Featuring a 3/8" inlet and 5/8" outlet, this OEM Trane replacement part utilizes a 36-inch capillary tube and a high-sensitivity sensing bulb to react to evaporator load changes, preventing liquid floodback to the compressor while maximizing heat transfer across the coil. Designed for durability and precision, the VAL7574 TXV is compatible with R-410A, R-22, and R-404A refrigerants (verify factory settings) and is a standard component for many WSC Series packaged units and heat pump architectures. For contractors performing a field TXV replacement, ensure proper bulb placement at the 4 or 8 o’clock position on the suction line to maintain accurate thermal feedback and system efficiency.
Key Benefits- Optimized Superheat Control: Automatically adjusts refrigerant metering to prevent evaporator freeze-ups and compressor slugging.
- Heavy-Duty Construction: Features a robust brass valve body and stainless steel internal components for long-term reliability in high-cycle environments.
- 36-Inch Capillary Reach: Provides ample length for secure sensing bulb mounting on various evaporator coil configurations.
- OEM Compatibility: A direct-fit 2.5-ton thermal expansion valve for specific Trane and American Standard air handlers and packaged systems.
- Can this TXV be used with R-410A systems? Yes, the Trane VAL7574 is designed for modern high-pressure refrigerants, but always verify your specific unit's refrigerant type and subcooling requirements during installation.
- What are the symptoms of a failing VAL7574 expansion valve? Common signs include frost on the evaporator coil, high superheat readings, or the outdoor unit short-cycling due to pressure safety trips.
- Does this include the internal strainer? As a standard Trane OEM TXV, it is designed with internal filtration to protect the orifice from debris; however, installing a new liquid line filter drier is recommended upon replacement.
