Trane VAL2378 TXV
The Trane VAL2378 TXV is a critical OEM thermostatic expansion valve engineered for R-22 refrigerant systems with a 5-ton nominal capacity. This straight-through configuration features a 1/2-inch inlet and a 7/8-inch outlet, providing precise superheat control to prevent liquid slugging and ensure optimal evaporator coil performance. As a veteran-grade refrigerant metering device, the VAL2378 includes a 5-foot capillary tube for flexible remote bulb placement, allowing for accurate sensing of suction line temperatures. Designed to meet the exact pressure drop requirements of 5-ton Trane air handlers and split systems, this thermal expansion valve maintains system stability across varying thermal loads. For contractors performing retrofits or repairs, utilizing this Trane replacement TXV ensures localized pressure regulation and protects the compressor by maintaining balanced refrigerant flow. Whether you are troubleshooting inconsistent superheat or a starving evaporator, the Trane VAL2378 provides the reliability required for high-demand residential and light commercial cooling applications.
Key Benefits:- Precise Superheat Regulation: Optimized for R-22 refrigerant to maintain peak efficiency and prevent compressor floodback.
- OEM Compatibility: Genuine Trane VAL2378 ensures seamless fitment with 5-ton air handlers and evaporator coils.
- Extended Capillary Reach: Features a 5-foot capillary tube to accommodate varied suction line configurations and sensing bulb orientations.
- Heavy-Duty Construction: Built to withstand commercial-grade operational pressures in 1/2" x 7/8" line sets.
- What are the symptoms of a failing Trane VAL2378 TXV? Common indicators include a frozen evaporator coil, high superheat readings, or the compressor short-cycling due to restricted refrigerant flow.
- Does this valve work with R-410A systems? No, this expansion valve is specifically calibrated for the pressure-temperature characteristics of R-22 systems.
- Can this be used on a 4-ton system? This valve is rated for 5-ton capacity; using it on lower-tonnage systems may lead to hunting or improper superheat control.
