The Trane VAL6385 is a high-performance 5-ton R22 TXV designed for precise refrigerant metering in residential and light commercial split systems. Built for durability and technical accuracy, this thermostatic expansion valve features a 1/2" x 5/8" sweat connection (ODF), ensuring a secure, leak-proof fit when properly brazed into the liquid line. As a critical component for maintaining system superheat, the VAL6385 utilizes an external equalizer with a 1/4" ODF connection to provide responsive feedback from the evaporator outlet, protecting the compressor from liquid slugging while maximizing HVAC system efficiency. Each unit is a genuine Trane OEM replacement part, manufactured to original specifications to ensure seamless compatibility with 5-ton evaporators and air handlers. For contractors managing R22 refrigerant systems, this valve provides the necessary pressure drop and flow regulation to restore cooling capacity and prevent evaporator coil freezing in legacy HVAC repair applications. Key Benefits Optimized Metering: Delivers precise refrigerant flow control to maintain target superheat across varying load conditions. OEM Compatibility: Precision-engineered as a direct Trane replacement part for 5-ton capacity units, reducing field modification time. Robust Construction: Features sweat (ODF) connections for reliable, permanent installation in high-vibration environments. Compressor Protection: Regulates the flow of R22 refrigerant to safeguard the compressor against saturation and overheating. System Performance: Resolves common TXV troubleshooting issues such as inconsistent cooling or high head pressure. Common Questions Is the Trane VAL6385 compatible with R410A systems? No, this specific valve is calibrated exclusively for R22 refrigerant applications. Using it with R410A will lead to improper metering and potential system failure. Does this valve require an external equalizer? Yes, the VAL6385 features a 1/4" ODF external equalizer connection, which is necessary for accurate pressure sensing at the evaporator outlet on 5-ton systems. What are the symptoms of a failing TXV in a 5-ton unit? Typical indicators include a frozen evaporator coil, the compressor running continuously without reaching setpoints, or inconsistent discharge air temperatures.
