Trane VAL10371 TXV

The Trane VAL10371 TXV is a 4-ton thermostatic expansion valve designed for R-410A refrigeration circuits in compatible Trane HVAC equipment. This R-410A thermostatic expansion valve uses a 3/8-inch ODF inlet and 1/2-inch ODF outlet connection for brazed installation at the evaporator coil.

The valve meters liquid refrigerant into the evaporator to maintain proper coil feeding and stable superheat as system load changes. The VAL10371 is a non-adjustable 4-ton R-410A expansion valve designed for proper refrigerant control in applicable Trane systems.

For service technicians replacing a restricted, damaged, or improperly feeding metering device, the Trane 4-ton TXV provides the specified refrigerant-control configuration for compatible equipment. Before installation, verify the complete unit model, refrigerant type, nominal circuit capacity, and connection sizes. Do not select a TXV by tonnage alone.

• Designed for R-410A refrigerant
• Nominal capacity: 4 tons
• 3/8" ODF inlet x 1/2" ODF outlet
• Non-adjustable TXV configuration
• Controls refrigerant flow into the evaporator as system load changes
• Helps maintain proper evaporator feeding and system superheat

Common Question

Is the Trane VAL10371 compatible with every 4-ton R-410A Trane system?

No. Matching the 4-ton capacity and R-410A refrigerant does not automatically confirm compatibility. Verify the equipment model, refrigeration circuit, original valve part number, and 3/8" ODF inlet x 1/2" ODF outlet connections before ordering.

What does the VAL10371 TXV do?

The TXV meters R-410A refrigerant entering the evaporator coil according to operating conditions, helping maintain proper coil feeding and controlled superheat while reducing the risk of an underfed or overfed evaporator.
