Trane VAL2376 TXV

The Trane VAL2376 is a professional-grade thermostatic expansion valve (TXV) engineered to maintain precise refrigerant superheat across a wide range of evaporator loads. Designed specifically for 5-ton R22 systems, this valve ensures maximum heat transfer efficiency while protecting the compressor from liquid slugging. The VAL2376 features a 3/8" x 1/2" SAE flare connection, allowing for a reliable mechanical seal without the need for brazing in tight residential or light commercial cabinets.

For technicians servicing older R22 HVAC equipment, this replacement expansion valve provides the exact flow modulation required to restore system capacity. The brass body construction and stainless steel power element are built to handle the high-pressure environment of a liquid line, ensuring stable performance during peak summer demands. When installing the Trane VAL2376 TXV, always ensure the sensing bulb is properly insulated and secured to the suction line to maintain accurate thermal feedback and optimal system balance.

• Precise Superheat Control: Automatically adjusts refrigerant flow to prevent evaporator flood-back and compressor damage.
• OEM Compatibility: Exact replacement for VAL2376 in 5-ton Trane and American Standard air handlers and coils.
• Flared Connections: The 3/8" x 1/2" SAE fittings simplify field replacement and eliminate the risk of heat damage to internal components during installation.
• Optimized for R22: Calibrated specifically for the pressure-temperature characteristics of R22 refrigerant.

Is the Trane VAL2376 compatible with R410A systems?
No, this valve is internally calibrated for the pressure curves of R22 refrigerant only. Using it with R410A will result in improper superheat and potential system failure.

Can I use this TXV on a 3-ton or 4-ton unit?
This is a 5-ton rated TXV. While some valves have a wider operating range, installing an oversized expansion valve can lead to "hunting," where the valve fluctuates and fails to maintain a steady superheat.

Does this valve require an external equalizer line?
Check the specific coil configuration. Most 5-ton Trane applications utilizing this part number are designed for internal or external equalization based on the original equipment’s pressure drop across the distributor.
