Trane VAL7630 TXV

The Trane VAL7630 TXV is a critical metered flow component designed specifically for legacy R-22 refrigerant systems. This 1.5-ton thermostatic expansion valve features a 3/8-inch ODF inlet and a 1/2-inch ODF outlet, engineered to maintain precise superheat and optimize evaporator efficiency in matched Trane and American Standard air handlers. With a 500 PSI maximum working pressure, the VAL07630 ensures stable refrigerant regulation even under high-load conditions, preventing compressor liquid slugging or evaporator starvation.

For technicians performing a Trane expansion valve replacement, this genuine OEM part facilitates a direct-fit installation. It is commonly utilized in residential HVAC 1.5-ton AC units and heat pumps, where maintaining exact refrigerant flow is essential for system longevity. When troubleshooting frozen evaporator coils or erratic suction pressures, replacing the thermal expansion valve is often the necessary path to restoring factory-spec cooling performance and dehumidification in older R-22 equipment.

• Precise Superheat Control: Maintains optimal refrigerant levels in the evaporator to maximize heat transfer.
• OEM Compatibility: Exact replacement for Trane VAL07630, ensuring matched performance with original equipment specs.
• System Protection: Regulates flow to protect the compressor from damage caused by refrigerant flood-back.
• Durable Construction: Rated for 500# pressure applications, providing reliable operation in demanding environments.

Is the Trane VAL7630 compatible with R-410A systems?
No, this valve is specifically calibrated for R-22 refrigerant pressures and flow rates. Using it with R-410A will lead to improper metering and potential system failure.

What are the symptoms of a failing TXV on a 1.5-ton unit?
Common indicators include hunting suction pressures, a frozen evaporator coil, high superheat, or the system failing to reach the temperature setpoint despite the compressor running.

Does this valve include the sensing bulb and mounting hardware?
Yes, as a standard thermal expansion valve kit, it includes the integrated sensing bulb required to monitor suction line temperature for flow adjustment.
