Trane VAL2946 TXV

The Trane VAL2946 is a professional-grade 2-ton thermal expansion valve designed specifically for R-22 refrigerant systems. Engineered with an angle-body configuration, this TXV features a 3/8-inch ODF inlet and a 1/2-inch ODF outlet, facilitating reliable refrigerant flow regulation in residential and light commercial split systems. The thermal-actuated sensor bulb and 30-inch capillary tube provide precise superheat control, protecting the compressor from liquid slugging while preventing evaporator coil freeze-ups. Built with a stainless steel body and rated for pressures up to 500 PSI, this OEM Trane expansion valve ensures optimal heat transfer efficiency across the "A" coil, maintaining consistent indoor humidity and temperature levels for aging R-22 equipment.

• Precise Superheat Regulation: External sensing bulb monitors suction line temperature to modulate flow, maximizing evaporator efficiency.
• Angle Body Design: Offset 3/8" x 1/2" connections allow for versatile installation in tight air handler cabinets.
• System Protection: Actively manages mass flow to prevent compressor flooding and reduces stress on the refrigeration cycle.
• Direct OEM Replacement: Replaces legacy part numbers like VAL02946, ensuring exact mechanical fit and performance matching.

What are the symptoms of a failing VAL2946 TXV?
Common indicators include frost buildup on the evaporator coil, inconsistent cooling (warm air from vents), and high discharge pressure. If the valve sticks closed, the system may exhibit low suction pressure and short-cycling.

Is this valve compatible with R-410A systems?
No. This valve is calibrated strictly for R-22 refrigerant. Using it with a different refrigerant will lead to improper metering and potential compressor damage.

Does this TXV require a hard start kit?
If installed with a reciprocating compressor, a hard start kit is highly recommended to assist the motor during the pressure equalization phase of the startup cycle.
