Trane VAL8576 TXV

The Trane VAL8576 is a professional-grade 3 Ton mechanical TXV engineered for high-pressure R-22 air conditioning and heat pump systems. Featuring a 500 PSI working pressure rating and a VX100A charge code, this thermostatic expansion valve ensures precise refrigerant metering across the evaporator coil to maintain optimal superheat levels. Ideal for replacing stalled or hunting valves, the VAL8576 provides a direct fit for Trane original equipment. It is technically identical to D801527P01 and 60L29, ensuring seamless cross-compatibility for field service. Built with a durable thermal actuator and copper flare connections, this valve is designed to handle rigorous duty cycles while preventing coil freeze-ups and compressor liquid slugging. For technicians, installing this genuine OEM Trane expansion valve ensures the system returns to factory-specified cooling efficiency and reliability.

• Precise Superheat Control: Maintains consistent 6°F to 14°F superheat for peak evaporator efficiency.
• High Pressure Rating: Rated for 500# applications to ensure stability in demanding environments.
• OEM Compatibility: Cross-references directly with Trane D801527P01 and 60L29.
• Durable Construction: High-grade copper body with mechanical thermal sensing bulb for long-term accuracy.
• System Protection: Effectively prevents refrigerant underfeeding and overfeeding to protect the compressor.

Is the VAL8576 compatible with R-410A systems?
No, this specific valve is designed and charged for R-22 refrigerant systems. Using it with R-410A will lead to incorrect suction pressures and potential system failure.

What are the symptoms of a failing 3-ton TXV?
Common signs include low suction pressure with high superheat (failed closed), frost on the evaporator inlet, or flood-back to the compressor (failed open).

Can I replace just the power head on this valve?
While some valves allow component-level repair, it is recommended to replace the entire VAL8576 assembly to ensure the internal orifice and sensing bulb are perfectly matched for performance.
