Ensure terminal superheat accuracy with the Heil Quaker ICP 1066042 TXV, a professional-grade OEM replacement thermal expansion valve designed for 2-ton HVAC systems. This non-bleed check valve is engineered for precise refrigerant flow control in residential air conditioning and heat pump applications, particularly across International Comfort Products (ICP) brands including Heil, Tempstar, and Comfortmaker. Featuring a 3/8" x 1/2" ODF sweat connection and a 24-inch capillary tube, this valve provides the responsive modulation required to prevent evaporator coil freezing and maintain optimal system efficiency under varying thermal loads.

For service technicians, the ICP 1066042 is the standard for R-410A refrigerant management in compatible split system units. Its non-bleed design ensures that the valve remains closed during the off-cycle, preventing refrigerant migration and protecting the compressor from liquid slugging upon startup. Utilizing this OEM expansion valve eliminates the performance inconsistencies often associated with universal aftermarket alternatives, ensuring the system hits targeted subcooling and superheat parameters exactly as specified by the manufacturer.

• OEM Compatibility: Exact drop-in replacement for ICP 1066042, ensuring fitment in Heil Quaker and Arcoaire 2-ton coils.
• Precision Metering: Maintains consistent evaporator superheat to maximize heat transfer and energy efficiency.
• System Protection: Non-bleed check functionality prevents liquid migration, extending the life of the HVAC compressor.
• Robust Construction: Features a durable 24-inch capillary and ODF sweat connections for reliable, leak-free installation.

Is this TXV compatible with R-22 systems?
No, this specific model is designed for R-410A refrigerant systems. Using it with R-22 will result in improper metering and potential system failure.

Can I use this on a 3-ton unit?
This valve is strictly rated for 2-ton cooling capacity. Undersizing the TXV will starve the evaporator, leading to high superheat and compressor overheating.

What is the purpose of the non-bleed check feature?
The non-bleed design prevents high-side pressure from equalizing to the low-side during the off-cycle, which improves efficiency but requires a hard-start kit on certain single-phase compressors.
