Carrier EA02DZ456 TXV

The Carrier EA02DZ456 is a high-capacity 8-ton thermal expansion valve (TXV) designed for precision refrigerant metering in R22 and R407C HVAC systems. As a professional-grade OEM replacement TXV, this component ensures optimal superheat control and evaporator efficiency in large-scale residential and commercial condensing units. This specific model features a 5/8" sweat inlet and a 1 1/8" sweat outlet, providing a robust fit for high-tonnage applications. Engineered with a 5-foot capillary tube and a remote sensing bulb, the EA02DZ456 delivers responsive pressure regulation to prevent liquid slugging and maintain system stability. This valve serves as the direct replacement for EA02DZ452 and EA02DZ453, making it the standard choice for technicians performing maintenance on legacy Carrier, Bryant, and Payne equipment. Its bi-metal construction and factory-calibrated settings facilitate a streamlined HVAC expansion valve installation while restoring the original performance specifications of 8-ton cooling systems.

• OEM Compatibility: Authentic Carrier HVAC replacement part ensuring exact fit and functional matching for 8-ton systems.
• Versatile Refrigerant Support: Rated for use with both R22 and R407C, supporting legacy repairs and modern retrofits.
• Precision Metering: Equipped with a 5' capillary for accurate temperature sensing and stable refrigerant flow control.
• System Protection: Optimizes the heat transfer process and protects the compressor by maintaining consistent superheat levels.

Is the Carrier EA02DZ456 compatible with R410A systems?
No, this specific thermal expansion valve is calibrated for R22 and R407C pressure-temperature characteristics. Using it with R410A will lead to improper metering and potential system failure.

What are the inlet and outlet connection sizes for this 8-ton TXV?
The valve features a 5/8" inch ODF inlet and a 1 1/8" inch ODF outlet, designed for standard braze/sweat connections in 8-ton cooling circuits.

Can I use this to replace an EA02DZ452 or EA02DZ453?
Yes, the EA02DZ456 is the direct manufacturer-authorized replacement for both legacy part numbers, maintaining the same 8-ton capacity and physical dimensions.
