Carrier EA02DZ484 TXV

The Carrier EA02DZ484 is a precision-engineered 12-ton thermostatic expansion valve (TXV) designed for high-capacity light commercial and industrial HVACR systems. Specifically calibrated for R22 and R407C refrigerants, this TGEX series expansion valve ensures stable evaporator superheat by modulating refrigerant flow based on heat load. This Carrier OEM replacement part features a 5/8-inch ODF inlet and a 1 1/8-inch ODF outlet, providing a direct drop-in replacement for EA02DZ486. The hermetic design and integrated sensing bulb allow for consistent performance in various mounting orientations, minimizing the risk of liquid slugging and protecting the compressor. For technicians servicing legacy 12-ton units, the EA02DZ484 is the standard for maintaining original equipment efficiency and system balance.

• Direct Compatibility: Engineered as the specific replacement for EA02DZ486, ensuring exact fit and manifold alignment.
• Dual Refrigerant Support: Factory-set for R22/R407C applications, eliminating the need for field recalibration during refrigerant transitions.
• Optimized Flow Control: The 12-ton capacity rating provides high-precision metering for large-scale evaporators and chillers.
• System Reliability: Features a durable power head assembly and stainless steel capillary for long-term resistance to vibration and thermal stress.

Is the Carrier EA02DZ484 compatible with R410A systems?
No, this valve is specifically designed for R22 and R407C operating pressures. For R410A applications, a dedicated high-pressure TXV must be used.

Can I use this TXV as a replacement for the EA02DZ486?
Yes, the EA02DZ484 is the direct technical successor to the EA02DZ486, matching its physical dimensions and superheat curves.

What are the connection sizes for this 12-ton valve?
This valve utilizes a 5/8" x 1 1/8" ODF solder connection (ODF), built for secure brazing into standard liquid and suction lines.
