Carrier EA02SC210 TXV

The Carrier EA02SC210 Thermostatic Expansion Valve is a 15-ton capacity component designed for precise refrigerant metering in high-capacity HVAC systems. Featuring 5/8" x 1 3/8" ODF solder connections, this balanced port TXV maintains the correct evaporator superheat across varying load conditions, preventing liquid slugging and protecting the compressor. Engineered for R-410A refrigerant systems, the EA02SC210 utilizes an external equalizer to compensate for pressure drops through the evaporator coil. This Carrier replacement expansion valve is a critical HVAC service part for commercial air handlers and rooftop units where maintaining optimal thermal efficiency is required. Its robust construction ensures long-term reliability in demanding environments, providing the precise subcooling control needed for commercial HVAC cooling cycles. When performing a TXV replacement, ensure proper brazing techniques are used with a heat sink to protect the internal power assembly and diaphragm.

Key Benefits

• Precise Superheat Control: The balanced port design provides stable operation even during significant head pressure fluctuations.
• Optimized System Efficiency: Maintains the ideal refrigerant flow rate to maximize the heat transfer capability of the 15-ton evaporator coil.
• Direct OEM Fit: Exact physical specifications for Carrier EA02SC210 ensure seamless integration without the need for piping modifications.
• Enhanced Reliability: Heavy-duty construction resists vibration and thermal stress common in large-scale commercial refrigeration and AC units.

Common Questions

Is the EA02SC210 compatible with R-22 systems?
No, this specific thermal expansion valve is calibrated for the pressure-temperature characteristics of R-410A refrigerant. Using it with R-22 will result in improper metering and potential system damage.

Does this valve include the sensing bulb?
Yes, the power assembly and sensing bulb are integrated. Always ensure the bulb is mounted on a horizontal suction line at the 4 or 8 o’clock position and properly insulated for accurate temperature sensing.

What are the connection sizes for this 15-ton TXV?
The inlet is a 5/8" ODF (Outer Diameter Female) sweat connection, and the outlet is 1 3/8" ODF, designed for standard copper refrigerant lines.
