Carrier EA03SC210 TXV Valve

The Carrier EA03SC210 TXV Valve is a critical OEM replacement part designed for precision refrigerant metering in R-22 HVAC systems. As a primary thermostatic expansion valve, the EA03SC210 regulates the flow of liquid refrigerant into the evaporator coil by monitoring superheat, preventing liquid slugging and ensuring the compressor operates within safe parameters. Constructed with a bi-metal body, this valve is engineered for durability and thermal stability across various load conditions. HVAC contractors often utilize this Factory Authorized Part to restore cooling system efficiency in older Carrier, Bryant, and Payne air conditioners and heat pumps. Proper installation of this internal TXV is essential for maintaining accurate pressure drops and optimizing the heat transfer process. When troubleshooting poor cooling performance or uneven evaporator frosting, replacing a restricted original valve with this genuine Carrier part ensures HVAC compatibility and long-term reliability without the risks associated with generic aftermarket components.

• Optimized Refrigerant Control: Precisely meters R-22 refrigerant to maintain ideal superheat levels and system balance.
• OEM Precision: Guaranteed direct-fit replacement for Carrier EA03SC210, eliminating the need for field modifications.
• Compressor Protection: Prevents unevaporated liquid refrigerant from returning to the suction line, extending the life of original equipment.
• Robust Construction: Features a high-grade bi-metal design to withstand high-pressure fluctuations and environmental stressors.

What refrigerant is the EA03SC210 compatible with?
This valve is specifically calibrated for R-22 refrigerant systems and should not be used with R-410A due to different pressure and flow requirements.

How do I verify if this TXV fits my specific Carrier unit?
Compatibility is determined by the model and serial number of your evaporator coil or outdoor unit. This valve is a common metering device for Carrier/Bryant/Payne residential split systems.

Can this valve be used for both air conditioners and heat pumps?
Yes, the Carrier EA03SC210 is designed to handle the bidirectional flow requirements often found in heat pump applications, providing stable performance in both heating and cooling modes.
