Carrier EA02DZ482 TXV

The Carrier EA02DZ482 TXV is a high-capacity 12.5-ton thermostatic expansion valve designed specifically for R22 systems requiring precise refrigerant metering. As a direct OEM replacement for EA02DZ480, this valve ensures seamless integration into existing Carrier, Bryant, and Payne commercial or residential refrigeration units. Featuring 5/8" x 7/8" ODF solder connections, it facilitates a secure, leak-proof installation while maintaining optimal superheat levels across varying load conditions. The thermal expansion valve utilizes a robust brass body and bi-metal composition to withstand high-pressure environments, effectively preventing evaporator coil freezing and liquid slugging. For technicians managing large-scale R22 HVAC systems, transitioning to this updated model ensures consistent evaporator efficiency and protects the compressor by maintaining the correct mass flow of refrigerant. This genuine HVAC expansion valve 12.5 ton rating makes it an essential component for maintaining peak performance in aging high-tonnage infrastructure.

• Direct OEM Compatibility: Serves as the factory-authorized replacement for EA02DZ480, eliminating the need for field modifications.
• Precision Metering: Optimized for R22 refrigerant to provide stable superheat control and prevent refrigerant flooding.
• High Capacity: Engineered for 12.5-ton systems, making it suitable for heavy-duty commercial cooling applications.
• Durable Construction: Features a high-grade brass body with 5/8" x 7/8" ODF connections for reliable, long-term operation under high stress.
• Enhanced System Protection: Integrated strainer helps prevent debris from fouling the internal orifice, extending the life of the cooling circuit.

Is the EA02DZ482 compatible with R410A systems?
No, this specific valve is calibrated exclusively for R22 refrigerant. Using it with R410A will lead to improper metering and potential system failure due to different pressure requirements.

Can I use this to replace a smaller tonnage TXV?
This is a 12.5-ton capacity TXV. It is critical to match the tonnage of the valve to the capacity of your evaporator coil to ensure the system reaches its designed efficiency and maintains proper superheat.

Does this valve include the internal strainer?
Yes, this Carrier EA02DZ482 is equipped with a debris-preventing strainer to protect the internal metering components from contaminants within the refrigerant line.
