Carrier EA36UC080 Expansion Valve

The Carrier EA36UC080 Expansion Valve is a critical OEM thermostatic expansion valve (TXV) designed specifically for high-efficiency HVAC systems utilizing R-410A refrigerant. This bi-metal metering device is engineered to maintain a precise superheat setting, preventing compressor slugging while maximizing evaporator performance. Constructed with a durable brass valve body and a capillary sensing bulb, the EA36UC080 provides the rapid response required for modern fan coil units and heat pumps. By modulating refrigerant flow based on real-time heat load and ambient conditions, this replacement expansion valve ensures consistent cooling capacity and system reliability in demanding commercial and residential environments. For technicians performing HVAC repair or maintenance, using a genuine Carrier part ensures seamless fitment and restores the unit to its original factory specifications, supporting long-term energy efficiency and preventing common issues like refrigerant flooding or starvation in the evaporator coil.

Key Benefits:

• Specifically calibrated for R-410A refrigerant to ensure accurate pressure regulation.
• Robust brass and stainless steel construction for long-term resistance to corrosion and wear.
• Optimizes evaporator coil efficiency by maintaining the ideal refrigerant-to-air heat exchange ratio.
• Features an adjustable superheat setting for fine-tuning system performance during commissioning.
• Direct OEM replacement for precise mechanical compatibility with Carrier, Bryant, and Payne units.

Common Questions:

How do I know if my TXV is failing?
Common symptoms of a faulty Carrier EA36UC080 include high superheat, frost on the evaporator coil, or inconsistent cooling cycles. If you notice "hunting" where the pressures fluctuate wildly, the thermostatic element may no longer be responding correctly.

Is the EA36UC080 compatible with R-22 systems?
No, this expansion valve is engineered specifically for R-410A refrigerant. Attempting to use it in an R-22 system will result in improper metering and potential system damage.

What models does this expansion valve fit?
The EA36UC080 is common in several Carrier 40RU series fan coils and heat pumps, including models 40RUQA16AA1AA and 40RUAA25T. Always verify your specific model number against the technical literature.
