Carrier EA03SC455 TXV Valve

The Carrier EA03SC455 TXV Valve is a high-capacity, 8-ton thermostatic expansion valve engineered for precise refrigerant metering in R-22 air conditioning and heat pump systems. Designed as a direct OEM HVAC replacement part, this bi-metal thermostatic expansion valve ensures stable superheat control across varying load conditions to prevent compressor liquid slugging. Featuring a 5/8-inch ODF inlet and a 1 3/8-inch ODF outlet connection, it accommodates high-flow commercial and residential evaporators. The 60-inch capillary tube provides specialized flexibility for sensing bulb placement on the suction line, ensuring accurate temperature feedback. Integrating this R-22 expansion valve into your kit helps restore system efficiency and maintain optimal subcooling levels. As a veteran-preferred HVAC expansion valve 8 ton solution, the EA03SC455 is built to handle the rigorous pressure demands of professional cooling installations while protecting the recovery life of legacy R-22 equipment.

• Precise Refrigerant Control: Maintains consistent superheat to maximize evaporator coil efficiency and prevent coil freeze-ups.
• 8-Ton Nominal Capacity: Optimized for large-scale residential and commercial R-22 systems requiring high-volume flow.
• Durable Bi-Metal Construction: Engineered for thermal sensitivity and long-term reliability in high-pressure environments.
• Extended Capillary Reach: The 60-inch lead allows for professional sensing bulb mounting in tight or complex cabinet configurations.
• Universal Compatibility: Fits a wide range of Carrier, Bryant, and Payne air handlers and packaged units.

Is the sensing bulb pre-charged?
Yes, the Carrier EA03SC455 features a factory-charged power element and sensing bulb designed specifically for the thermal characteristics of R-22 refrigerant.

Does this valve include the internal strainer?
This OEM TXV is designed with internal mesh protection to catch debris, though installing a new liquid line filter drier is always recommended during replacement.

Will this work with R-410A systems?
No, this specific valve is calibrated for the pressure-temperature profile of R-22 refrigerant. Using it with R-410A will lead to improper metering and potential system damage.
