Carrier EA02DZ517 Expansion Valve

The Carrier EA02DZ517 Thermal Expansion Valve is a critical metering device engineered for precise refrigerant control in residential and commercial HVAC systems. This OEM Carrier TXV is the direct replacement for the obsolete EA02DZ515, ensuring a seamless drop-in fit for older units without the need for extensive piping modifications. Designed specifically for R-22 refrigerant systems, it utilizes a bi-metal composition and a sweat/braze connection to maintain a hermetic seal under high-pressure conditions. By accurately modulating the flow of refrigerant into the evaporator, the EA02DZ517 prevents liquid slugging and evaporator icing, maximizing heat transfer efficiency and protecting the compressor from premature failure. As a veteran-grade HVAC replacement part, this thermostatic expansion valve provides the reliability required for 48TJD series units and similar high-demand cooling applications.

• Direct Compatibility: Engineered as the official successor to EA02DZ515, eliminating guesswork during field service.
• System Efficiency: Precision-calibrated to maintain optimal superheat, reducing energy consumption and system wear.
• Robus Connection: Features sweat or braze connection points for a leak-resistant, professional-grade installation.
• R-22 Optimization: Tailored specifically for R-22 refrigerant, ensuring reliable performance in existing legacy systems.
• Compressor Protection: Advanced metering technology prevents liquid carryover, significantly extending the life of the compressor.

• Is the EA02DZ517 a direct fit for the EA02DZ515? Yes, this is the designated manufacturer replacement and maintains the same form factor and technical specifications as the original EA02DZ515.
• What connection method is required for installation? This valve is designed for braze or sweat connections; always ensure proper nitrogen purging during the brazing process to avoid internal oxidation.
• Is this valve compatible with R-410A? No, the Carrier EA02DZ517 is specifically calibrated for R-22 refrigerant systems. Using it with unapproved refrigerants will lead to system failure.
