Reznor 220553 Valve

For service professionals maintaining light commercial and residential Reznor cooling equipment, the Reznor 220553 Thermal Expansion Valve is a critical 3-ton TXV designed to optimize refrigerant metering and evaporator performance. Built to handle the rigorous demands of HVAC refrigeration systems, this genuine Reznor replacement part features 5/8" x 5/8" connections, ensuring a precise fit and reducing the risk of leaks during field installation. By accurately modulating the flow of refrigerant based on the heat load, this expansion valve prevents evaporator flooding and compressor slugging, which is essential for maintaining high system efficiency in rooftop units and split systems. As a veteran-grade OEM HVAC part, it provides the reliability needed for low-ambient cooling and variable load conditions, making it a staple for any contractor's service truck when troubleshooting superheat issues or restricted refrigerant flow.

• Optimized Metering: Delivers precise refrigerant control to maintain exact superheat levels, improving total system SEER ratings.
• Durable Construction: Engineered to withstand the pressure fluctuations inherent in 3-ton HVAC systems.
• Direct OEM Fit: Eliminates the guesswork of universal valves with standard 5/8" connections for faster TXV replacement.
• Equipment Protection: Actively prevents liquid refrigerant from reaching the compressor, extending the life of the entire cooling circuit.
