The TXV meters liquid refrigerant into the evaporator coil, maintaining the correct superheat level to protect the compressor and sustain system efficiency. This part is serviced and replaced by licensed HVAC technicians as part of refrigerant-side diagnostics, coil replacement, or system retrofits involving R-410A-compatible equipment.\u003c\/p\u003e\n\u003cp\u003eThis expansion valve is suited for residential and light-commercial HVAC systems that operate on R-410A refrigerant. It is a direct OEM replacement for NORDYNE INTERTHERM branded equipment where the original TXV has failed, lost metering control, or developed a refrigerant leak. Technicians typically encounter this valve during high superheat troubleshooting, inefficient cooling calls, or compressor failure investigations where the metering device is identified as the root cause.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for use with R-410A refrigerant systems\u003c\/li\u003e\n  \u003cli\u003eReplaces the original OEM thermostatic expansion valve in NORDYNE INTERTHERM equipment\u003c\/li\u003e\n  \u003cli\u003eMeters refrigerant flow to maintain proper evaporator superheat\u003c\/li\u003e\n  \u003cli\u003eOEM replacement part ensuring correct fit and function without field modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement thermostatic expansion valve for NORDYNE INTERTHERM R-410A split-system and packaged HVAC equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by an EPA Section 608 certified HVAC technician, as this component is part of the sealed refrigerant circuit. The system must be fully recovered and depressurized before removing the existing TXV. Braze or flare connections should be made per manufacturer and local mechanical code requirements. After installation, the system must be evacuated, leak-checked, and recharged to the equipment nameplate specification before returning to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e: R-410A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Thermostatic Expansion Valve (TXV)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORDYNE INTERTHERM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 669564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Nordyne Intertherm","offers":[{"title":"Default Title","offer_id":51138526609714,"sku":"669564","price":57.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/669564.jpg?v=1778258509","url":"https:\/\/voomisupply.com\/products\/nordyne-intertherm-669564-expansion-valve-r-410a","provider":"Voomi Supply","version":"1.0","type":"link"}
