The TXV meters liquid refrigerant into the evaporator coil based on superheat, maintaining efficient heat transfer across a range of load conditions. This valve is a direct OEM replacement component installed by licensed HVAC technicians during system servicing or refrigerant-side repairs. It plays a critical role in system efficiency and proper coil operation.\u003c\/p\u003e\u003cp\u003eThis TXV is intended for use in residential and light-commercial cooling and heat pump applications where precise refrigerant metering is required. It is suited for split-system air conditioners and heat pumps that rely on a TXV rather than a fixed orifice metering device. Technicians typically install or replace this valve when superheat readings are out of range, the valve is stuck open or closed, or the coil is showing signs of flooding or starving. Specific compatible model numbers were not provided in the product data.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM replacement TXV for NORDYNE INTERTHERM equipment\u003c\/li\u003e\n\u003cli\u003eRegulates refrigerant flow based on evaporator superheat\u003c\/li\u003e\n\u003cli\u003eSupports efficient heat transfer and stable coil operation\u003c\/li\u003e\n\u003cli\u003eDirect fit replacement reduces field modification time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement TXV for NORDYNE INTERTHERM residential and light-commercial HVAC systems.

Recover all system refrigerant and relieve system pressure before removing the existing valve. Verify the replacement valve orientation and bulb placement match the original installation to ensure accurate superheat sensing. After installation, recharge the system to manufacturer specifications and confirm superheat and subcooling readings are within acceptable range before returning the unit to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Thermostatic Expansion Valve (TXV)\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 669556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Nordyne Intertherm","offers":[{"title":"Default Title","offer_id":51138736947506,"sku":"669556","price":57.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/669556.jpg?v=1778262781","url":"https:\/\/voomisupply.com\/products\/nordyne-intertherm-669556-txv-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
