The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level to optimize system efficiency and protect the compressor. This unit is rated for R-410A refrigerant at a 2-ton capacity. It also includes an equalized check valve, which allows the system to pressure-equalize on shutdown — a feature that simplifies compressor restart and reduces wear on starting components. Licensed HVAC technicians handle installation as part of a refrigerant-side repair or coil replacement.\u003c\/p\u003e\n\u003cp\u003eThis TXV is intended for indoor installation, mounted at or near the evaporator coil inlet. It is suited for split-system air conditioner applications using R-410A refrigerant in the 2-ton capacity range. The integrated equalized check valve adds functionality without requiring a separate check valve component in the liquid line, making it appropriate for systems where pressure equalization is needed across the metering device. Installation typically occurs during evaporator coil service, TXV replacement for loss of charge control, or system refrigerant conversion work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for R-410A refrigerant at 2-ton capacity\u003c\/li\u003e\n  \u003cli\u003eIndoor thermostatic expansion valve for evaporator coil metering\u003c\/li\u003e\n  \u003cli\u003eIntegrated equalized check valve for pressure equalization on system shutdown\u003c\/li\u003e\n  \u003cli\u003eDirect replacement TXV valve for air conditioner relay systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement indoor TXV for R-410A air conditioning systems rated at 2 tons.

Recover all refrigerant from the system before opening the refrigerant circuit — never vent refrigerant to atmosphere. Ensure the system is fully de-pressurized and the electrical disconnect is open before beginning work. Follow the equipment manufacturer's service instructions and applicable local mechanical codes when brazing, flaring, or connecting refrigerant-side components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Thermostatic Expansion Valve (TXV), Indoor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant\u003c\/strong\u003e: R-410A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 2 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdditional Feature\u003c\/strong\u003e: Equalized Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Conditioner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocation\u003c\/strong\u003e: Indoor (Evaporator Side)\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: WESTINGHOUSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 669564R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284004274482,"sku":"669564R","price":141.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277990.jpg?v=1781065735","url":"https:\/\/voomisupply.com\/products\/westinghouse-669564r-txv-r-410a-2-ton-indoor-ac","provider":"Voomi Supply","version":"1.0","type":"link"}
