The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level for efficient heat exchange and compressor protection. This valve is a direct OEM-style replacement designed for use in multi-poise indoor air handler configurations. HVAC technicians install this component during refrigerant-side repairs, system commissioning, or when an existing TXV shows signs of hunting, restricted flow, or failure to maintain proper superheat.\u003c\/p\u003e\n\u003cp\u003eThis TXV is intended for use in residential split-system applications where a multi-poise indoor air handler serves as the indoor unit. The valve is specified for the B5BM-X42K-B and B5VM-X42K-B multi-poise indoor air handler models under the B5BM and B5VM model families. It is suited for installations where R-410A is the system refrigerant and the cooling capacity falls at 3.5 tons.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for 3.5-ton cooling capacity in R-410A systems\u003c\/li\u003e\n  \u003cli\u003eCompatible with B5BM-X42K-B and B5VM-X42K-B multi-poise indoor air handlers\u003c\/li\u003e\n  \u003cli\u003eMeters refrigerant flow to maintain proper evaporator superheat\u003c\/li\u003e\n  \u003cli\u003eOEM-specified replacement for B5BM and B5VM model families\u003c\/li\u003e\n  \u003cli\u003eDesigned for R-410A refrigerant — not compatible with legacy refrigerants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified for use on the B5BM-X42K-B and B5VM-X42K-B multi-poise indoor air handlers under the B5BM and B5VM model families.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTXV replacement must be performed by an EPA Section 608 certified HVAC technician. Recover all system refrigerant before opening the refrigerant circuit. Proper TXV orientation and bulb placement are critical to correct superheat sensing — refer to the equipment manufacturer service literature for bulb mounting location and insulation requirements. Recharge the system to manufacturer specifications after installation and verify superheat and subcooling readings before returning the unit 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\u003eCooling Capacity\u003c\/strong\u003e: 3.5 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Thermal Expansion Valve (TXV)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Multi-Poise Indoor Air Handler\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: 669567R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284092780850,"sku":"669567R","price":137.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277995.jpg?v=1781068365","url":"https:\/\/voomisupply.com\/products\/westinghouse-669567r-txv-r-410a-3-5-ton-air-handler","provider":"Voomi Supply","version":"1.0","type":"link"}
