The TXV meters refrigerant flow into the evaporator coil based on superheat, maintaining efficient heat exchange across the full operating range of the system. This kit is installed by licensed HVAC technicians during new installations, refrigerant system retrofits, or TXV replacements in split-system air conditioning and heat pump applications. At 5 tons of capacity, this valve is sized for larger residential and light commercial systems.\u003c\/p\u003e\u003cp\u003eThis TXV kit is specifically intended for air handler applications running R-410A refrigerant at 5-ton capacity. It is used on the GB5BM model air handler, with the specific applied unit part number 904311GD\/GB5BM-X60K-C. Installation is typical in split-system cooling and heat pump setups where precise refrigerant metering is required to maintain system efficiency and protect the compressor from liquid slugging.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned for R-410A refrigerant systems\u003c\/li\u003e\n\u003cli\u003eSized for 5-ton air handler capacity\u003c\/li\u003e\n\u003cli\u003eFunctions as a metering device controlling refrigerant superheat at the evaporator\u003c\/li\u003e\n\u003cli\u003eKit format includes components needed for a complete TXV replacement or installation\u003c\/li\u003e\n\u003cli\u003eCompatible with both air conditioning and heat pump operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on the WESTINGHOUSE GB5BM model air handler, specifically unit part number 904311GD\/GB5BM-X60K-C.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTXV replacement and installation must be performed by an EPA Section 608 certified HVAC technician. The refrigerant system must be fully recovered and the system de-energized before removing the existing metering device. Proper evacuation to required micron levels is required before recharging with R-410A. Verify superheat and subcooling readings after installation to confirm correct TXV operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e: R-410A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 5 Ton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Conditioning and Heat Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed On Unit Part Number\u003c\/strong\u003e: 904311GD\/GB5BM-X60K-C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed On Model\u003c\/strong\u003e: GB5BM Air Handler\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 920673A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284148420914,"sku":"920673A","price":135.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278097.png?v=1781069800","url":"https:\/\/voomisupply.com\/products\/westinghouse-920673a-txv-kit-r-410a-5-ton-air-handler","provider":"Voomi Supply","version":"1.0","type":"link"}
