Rated at 3 tons with a 5-ton bulb equivalent, this valve meters refrigerant flow into the evaporator to maintain proper superheat across a range of load conditions. Connections are 3\/8-inch and 1\/2-inch ODF, suitable for sweat installation. It weighs 1.26 pounds. Licensed refrigeration technicians and HVAC-R mechanics are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for low-temperature commercial refrigeration systems operating on R-404A, such as reach-in coolers, walk-in freezers, and display case evaporator circuits. The external equalizer port allows the valve to maintain accurate superheat control in systems where significant pressure drop exists across the evaporator. Typical installations involve evaporator coils in commercial refrigeration equipment where precise refrigerant metering is critical to system efficiency and compressor protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for R-404A refrigerant in low-temperature refrigeration service\u003c\/li\u003e\n  \u003cli\u003e3-ton capacity with 5-ton bulb equivalent for accurate superheat sensing\u003c\/li\u003e\n  \u003cli\u003eExternal equalizer design compensates for evaporator pressure drop\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch and 1\/2-inch ODF sweat connections for standard field installation\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 1.26 pounds for easy handling in tight equipment spaces\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 low-temperature commercial refrigeration systems using R-404A refrigerant with external equalizer evaporator circuits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by an EPA 608-certified technician following applicable refrigeration safety codes. Recover and reclaim all system refrigerant before opening the refrigerant circuit. Sweat connections require proper nitrogen purge during brazing to prevent internal oxidation. Mount the sensing bulb securely to the suction line at the evaporator outlet per standard TXV installation practice, and connect the external equalizer line downstream of the bulb location.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant\u003c\/strong\u003e: R-404A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Low Temperature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Capacity\u003c\/strong\u003e: 3 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBulb Equivalent\u003c\/strong\u003e: 5 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEqualizer Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/8-inch and 1\/2-inch ODF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 1.26 pounds\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: SPORLAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 169421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPORLAN","offers":[{"title":"Default Title","offer_id":51468541919538,"sku":"169421","price":203.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945747.png?v=1783917038","url":"https:\/\/voomisupply.com\/products\/sporlan-169421-txv-external-equalizer-3-ton-r-404a-low-temp","provider":"Voomi Supply","version":"1.0","type":"link"}
