The valve uses a Chatleff threaded connection and is rated to AHRI standards. It meters refrigerant flow into the evaporator coil, maintaining the correct superheat to protect the compressor and maximize system efficiency. This TXV is installed in refrigerant coil assemblies and heat pump configurations within the Unico high-velocity mini-duct system. Licensed HVAC technicians handling R-22 systems are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis valve is used on Unico M and V Series units, including the 4260 and 4860 model families, in both refrigerant coil and heat pump applications. Confirmed compatible part numbers include MC4260H and M4860CL1-E. The Chatleff threaded connection is standard to these Unico coil assemblies. It is suited for residential and light-commercial installations where the Unico high-velocity system is the selected air distribution platform.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR-22 refrigerant service, 4-ton capacity\u003c\/li\u003e\n  \u003cli\u003eChatleff threaded connection for direct fitment to Unico coil assemblies\u003c\/li\u003e\n  \u003cli\u003eAHRI-rated for standardized performance verification\u003c\/li\u003e\n  \u003cli\u003eCompatible with both refrigerant coil and heat pump configurations\u003c\/li\u003e\n  \u003cli\u003eDesigned for M and V Series, 4260, and 4860 Unico model families\u003c\/li\u003e\n  \u003cli\u003ePROP 65 warning applicable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on THE UNICO SYSTEM M and V Series units, model families 4260 and 4860, including refrigerant coil part numbers MC4260H and M4860CL1-E, in both refrigerant coil and heat pump applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by an EPA Section 608 certified HVAC technician, as this valve is used in an R-22 closed refrigerant circuit. Recover refrigerant and confirm the system is fully depressurized before disconnecting the existing TXV. Verify Chatleff thread engagement and torque fittings to the coil manufacturer specifications before recharging. After installation, check superheat at the suction line to confirm proper valve operation before returning the system 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-22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 4 ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Chatleff Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: AHRI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Refrigerant Coil, Heat Pump\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Models\u003c\/strong\u003e: M and V Series, 4260, 4860\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Part Numbers\u003c\/strong\u003e: MC4260H, M4860CL1-E\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: THE UNICO SYSTEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: a00808-005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THE UNICO SYSTEM","offers":[{"title":"Default Title","offer_id":51268093313330,"sku":"A00808-005","price":155.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910872.png?v=1780698930","url":"https:\/\/voomisupply.com\/products\/the-unico-system-a00808-005-txv-4-ton-r-22-chatleff","provider":"Voomi Supply","version":"1.0","type":"link"}
