Compatible with R-404A and R-507 refrigerants, this valve maintains precise superheat levels to protect the compressor and optimize system efficiency. SAE flare connections measuring 0.38 inches, 0.5 inches, and 0.3 inches allow for direct integration into commercial and low-temperature refrigeration systems. Licensed refrigeration technicians install this component as part of routine system servicing or refrigerant circuit upgrades.\u003c\/p\u003e\u003cp\u003eThis TXV is suited for commercial refrigeration applications using R-404A or R-507 refrigerant. Typical installations include walk-in coolers, reach-in display cases, and low-temperature refrigeration equipment where precise refrigerant metering is critical. The valve works within the refrigerant circuit between the liquid line and the evaporator inlet, responding to bulb-sensed evaporator outlet temperature to continuously adjust refrigerant flow and maintain target superheat.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompatible with R-404A and R-507 refrigerants for commercial refrigeration applications\u003c\/li\u003e\n\u003cli\u003eSAE flare connections at 0.38 inches, 0.5 inches, and 0.3 inches for direct field installation\u003c\/li\u003e\n\u003cli\u003eControls refrigerant superheat at the evaporator outlet to protect compressor integrity\u003c\/li\u003e\n\u003cli\u003eRegulates refrigerant flow rate into the evaporator for stable system operation\u003c\/li\u003e\n\u003cli\u003eDesigned as a replacement or upgrade component in low-temperature refrigeration circuits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in refrigeration systems charged with R-404A or R-507 refrigerant, featuring SAE flare connections consistent with standard commercial refrigeration piping configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC-R technician holding an EPA Section 608 certification. Recover all refrigerant and depressurize the system before removing the existing valve. Verify the bulb is properly positioned and secured at the evaporator outlet per the system manufacturer's requirements. After installation, check superheat values to confirm proper valve operation before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: R-404A, R-507\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: SAE Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Sizes\u003c\/strong\u003e: 0.38 inches, 0.5 inches, 0.3 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIVERSITECH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TXVHE-404A-507-14F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIVERSITECH","offers":[{"title":"Default Title","offer_id":68655781609778,"sku":"TXVHE-404A-507-14F","price":76.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76e61475566b8d96973f1c5e529341bd_08474460-711e-41b1-86a5-536ad5c0f51b.jpg?v=1794499116","url":"https:\/\/voomisupply.com\/products\/diversitech-txvhe-404a-507-14f-txv-r-404a-r-507","provider":"Voomi Supply","version":"1.0","type":"link"}
