Designed for systems operating on R-134a refrigerant, this valve meters liquid refrigerant based on suction-side superheat feedback, preventing flood-back while maximizing system efficiency. The inlet connection is 3\/8 inch SAE, with a 1\/2 inch and 1\/4 inch ODF outlet configuration. Licensed HVAC technicians handling refrigerant service and system commissioning will find this valve suited for direct installation in R-134a refrigeration circuits.\u003c\/p\u003e\n\u003cp\u003eThis TXV is intended for use in R-134a refrigerant systems where accurate superheat regulation is required. Typical applications include light commercial refrigeration and HVAC systems that rely on R-134a as the working fluid. The valve is installed in the liquid line ahead of the evaporator inlet and works in conjunction with the external equalizer line and remote bulb sensor to respond to changing load conditions. It is appropriate for both new installations and service replacements in systems using this refrigerant.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRegulates refrigerant flow rate into the evaporator for stable system operation\u003c\/li\u003e\n  \u003cli\u003eControls superheat at the evaporator outlet to protect the compressor from liquid flood-back\u003c\/li\u003e\n  \u003cli\u003eCompatible with R-134a refrigerant systems\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch SAE inlet connection with 1\/2 inch and 1\/4 inch ODF outlet ports\u003c\/li\u003e\n  \u003cli\u003eDesigned for direct replacement and new-installation use in refrigeration and HVAC circuits\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 R-134a refrigerant systems requiring a 3\/8 inch SAE x 1\/2 inch x 1\/4 inch ODF valve configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by an EPA Section 608 certified HVAC technician qualified to handle R-134a refrigerant. Recover all system refrigerant and relieve system pressure before cutting into the liquid line to install or replace this valve. Ensure the remote bulb is properly secured to the suction line and insulated to obtain accurate superheat readings. Follow the equipment manufacturer guidelines and applicable mechanical codes when routing the external equalizer line and completing the brazed or flare connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant\u003c\/strong\u003e: R-134a\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 3\/8 inch SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: 1\/2 inch x 1\/4 inch ODF\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: DIVERSITECH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TXVHE-134A-4S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIVERSITECH","offers":[{"title":"Default Title","offer_id":68655525790002,"sku":"TXVHE-134A-4S","price":76.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76e61475566b8d96973f1c5e529341bd.jpg?v=1794498388","url":"https:\/\/voomisupply.com\/products\/diversitech-txvhe-134a-4s-txv-r-134a-expansion-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
