Built from high-quality brass, this valve features a double seal washer and o-ring system using Viton-equivalent materials rated for No. 2 fuel oil and kerosene. The 1\/2 inch MPT inlet connects to the tank fitting, while the 3\/8 inch OD flare outlet connects to the oil supply line. A manual handwheel allows the valve to double as a service valve, eliminating the need for a separate shutoff during routine maintenance. Maximum operating pressure is 10 psi. Licensed oil heat technicians and plumbers perform installation on residential oil heating systems.\u003c\/p\u003e\n\u003cp\u003eThe 12620 is intended for residential oil heating installations where a fusible safety valve is required by code. Conforming to NFPA 31, this valve is listed under cULus MH 46634 and UL 842 for both the United States and Canada. It is approved for use with kerosene, No. 1 and No. 2 fuel oil per ASTM D396, B6 through B20 biodiesel blends per ASTM D396, and diesel fuel per ASTM D975. An embossed arrow on the valve body indicates the correct direction of oil flow, helping installers orient the valve correctly at rough-in.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic fusible link closure shuts off oil supply in the event of a fire, reducing fire damage\u003c\/li\u003e\n  \u003cli\u003eHigh-quality brass construction for durability and corrosion resistance in fuel oil service\u003c\/li\u003e\n  \u003cli\u003eDouble seal washer and o-ring system with Viton-equivalent materials rated for fuel oil and kerosene\u003c\/li\u003e\n  \u003cli\u003eManual handwheel functions as a service valve for routine oil burner maintenance\u003c\/li\u003e\n  \u003cli\u003eEmbossed flow-direction arrow aids correct installation orientation\u003c\/li\u003e\n  \u003cli\u003eListed under UL 842 for use in the US and Canada; conforms to cULus MH 46634 and NFPA 31\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eApproved for kerosene, No. 1 and No. 2 fuel oil per ASTM D396, B6 through B20 biodiesel blends per ASTM D396, and diesel fuel per ASTM D975.

Shut off the oil supply and depressurize the line before removing any existing valve or fittings. Ensure the embossed flow-direction arrow on the valve body points toward the burner, not the tank. Do not over-tighten flare or MPT connections; use appropriate thread sealant rated for fuel oil service on the MPT threads only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/2 inch MPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: 3\/8 inch OD Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Rating\u003c\/strong\u003e: 10 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Viton-equivalent double seal washer and o-ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosing Temperature Options\u003c\/strong\u003e: 165 degrees F or 200 degrees F depending on model\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Approvals\u003c\/strong\u003e: Kerosene, No. 1 and No. 2 fuel oil (ASTM D396), B6-B20 biodiesel (ASTM D396), diesel fuel (ASTM D975)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListings and Certifications\u003c\/strong\u003e: cULus MH 46634, UL 842 (US and Canada), NFPA 31\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: RW BECKETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RW BECKETT","offers":[{"title":"Default Title","offer_id":51467404247346,"sku":"12620","price":75.84,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946804.jpg?v=1783903632","url":"https:\/\/voomisupply.com\/products\/rw-beckett-12620-fusible-link-tank-valve-1-2-in-mpt-x-3-8-in-flare","provider":"Voomi Supply","version":"1.0","type":"link"}
