Built with a bronze body and FNPT x FNPT end connections, it is suited for installations where a low-profile, inline check valve is required. The Y-pattern body configuration provides reduced turbulence and pressure drop compared to swing-style designs. At 1-1\/2 inches pipe size, it fits standard residential and light commercial piping. Licensed plumbers and pipefitters are the typical installers for this type of valve.\u003c\/p\u003e\n\u003cp\u003eThis check valve is appropriate for use in domestic water supply, hydronic heating, and general plumbing distribution systems. The FNPT x FNPT connection type makes it compatible with standard threaded pipe installations, simplifying integration into existing systems. It is commonly used in mechanical rooms, boiler rooms, and utility piping where backflow prevention is required without the need for a dedicated bypass or external actuator.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eY-pattern body design reduces flow turbulence and inline pressure drop\u003c\/li\u003e\n  \u003cli\u003eBronze body construction provides corrosion resistance in water service applications\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch pipe size suits residential and light commercial plumbing\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B1.20.1 and ANSI\/ASME B16.18 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for 1-1\/2 inch threaded piping systems in residential and light commercial plumbing and hydronic applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing any existing valve or fitting. Apply thread sealant or PTFE tape to male threads per standard practice before making up FNPT connections. Verify flow direction markings on the valve body before final assembly to ensure correct orientation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Y-Pattern Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\/ASME B1.20.1, ANSI\/ASME B16.18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.875 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: LEGEND VALVE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 105-307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51542531309874,"sku":"105-307","price":124.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d569bd501b32c1feb7f99d9ab2e613a6.jpg?v=1785902940","url":"https:\/\/voomisupply.com\/products\/legend-valve-105-307-y-pattern-check-valve-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
