Constructed from cast iron, this valve carries a 125 psi working steam pressure (WSP) rating and a maximum working pressure of 200 psi, making it suitable for demanding service environments. It meets MSS SP-71 standards and is rated for temperatures up to 450 degrees F. Licensed plumbers and pipefitters install this type of valve as part of larger distribution or process piping systems where reverse flow must be controlled.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for inline installation in commercial plumbing, hydronic heating, process piping, and industrial fluid-handling systems. The flanged end connection simplifies bolt-up installation to mating flanged pipe or equipment. At 82 pounds, this is a heavy-duty component intended for permanent installation in 4-inch piping runs. It is not a residential-grade fitting — the size and weight class place it firmly in light commercial to industrial applications typically handled by journeyman or master plumbers and pipefitters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast iron body for durability in commercial and industrial service\u003c\/li\u003e\n  \u003cli\u003eFlanged end connections for straightforward bolt-up installation\u003c\/li\u003e\n  \u003cli\u003e125 psi WSP rating with a 200 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated for temperatures up to 450 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets MSS SP-71 standard for cast iron swing check valves\u003c\/li\u003e\n  \u003cli\u003eInline configuration prevents backflow in pressurized piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flanged swing check valve for 4-inch pipe installations in commercial and industrial piping systems meeting MSS SP-71 requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Shut down and fully depressurize the piping system before beginning work, and verify that all fluid has been drained from the line. Flanged connections require matching flange faces, appropriate gaskets, and properly torqued fasteners per the flange standard in use. Verify flow-direction arrow on the valve body is aligned with intended flow before bolting up.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Inline Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWSP Rating\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 450 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: MSS SP-71\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 82 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: 116-204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51540844871986,"sku":"116-204","price":640.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4d68dfbe60d3f1ae54939bce95d1a2e_534073f1-82d5-4798-9052-fcedd171d961.jpg?v=1785864829","url":"https:\/\/voomisupply.com\/products\/legend-valve-116-204-flanged-check-valve-4-inch-125-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
