The rising stem and yoke design gives visual confirmation of the open or closed position without needing to check downstream pressure, which is a critical feature in life-safety applications. Rated to 300 psi, this 8-inch valve is sized for large-diameter mains where reliable shutoff is essential. It is installed by licensed fire protection contractors, mechanical contractors, and licensed plumbers working on fire suppression headers, standpipe systems, and similar high-pressure water distribution lines.\u003c\/p\u003e\n\u003cp\u003eThis valve is intended for use as a main control or sectional shutoff valve on wet-pipe and dry-pipe fire sprinkler systems, standpipe risers, and industrial water mains. The flanged end connections allow direct bolt-up to standard pipe flanges, making it suitable for both new construction and retrofit installations where a full-bore, low-restriction gate valve is required. ULC and FM listings confirm it meets fire protection authority standards for use in listed fire suppression assemblies in the United States and Canada.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOutside screw and yoke (OSY) rising stem provides immediate visual open-or-closed status indication\u003c\/li\u003e\n  \u003cli\u003e300 psi pressure rating suitable for high-demand fire protection and industrial water systems\u003c\/li\u003e\n  \u003cli\u003e8-inch flanged end connections for direct bolt-up to standard pipe flanges\u003c\/li\u003e\n  \u003cli\u003eULC listed and FM approved for use in certified fire suppression system assemblies\u003c\/li\u003e\n  \u003cli\u003eFull-bore gate design minimizes flow restriction in large-diameter mains\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flanged OSY gate valve for 8-inch fire protection mains and industrial water supply headers requiring ULC and FM listed components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed fire protection or mechanical contractor in accordance with NFPA 13, NFPA 14, and applicable local codes. Depressurize and isolate the system section before installation, and verify flange bolt pattern and gasket compatibility with the mating pipe flanges prior to assembly. Supervisory switches are commonly installed on OSY valves in fire suppression systems to provide tamper monitoring through the fire alarm panel. Do not use this valve to throttle flow; gate valves are designed for full-open or full-closed service only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Outside Screw and Yoke (OSY) Gate Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListings and Approvals\u003c\/strong\u003e: ULC Listed, FM Approved\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: ANVIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AOSY3-FF-080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ANVIL","offers":[{"title":"Default Title","offer_id":51468222038322,"sku":"AOSY3-FF-080","price":1790.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947061.jpg?v=1783914925","url":"https:\/\/voomisupply.com\/products\/anvil-aosy3-ff-080-osy-flanged-gate-valve-8-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
