Built with a cast iron body and a bolted bonnet, this valve is engineered for reliable full-bore shutoff in commercial and industrial piping systems. The solid wedge disc provides positive sealing across the full flow path. Rated at pressure class 125, it is a standard choice for steam, water, and other compatible fluid services where a robust, field-serviceable gate valve is required. A wheel handle allows for manual operation without additional tooling.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for commercial mechanical rooms, industrial process piping, and building utility systems where flanged connections and OS and Y visibility requirements apply. The OS and Y stem design makes it easy to confirm open or closed position at a glance, which is a common requirement for fire protection and insurance compliance in commercial installations. Licensed plumbers, pipefitters, and mechanical contractors typically specify this valve in larger-diameter system applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOS and Y stem design allows visible indication of valve position (open or closed)\u003c\/li\u003e\n  \u003cli\u003eSolid wedge disc delivers positive, full-bore shutoff with minimal flow restriction\u003c\/li\u003e\n  \u003cli\u003eBolted bonnet construction simplifies field inspection and repacking\u003c\/li\u003e\n  \u003cli\u003eCast iron body rated at pressure class 125 for broad compatibility with commercial piping systems\u003c\/li\u003e\n  \u003cli\u003eFlanged end connection for secure, removable installation in 3-inch pipe systems\u003c\/li\u003e\n  \u003cli\u003eWheel handle allows manual operation without specialized tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation gate valve for 3-inch flanged piping systems operating within pressure class 125 ratings, typical in commercial HVAC, plumbing, and industrial fluid service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical and plumbing codes, including ASME and local jurisdictional requirements. Depressurize and drain the piping system fully before removing or installing any flanged valve. Verify flange bolt pattern and gasket compatibility before installation. The OS and Y configuration requires clearance above the valve for full stem travel when the valve is opened.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: OS and Y Gate Valve with Iron Trim\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Style\u003c\/strong\u003e: Solid Wedge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBonnet Style\u003c\/strong\u003e: Bolted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Wheel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 66 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: NIBCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NHA3LJF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51541523169586,"sku":"NHA3LJF","price":1044.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9a0f243ee91ec7654b5cc8f3b83f798.jpg?v=1785878249","url":"https:\/\/voomisupply.com\/products\/nibco-nha3ljf-gate-valve-3-inch-flanged-cast-iron-125","provider":"Voomi Supply","version":"1.0","type":"link"}
