Built with a bronze body and a nitrile butadiene rubber (NBR) seal, it handles working pressures up to 200 psi (WOG rating). The Y-pattern configuration reduces flow restriction compared to swing-style check valves, making it well-suited for applications where pressure drop is a concern. Both end connections are female NPT (FNPT x FNPT) for straightforward threaded installation. Sized at 2 inches, this valve is installed by licensed plumbers and pipefitters in commercial and industrial piping systems.\u003c\/p\u003e\n\u003cp\u003eThis check valve is appropriate for use in water, oil, and gas service within the rated pressure limits. The Y-pattern body design positions the internal disc at an angle to the flow path, which supports smoother flow characteristics and easier inline servicing compared to other check valve configurations. It is a common choice for mechanical rooms, boiler systems, pump discharge lines, and general process piping where backflow prevention is required. The FNPT x FNPT end connections make it compatible with standard threaded pipe installations without the need for special fittings or adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eY-pattern body design reduces pressure drop and supports smooth, low-turbulence flow\u003c\/li\u003e\n  \u003cli\u003eBronze body construction provides corrosion resistance in water and compatible fluid service\u003c\/li\u003e\n  \u003cli\u003eNitrile butadiene rubber (NBR) seal offers durability across a broad range of fluid types\u003c\/li\u003e\n  \u003cli\u003e200 psi WOG maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for standard threaded pipe installations\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2008 quality management standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 2-inch threaded piping systems handling water, oil, or gas service within the 200 psi WOG pressure rating. Verify fluid compatibility with the NBR seal material before installation in chemical or solvent service.\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 local plumbing codes and IPC guidelines. Depressurize and drain the system completely before removing any existing valve or fitting. Apply thread sealant or PTFE tape to male threads before making up the FNPT connections, and tighten to the torque appropriate for bronze-to-pipe thread joints per shop practice. Verify flow direction marked on the valve body before final assembly, as reversing a check valve renders it non-functional.\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 psi WOG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.842 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008\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: NL7500D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51542703276338,"sku":"NL7500D","price":627.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a07ec0e1997c37ac34dffa2dc55e204e_945b4b94-0efa-4072-96e2-ce87faae1eb0.jpg?v=1785904798","url":"https:\/\/voomisupply.com\/products\/nibco-nl7500d-check-valve-2-in-y-pattern-fnpt-200-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
