It allows flow in one direction and closes automatically to prevent backflow, protecting pumps, compressors, and piping systems from reverse-flow damage. The bronze body handles a maximum working pressure of 600 WOG (water, oil, gas) and is rated to 421 degrees F, making it suitable for a wide range of commercial and industrial plumbing applications. The PTFE seal material provides reliable seating and chemical resistance. Licensed plumbers and pipefitters are the primary installers of this valve in both new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThe NL9200C fits 1-1\/2 inch female NPT threaded connections on both the inlet and outlet sides, making it a straightforward drop-in for standard threaded piping systems. The Y-pattern body design reduces turbulence and pressure drop across the valve compared to inline swing check designs. Typical installations include domestic water supply, hydronic heating loops, compressed air lines, and light oil service where backflow prevention and pressure retention up to 600 psi are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBronze body construction for corrosion resistance in water, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eY-pattern design reduces flow restriction and pressure drop\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for standard threaded pipe installation\u003c\/li\u003e\n  \u003cli\u003e600 WOG maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003ePTFE seal material for chemical resistance and reliable shutoff\u003c\/li\u003e\n  \u003cli\u003eRated to 421 degrees F maximum operating temperature\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 FNPT threaded piping systems in commercial and residential plumbing, hydronic, and light industrial 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 codes and the IPC. Shut off the water or fluid supply and fully depressurize the line before removing or installing any valve. Apply thread sealant or PTFE tape to the male threads of the mating pipe before assembly, and do not over-tighten bronze-body fittings. Confirm the flow-direction arrow on the valve body matches the intended flow direction before completing the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Y-Pattern Check Valve\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\u003eSeal Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 600 psi WOG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 421 degrees F (216 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.842 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: NL9200C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51541819752754,"sku":"NL9200C","price":604.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2088a0bae7b60455a15cd4a7527e25c.jpg?v=1785885828","url":"https:\/\/voomisupply.com\/products\/nibco-nl9200c-check-valve-1-1-2-in-y-pattern-fnpt-600-wog","provider":"Voomi Supply","version":"1.0","type":"link"}
