Built with a bronze body and Viton seal, it handles working pressures up to 200 psi (WOG) and temperatures up to 353 degrees F. The 1\/4 inch FNPT x FNPT end connections make it straightforward to thread into existing pipelines. Plumbers and pipefitters install this valve in commercial and industrial plumbing, HVAC hydronic circuits, and light industrial fluid systems where backflow prevention is required on smaller-diameter lines.\u003c\/p\u003e\n\u003cp\u003eThe NL740V4 is suited for residential and light commercial applications where a compact, reliable check valve is needed on a 1\/4 inch line. The Y-pattern body design provides lower pressure drop compared to swing-type configurations, making it practical in systems where flow efficiency matters. FNPT x FNPT connections allow direct inline installation without additional fittings in most threaded piping assemblies. This valve is appropriate for water, oil, and gas service within its rated pressure and temperature limits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eY-pattern body design for reduced inline pressure drop\u003c\/li\u003e\n  \u003cli\u003eBronze body construction for corrosion resistance in plumbing and HVAC applications\u003c\/li\u003e\n  \u003cli\u003eViton seal material provides compatibility with a range of fluid media and elevated temperatures\u003c\/li\u003e\n  \u003cli\u003e200 psi WOG (Water, Oil, Gas) working pressure rating\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch FNPT x FNPT connections for direct threaded inline installation\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2008 quality standards\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\/4 inch threaded piping systems in plumbing, hydronic, and light industrial applications.\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 the IPC. Shut off system pressure and drain the line before removing or installing any inline valve. Apply appropriate thread sealant to FNPT connections and avoid over-tightening, which can crack bronze fittings. Verify flow direction arrow on the valve body aligns with intended flow direction before completing 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\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\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\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Viton\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: 353 degrees F (178 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.509 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: NL740V4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51540536885554,"sku":"NL740V4","price":159.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9219a23a4e0675c8c5f52efa02e5fdb.jpg?v=1785857807","url":"https:\/\/voomisupply.com\/products\/nibco-nl740v4-y-pattern-check-valve-1-4-inch-fnpt-bronze","provider":"Voomi Supply","version":"1.0","type":"link"}
