The bronze body construction provides durability in demanding commercial and industrial environments. With a 300 psi pressure rating at a 150 lb pressure class and solder end connections, this valve integrates directly into copper piping without threaded fittings. The PTFE seat material ensures a reliable, low-friction seal. An integral seat design simplifies installation and reduces potential leak points. This valve is domestically manufactured and carries a 5-year limited warranty.\u003c\/p\u003e\u003cp\u003eThe NJ7K006 is rated for commercial, mechanical, and industrial applications where backflow prevention is required in horizontal swing-check configurations. The Y-pattern body orientation makes it well suited for piping layouts where pressure drop must be minimized while maintaining reliable check performance. The 1\/2-inch nominal solder connection is compatible with standard copper tubing used throughout commercial mechanical systems. Note that this valve is not approved for potable drinking water service per CA Section 116875 and does not meet low-lead compliance requirements — it should not be installed in domestic water supply lines intended for human consumption.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eY-pattern swing check design minimizes pressure drop across the valve\u003c\/li\u003e\n\u003cli\u003eBronze body for corrosion resistance in commercial and industrial service\u003c\/li\u003e\n\u003cli\u003ePTFE seat material provides a reliable, low-friction sealing surface\u003c\/li\u003e\n\u003cli\u003eIntegral seat construction reduces assembly complexity and leak paths\u003c\/li\u003e\n\u003cli\u003eSolder end connections for direct copper pipe installation\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured with a 5-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for commercial, mechanical, and industrial piping systems using 1\/2-inch nominal copper tubing with solder connections.

Shut off and depressurize the system completely before soldering the valve into the line. Follow standard copper sweat-solder procedures, ensuring the valve body does not overheat during the soldering process, as excessive heat can damage internal components. Verify correct flow direction by confirming the arrow on the valve body aligns with intended flow before completing the installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S-433-Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/2 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Solder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: PTFE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop to Inlet Center\u003c\/strong\u003e: 1.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Commercial, Mechanical and Industrial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Lead Compliance\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5 Years Limited\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: NJ7K006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51620033986866,"sku":"39923636225","price":106.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f9ab276268f73ce9f2b3663dd4b1ee1_3956dd0d-86f3-4e44-acfb-860781e70472.jpg?v=1787339368","url":"https:\/\/voomisupply.com\/products\/nibco-nj7k006-s-433-y-swing-check-valve-1-2-in-solder","provider":"Voomi Supply","version":"1.0","type":"link"}
