Built to lead-free standards, this valve allows a technician to isolate a circulator pump or inline pump for service or replacement without draining the entire system. The rotating flange simplifies alignment during installation and reduces the effort required to mate the valve to a pump flange face. Licensed plumbers and hydronic system technicians are the primary installers of this valve type.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for closed-loop hydronic heating systems, domestic water recirculation loops, and similar pressurized piping applications where pump serviceability is a design requirement. The press-connection end eliminates the need for soldering or threaded fittings at the pipe connection point, making it a practical choice for retrofit and new construction installs where open-flame work is restricted or undesirable. It is intended for 2-inch nominal pipe size installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch press-connection end for flame-free installation on copper or compatible tubing\u003c\/li\u003e\n  \u003cli\u003eRotating flange allows angular adjustment for precise pump alignment\u003c\/li\u003e\n  \u003cli\u003eLead-free construction meets applicable potable water and plumbing code requirements\u003c\/li\u003e\n  \u003cli\u003ePump isolation design enables in-line pump removal without full system drain-down\u003c\/li\u003e\n  \u003cli\u003eFlange-style pump interface suits standard circulator and inline pump bolt patterns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation pump isolation valve for 2-inch press-fit piping systems in residential and light commercial hydronic and recirculation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified hydronic systems technician in accordance with local plumbing codes and IPC requirements. Depressurize and isolate the piping system before beginning work. Press connections require a calibrated press tool with the correct jaw size for the fitting diameter. Verify the rotating flange is properly aligned and fasteners are evenly torqued to the pump flange before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Press\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Rotating flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\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: h-81407whv\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51233285308722,"sku":"H-81407WHV","price":230.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629503.jpg?v=1780096254","url":"https:\/\/voomisupply.com\/products\/nibco-h-81407whv-2-in-press-pump-isolation-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
