It allows technicians to isolate a circulator pump from the system without draining the piping, simplifying pump service and replacement. The rotating flange design makes alignment easier during installation. This valve is lead free, meeting potable water and plumbing code requirements where applicable. It is a practical, code-compliant component for residential and light commercial hydronic systems.\u003c\/p\u003e\u003cp\u003eThis valve is used in closed-loop hydronic systems where circulator pump isolation is required. The threaded connection suits standard pipe installations, and the rotating flange accommodates various pump flange orientations. Plumbers and HVAC technicians installing or servicing hot water heating systems, chilled water loops, or domestic recirculation systems will find this valve suited to those applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch threaded connection for standard pipe compatibility\u003c\/li\u003e\n\u003cli\u003eRotating flange design simplifies pump alignment during installation or replacement\u003c\/li\u003e\n\u003cli\u003eLead free construction for compliance with applicable potable water codes\u003c\/li\u003e\n\u003cli\u003eIsolation function allows pump service without full system drain-down\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pump isolation valve for 1-inch threaded circulator pump applications in residential and light commercial hydronic systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and allow the system to cool before beginning any pump or valve work. Follow applicable local plumbing codes and IFGC requirements when installing in hydronic heating systems. Use thread sealant rated for the system fluid and operating temperature on all threaded connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded with rotating flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\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: h-41404whv\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51233486537010,"sku":"H-41404WHV","price":94.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633367.jpg?v=1780101151","url":"https:\/\/voomisupply.com\/products\/nibco-h-41404whv-1-inch-pump-isolation-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
