It fills the boiler and piping system with water, maintains system pressure at all times, and supplies make-up water in the event of system leaks. The body is constructed of bronze with a union threaded inlet and NPT threaded outlet. Internal components include a tight seating check valve and a stainless steel strainer. A purge lever allows for manual system purging without additional tools. Maximum working pressure is 100 psi. The simplified servicing design reduces downtime during maintenance calls.\u003c\/p\u003e\n\u003cp\u003eThis regulator is suited for installation on boiler feed lines in both residential and light commercial hydronic heating systems. The 1\/2 inch IPS union inlet connection allows for straightforward inline installation and removal without disturbing adjacent piping. The high capacity flow design makes it appropriate for systems with greater water volume demands. Licensed plumbers and HVAC technicians are the typical installers in new construction and retrofit applications alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh capacity flow performance for demanding hydronic heating system applications\u003c\/li\u003e\n  \u003cli\u003eBronze body construction for durability in potable and heating system water service\u003c\/li\u003e\n  \u003cli\u003eUnion threaded inlet connection simplifies removal and servicing without cutting pipe\u003c\/li\u003e\n  \u003cli\u003eTight seating check valve prevents backflow within the feed line\u003c\/li\u003e\n  \u003cli\u003eStainless steel strainer protects internal components from debris\u003c\/li\u003e\n  \u003cli\u003eManual purge lever enables on-demand system purging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation feed water pressure regulator for residential and commercial hydronic heating and boiler systems with 1\/2 inch IPS inlet connections and NPT outlet connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician in accordance with local plumbing codes and the IFGC where applicable. Shut off the water supply and depressurize the system completely before removing or installing this regulator. Use appropriate pipe thread sealant on NPT connections and verify all union fittings are hand-tight before final torque with a wrench. After installation, cycle the system and check all connections for leaks before returning the boiler to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/2 inch IPS union threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: 1\/2 inch NPT threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 100 psi (6.9 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrainer Material\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCheck Valve\u003c\/strong\u003e: Tight seating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePurge Lever\u003c\/strong\u003e: Included\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: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 386421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51468252512562,"sku":"386421","price":141.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946499.jpg?v=1783915968","url":"https:\/\/voomisupply.com\/products\/watts-386421-feed-water-pressure-regulator-100-psi-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
