The valve features a double union design for easy in-line removal without disturbing adjacent piping, and uses an elastomer disc for reliable sealing performance. It accepts maximum inlet pressure up to 400 psi and delivers an adjustable outlet pressure range of 25 to 75 psi. The 3\/4-inch female NPT threaded connections make this valve compatible with standard threaded pipe assemblies. Licensed plumbers and pipefitters typically install this valve as part of a service entrance or branch line pressure management strategy.\u003c\/p\u003e\u003cp\u003eThis valve is suited for residential and light commercial plumbing installations where incoming supply pressure must be reduced to safe working levels for downstream fixtures and appliances. The double union configuration is particularly useful in retrofit and service scenarios where the valve may need to be removed for inspection or replacement without cutting pipe. The lead-free construction meets regulatory requirements for potable water applications, making it appropriate for use in jurisdictions that mandate lead-free plumbing components in drinking water systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free construction meets potable water regulatory requirements\u003c\/li\u003e\n\u003cli\u003eDouble union body design allows in-line removal without pipe cutting\u003c\/li\u003e\n\u003cli\u003eAdjustable outlet pressure range of 25 to 75 psi\u003c\/li\u003e\n\u003cli\u003eRated for maximum inlet pressure of 400 psi\u003c\/li\u003e\n\u003cli\u003eElastomer disc provides durable, reliable sealing\u003c\/li\u003e\n\u003cli\u003e3\/4-inch female NPT threaded connections for standard pipe compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure reducing valve for 3\/4-inch NPT threaded potable water supply systems in residential and light commercial plumbing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and relieve system pressure completely before removing or installing this valve. The double union connections allow for straightforward in-line servicing, but ensure all union nuts are hand-tight before applying wrench torque to avoid thread damage. After installation, gradually restore water pressure and verify the outlet pressure setting with a gauge before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Female NPT Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Design\u003c\/strong\u003e: Double Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Material\u003c\/strong\u003e: Elastomer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inlet Pressure\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Outlet Pressure\u003c\/strong\u003e: 25 to 75 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 26.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS BRASS TUBULAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3\/4 LFN45BM1-DU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51525479137586,"sku":"3\/4 LFN45BM1-DU","price":1177.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d293d423705caa63e944860cc53f46b1.jpg?v=1785475038","url":"https:\/\/voomisupply.com\/products\/watts-brass-tubular-3-4-lfn45bm1-du-pressure-reducing-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
