Built with a lead free copper silicon alloy body and a bronze sealed spring cage, it is suited for accessible outdoor waterworks or pit installations where corrosion resistance and durability are required. The valve adjusts outlet pressure from 25 to 75 psi, with a factory standard setting of 50 psi, and can handle incoming supply pressure up to 400 psi. An integral stainless steel strainer and thermal expansion bypass are built in, reducing the need for additional inline components.\u003c\/p\u003e\u003cp\u003eThis PRV fits into commercial and residential cold and hot water supply lines where incoming municipal or well pressure exceeds safe operating limits for downstream fixtures, appliances, and plumbing components. The solder union inlet and outlet connections make it appropriate for copper pipe systems. Its operating temperature range of 33 to 180 degrees F makes it suitable for both cold water service and domestic hot water applications. Licensed plumbers install this valve as part of new construction, remodel, or system upgrade projects requiring pressure management and water conservation compliance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead free copper silicon alloy body meets lead free installation requirements for potable water systems\u003c\/li\u003e\n\u003cli\u003eAdjustable pressure range of 25 to 75 psi with a standard factory setting of 50 psi\u003c\/li\u003e\n\u003cli\u003eRated for maximum working pressure of 400 psi on the inlet side\u003c\/li\u003e\n\u003cli\u003eIntegral stainless steel strainer protects the valve seat from debris without a separate inline filter\u003c\/li\u003e\n\u003cli\u003eThermal expansion bypass built in to handle pressure fluctuations caused by water heater expansion\u003c\/li\u003e\n\u003cli\u003eBronze sealed spring cage designed for pit or outdoor waterworks installations\u003c\/li\u003e\n\u003cli\u003eSolder union inlet and outlet connections for copper pipe integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation PRV for 1-inch copper pipe residential and commercial plumbing systems requiring pressure reduction on potable water supply lines.\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 any existing valve or making new connections. The solder union connections require standard copper soldering tools and flux rated for potable water service. After installation, adjust outlet pressure with the system charged and verify the setting with a calibrated pressure gauge downstream of the valve.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection Type\u003c\/strong\u003e: Union Joint (Solder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection Type\u003c\/strong\u003e: Union Joint (Solder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Reduced Pressure Range\u003c\/strong\u003e: 25 to 75 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Reduced Pressure Setting\u003c\/strong\u003e: 50 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 33 to 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Lead Free Copper Silicon Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Material\u003c\/strong\u003e: Reinforced EPDM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrainer Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegral Strainer\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Expansion Bypass\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: LFN55B-M1\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: lfn55bm1-du-s 1\"\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51268349428018,"sku":"LFN55BM1-DU-S 1\"","price":264.01,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/watts-lfn55bm1-du-s-1-inches-pressure-reducing-valve-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
