Part of the FLO-BOSS 1810 Series, this valve features integral pressure-temperature (PT) ports that allow direct system readings across the orifice without special calculators or additional metering equipment. The valve delivers 1440 degrees of throttling adjustment for precise flow control. An integral memory stop allows the valve to be isolated for maintenance and returned to its pre-set flow position once service is complete. Dezincification-resistant construction supports long service life in aggressive water conditions.\u003c\/p\u003e\u003cp\u003eThe S-1810-LF-2 is suited for commercial and residential hydronic heating and cooling systems, domestic hot water recirculation, and plumbing distribution applications requiring balanced flow across multiple circuits. The 2-inch solder-end configuration makes it appropriate for copper piping installations in mechanical rooms, terminal unit branches, and riser assemblies. It is installed by licensed plumbers and mechanical contractors working on balanced-loop systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFixed orifice with integral PT ports for direct differential pressure readings across the valve\u003c\/li\u003e\n\u003cli\u003e1440 degrees of throttling adjustment for precise flow-rate setting\u003c\/li\u003e\n\u003cli\u003eIntegral memory stop allows system isolation and return to retained settings after maintenance\u003c\/li\u003e\n\u003cli\u003eLead-free and dezincification-resistant construction\u003c\/li\u003e\n\u003cli\u003eSolder-end (sweat) connection for copper pipe installation\u003c\/li\u003e\n\u003cli\u003eBacked by the NIBCO 5-year 125% limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style fixed-orifice manual balancing valve for 2-inch copper pipe hydronic and plumbing systems requiring lead-free components.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or mechanical contractor in accordance with applicable IPC and local plumbing codes. Shut down and depressurize the system before soldering the valve into the line. Avoid applying excessive heat to the valve body during soldering to protect internal components. After installation, use the PT ports and a calibrated differential pressure meter to verify flow balance across the circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Solder End (Sweat)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Type\u003c\/strong\u003e: Fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrottling Range\u003c\/strong\u003e: 1440 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDezincification-Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegral PT Ports\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMemory Stop\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5-year 125% limited\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 039923368508\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: S-1810-LF-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51383229284658,"sku":"S-1810-LF-2","price":408.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673252.png?v=1782590390","url":"https:\/\/voomisupply.com\/products\/nibco-s-1810-lf-2-manual-balancing-valve-2-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
