2" Brass Ball Valve Threaded - Lead Free (947-LF)

The 2" Lead Free Brass Ball Valve (947-LF) is a full port, quarter-turn shut-off valve built for commercial plumbing systems, irrigation pump stations, industrial process piping, and mechanical systems where code-compliant lead-free construction, 600 WOG pressure performance, and reliable on/off isolation are required at the 2" pipe size. At 2", lead-free brass ball valves are firmly in commercial and light industrial service territory — this is not a residential fixture valve but a primary system shut-off, a pump station isolation valve, an equipment supply and return service valve, and a mainline isolation point for commercial irrigation systems, HVAC primary distribution connections, industrial process water headers, and water treatment plant branch piping where threaded installation is standard and the specification requirements demand a listed, rated, and certified valve at every isolation point. The lead-free brass body satisfies NSF 372 and Safe Drinking Water Act compliance requirements, making this valve fully approved for potable water service and code-compliant in all U.S. jurisdictions where lead-free materials are mandated on drinking water systems — a non-negotiable requirement at 2" where commercial potable water systems are inspected, permitted, and formally documented at every isolation valve location.

The 2" size is the largest size in the standard lead-free brass NPT ball valve series, and at this diameter the valve carries the full 600 WOG cold working pressure rating of the series alongside the robust commercial construction that makes brass ball valves the default isolation valve specification across commercial plumbing, irrigation, and mechanical systems at this service size. Female NPT connections on both ends thread directly onto standard 2" NPT pipe or fittings with pipe tape or thread sealant for a fast, leak-free, permanent connection without special tools, solvents, or press equipment — the most widely used connection method for commercial system isolation valves at this size across the plumbing, irrigation, and mechanical trades. The 2" body is sized and weighted for the demands of commercial service — heavier construction than the smaller sizes in the series, with handle torque and lever sizing matched to the larger ball and seat dimensions required for reliable quarter-turn operation at 2" under full commercial system pressure conditions.

The full port ball design maintains an unobstructed flow path equal to the pipe's full interior bore when open — zero restriction, zero turbulence, and no measurable pressure drop across the valve. At the 2" size on commercial pump discharge connections, irrigation primary mains, and HVAC primary distribution headers, this full port performance is operationally significant: partial-port valves at 2" introduce backpressure and flow restriction that directly affects pump operating efficiency, system flow rates, and downstream pressure on every connected zone and piece of equipment. The chrome-plated brass ball rotates against PTFE seats for a smooth, low-torque quarter-turn operation and a reliable bubble-tight shut-off that holds up through years of commercial service, repeated cycling, and the water quality and pressure conditions of commercial systems where valve reliability directly affects operational uptime.

The steel lever handle delivers fast, unambiguous quarter-turn actuation with an immediate visual read on valve position — parallel to the pipe is open, perpendicular is closed — a critical feature on commercial systems where valve position confirmation is part of normal operations and maintenance procedures. Rated at 600 WOG, the 947-LF handles the pressure demands of every commercial and light industrial application at 2" with a substantial safety margin, and the blowout-proof stem provides an additional layer of safety under the sustained line pressures of commercial system service.

Industries & Applications:

• Commercial Plumbing — Primary System Isolation — At 2", lead-free brass NPT ball valves are the standard primary shut-off specification on commercial building water service entries, main distribution headers, equipment room isolation points, and riser connections in office buildings, hotels, multifamily housing, schools, and healthcare facilities where 2" is the primary distribution main size and every isolation valve must carry NSF 372 lead-free listing and be rated and certified for the system's operating pressure and potable water service requirements
• Irrigation & Landscape — Pump Station Isolation — The 2" size is the most common pump station discharge connection and primary main isolation valve size on commercial irrigation systems at golf courses, sports complexes, parks, commercial farms, and municipal landscape installations; the 947-LF provides a full port, 600 WOG rated, lead-free brass isolation point at the pump discharge connection, mainline shut-off, and zone manifold supply header where a reliable, commercially rated threaded ball valve is the correct specification for primary system isolation at this service size
• HVAC & Mechanical Systems — Used on 2" chilled water primary distribution connections, condenser water supply and return shut-offs, primary hydronic heating and cooling isolation points, and equipment room service valves in commercial and light industrial mechanical systems where 2" is the primary distribution connection size; brass ball valve construction withstands the pressure cycling, water treatment chemistry, and temperature variations of commercial HVAC system service, and the 600 WOG rating provides a substantial safety margin above commercial mechanical system operating pressures at this primary distribution connection size
• Industrial Process Piping — Installed on 2" process water mains, cooling water primary headers, plant utility isolation points, and pump discharge connections in manufacturing, chemical processing, and light industrial facilities where Schedule 40 or Schedule 80 PVC systems transition to brass at isolation valve locations, or where all-brass system construction at the 2" primary header level calls for a rated, certified isolation valve at every isolation and service point
• Municipal Water & Water Treatment — NSF 61 & 372 certified for potable water contact; appropriate for 2" isolation valve applications in water treatment plant branch distribution, chemical feed line shut-offs, pump station primary headers, and distribution system service connections where lead-free, listed materials are required at every valve and the 600 WOG pressure rating satisfies the system's operating and safety margin requirements
• Commercial Well Systems & Booster Stations — Used on 2" commercial well pump discharge connections, booster pump station supply and discharge isolation, and primary well system distribution headers where a commercially rated, lead-free brass ball valve is the correct threaded isolation valve specification at the primary system connection size; the 600 WOG rating accommodates commercial pump shut-off head and surge pressure conditions at the 2" service size with a substantial safety margin
• Pool & Spa — Commercial Equipment Pads — Brass construction withstands the humid, chemically active environment around commercial pool pump rooms, filter equipment, heaters, and salt chlorine generators; used on 2" equipment supply and return connections, primary recirculation system isolation points, and pump station supply shut-offs at commercial pools and aquatic centers where 2" is the primary equipment connection size and a rated, lead-free brass ball valve is the correct isolation valve specification at the equipment pad level
• Fire Suppression Support Systems — Used on 2" auxiliary water supply connections, test and drain line isolation points, and primary system support connections adjacent to wet sprinkler and standpipe systems where a rated, corrosion-resistant, threaded isolation valve is required at the 2" primary connection size; verify applicable fire suppression system code requirements before specifying for direct fire suppression service
