• Balancing Valve - Manual, Lead Free Brass, FPT Body x Sweat Tailpiece, Stainless Steel Ball and Stem, ST-1805-66


    Balancing Valve - Manual, Lead Free Brass, FPT Body x Sweat Tailpiece, Stainless Steel Ball and Stem
    NIBCO makes it easy to balance mechanical and plumbing systems with our new lead-free and dezincification-resistant manual balancing valve. Our lead-free 1805 Series fixed orifice manual balancing valve is faster and easier to set because it does not require any special calculators or meters. Integral pressure temperature ports provide a direct readout across the orifice; optimum flow is quickly and accurately determined by simply measuring the differential pressure. The NIBCO® 1805 manual balancing valves are equipped with a union end that will provide up to a double reduction in inlet connection size. A isolation feature and a memory stop is also provided for system maintenance. The integral memory stop will return the system its origional setting upon completion.
