    Circuit Balancing Valve - Ductile Iron, Fixed Orifice, Flanged
    NIBCO makes it faster and easier to accurately balance HVAC and mechanical hot and chilled water systems. Our F739 Series Ductile Iron fixed orifice manual balancing valve is faster and easier to set because it does not require any special calculators or meters to set. integral pressure temperature ports provide a direct readout across the orifice; optimum flow is quickly and accurately determined by simply measuring the differential pressure. NIBCO's fixed orifice flanged end manual balancing valve also provides a isolation function for system maintenance. The integral memory stop feature allows the system to be returned to its retained settings once maintenance is complete.
