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. The F739 series ductile iron fixed orifice manual balancing valve is complete with integral pressure temperature ports and memory stop. Direct system readings are taken across the orifice. Depending on size, the F739 series provides between 2880 - 6480 degrees of throttling adjustment, resulting in precise setting of system flow. The Nibco manual balancing valves provide the ultimate solution for a wide range of mechanical and HVAC chilled and hot water application requirements to ensure a balanced system and a comfortable indoor climate. Nibco valves and components are also backed by the Nibco 5-years 125% limited warranty.
