FlowCon Wafer The High Flow Valve Series Dynamic Flow Limiters The FlowCon Wafers maintain correct flow despite pressure changes within the given ΔP range (or the narrow common range when looking at multiple in- serts with different ranges). Size: DN50-1000 (2”-40”) ΔP ranges: 10-880 kPaD / 1-128 psid (divided over 7 spans) Flow range: 0.883-2287 l/sec / 14-36250 GPM Media temperature: DN50-80 (2”-3”): -20°C to +135°C / -4°C to +275°F DN100+ (4”-40”): -20°C to +175°C / -4°C to +347°F Static Pressure: DN50-80 (2”-3”): 2500 kPa / 360 psi DN100+ (4”-40”): 3400 kPa / 493 psi. Housings The FlowCon Wafer housing is ductile iron and for double flange connection. Applications Proper flow rate to a cooling tower is essential for adequate removal of heat from the condenser section of a chiller. Use of dynamic valves main- tains even distribution to each condenser and prevents cooling tower flooding. Chillers are often designed in parallel to allow equipment staging. This allows chillers to come online only when required during peak cooling hours. A FlowCon Wafer on each chiller prevents excess flow caused by over pumping during light load conditions and it assures flow rate to be within required range of the equipment. In systems with pumps in parallel, the FlowCon Wafer is essential as the slightest difference in pump characteristics will result in pump overload and system inefficiency. Dissimilar or different sized pumps accentuate this problem. Installation Hydronic function of a FlowCon Wafer is not affected whether it is installed in the supply- or returnpipe and the valves may also be installed either horizontally or vertically.
