HOW TO SELECT The FlowCon Partner Globe is to be selected based on the required design flow and pipe size. The FlowCon Partner Globe’s pressure loss ΔpBV is found in the flow/pressure/setting diagrams. Each size has its own associated valve diagram. After correct setting, the FlowCon Partner Globe will ensure flow never to exceed design flow + tolerances even at partial load conditions. EXAMPLE: Design flow = 50000 l/hr = 50 m3/hr (220 GPM) Pipe size = DN100 (4”) Select valve based on line size and system requirements to eliminate pipe modifications. In this example FlowCon Partner Globe DN100 (4”) is selected. With its maximum flow of 180 m3/hr (792 GPM) this valve size matches both size and flow requirements. Set valve to required design flow by checking specific size’s valve diagram. Find flow in the left column and follow a horizontal line to the fist reached pre-setting graph. In this example proper setting will be 6. Determine ΔpBV following a vertical line down from the inter-section between design flow and setting. From the specific valve diagram, ΔpBV is at a flow rate of 50 m3/hr (220 GPM) in setting 6 read to be 14 kPaD (2.03 psid).

The valve is used for medium flow control. Static balancing valves are designed to control hydraulic flow in HVAC systems. The valves can be installed in either supply and return pipelines when used as partner valve to a DPCV, the partner valve is installed in the supply and the DPCV in the return pipeline.
