Actual pressure loss at the indicated flow can be calculated using the Kv value, which indicates flow at 1 bar differential pressure:Δp = Pressure loss in bar2Q = Flow in m3 / hKv = Kv – Value at Δp = 1 barNominal flow qp m3/hMounting lengthConnecting threadPressure loss at qp mbarKv value at Δp = 1 bar m3/hCurve in the diagrammm0.6110, 190G ¾, G 1, DN201501.5A1.5130, 190G1, DN201603,8B1.5110G ¾1503,9C2.5190G1, DN202105,3D2.5130G 12005.6E3 CE2N5324en 2018-08-181000r a b m n250i s s o100l e r u s s e r P100.14 Building TechnologiesNominal flow qp m3/hMounting lengthConnecting threadPressure loss at qp mbarKv value at Δp = 1 bar m3/hmm3.5260G1¼, DN25
