PVC-U Angle seat check valves – VI series PVC-U Valvole di non ritorno a sede inclinata – serie VI Pressure loss / Perdite di carico Flow rate coefficient Kv100 / Coefficiente di flusso Kv100 At ∆p = 1 bar. Kv100 flow coef?cient is the flow rate of water at 20°C that will generate 1 bar pressure drop. The Kv100 values in the table are calculated for the valve completely open. Per ∆p = 1 bar. Il coef ciente di flusso Kv100 è la portata dell’acqua a 20° che genera una caduta di pressione di 1 bar. I valori del coef ciente Kv100 riportati nella tabella sono riferiti alla valvola completamente...
