DIMENSIONAMENTO DELLE VALVOLE (LI- QUIDI) Il coefficiente di efflusso Kv indica la portata in m3/h con una perdita di carico di 1 bar quando la valvola è completamente aperta (acqua a 20°C). Il valore Kv si calcola utilizzando la seguente formula: DN25 S19 EQP DN25 S12,7 EQP
VALVES SIZING (LIQUIDS) The flow coefficient Kv indicates the flow capacity in m 3 /h with a pressure drop of 1 bar when the valve is completely open (water at 20°C) The Kv value is calculated with the following formula:
