Butterfly Valve Cv sizing is the most widely used method for valve analysis used today. By using the Cv method, the proper valve size can be accurately determined for most applications when any three of the four following conditions are known or assumed: valve size, maximum flow, inlet pressure or maximum delta P.
By using the Cv webapp above, in conjunction with the Cv factors for a butterfly valve and the maximum allowable pressure drop, the resulting flow can be determined.
The webapp is used for water @ 60F.
