What is Valve Flow Coefficient (Cv)? Kimray

WebJan 30, 2024 · A low pass filter should have a relatively large value for ( 1) and a very small value (ideally zero) for ( 2). For a high pass filter the opposite is the case. If both values are small (and if h [ n] is not zero) then it's probably a band pass filter, and if both values are relatively large, it's probably a band stop filter. WebThe valve flow coefficient (C v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters. The C v calculator will calculate either …
