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 C v or flow using the supplied additional parameters of fluid, inlet and outlet pressure, and fluid temperature. The calculations can be performed for either liquid ... WebThe valve and port flow coefficient is highly dependent on the valve lift but nearly independent of the pressure ratio across the valve. Note that there is a loss in the flow coefficient when the manifold is tested along with the cylinder head. The loss is due to more flow restrictions introduced by the manifold.
