Cv Calculation For Control Valve Engineering Toolbox. This is our valve c v calculator. The 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.
The valve flow coefficient, cv, is the number of u.s. This is not true for all types of control valves, however, and is also dependent on the valves. Cv = qg (g x t) 816 x p1 qg = cv 816 x p1 g x t note:
These workbooks include typical valve sizing and noise calculation parameters and typical tables of valve capacity (cv) for a number of the.
Online calculator to quickly determine valve and orifice cv & kvs values for steam. Example of pressure loss determination by cv rating on a certain valve a cv rating of 19.2 is published for water flow. Gallons per minute of water at 60°f that will flow through a control valve at a specified opening when a pressure differential of 1psi. If this valve is connected to a 125 psig air line, find the pressure loss through it when it is passing a flow of 243 scfm.
