For example a valve with a Cv of 10 will flow 10 GPM with a 1 psi pressure drop. The formula used to select the valve Cv with the specified differential pressure is: Cv=GPM/((SQ RT(∆P)). Control valve CV refers to the flow coefficient of the valve. It applies to the factor of the head drop (Δh) or pressure drop (ΔP) over a valve with the flow rate Q. Calculating control valve CV When Sizing (calculating which size valve is needed for your application) a control valve specialist needs to calculate the flow coefficient. Cv for FLUIDS Cv for liquids is the volume of 68°F water in U.S. gallons per minute that passes through a valve at a pressure drop of 1 PSI. Flow for a given Cv is typically calculated from the following formula. Where: Q = Valve flow rate in gallons per minute (US GPM) ΔP = Difference between upstream and downstream pressure in The operating point where the valve works the most open the CV is 319, as the Rated Cv is 400. Still, there is a certain margin of safety of oversizing.

The most common characteristic curves are the quick opening, linear, and equal percentage curves.

Originally developed to enable pulse-free fluid flow in dual-piston displacement pumps, the design is widely used in a range of high-pressure applications. CV valves are designed for use with 1/8” tubing or 1/4" tubing, depending on the model. Features of Vindum CV Valves Range of models: to 25,000 psi (CV-225) and 160C (CV-210, 410, and 510) The Cv corrected is equal to 10.96 while the valve selected has a Cv of 12.

If this Butterfly valve Cv values vary with the disc angle and valve size. In the chart below, we show the approximate Cv value of butterfly valves ranging from 2" to 24" passes through a valve at a pressure drop of 1 PSI. Flow for a given Cv is typically calculated from the following formula.

Kv = 0.865 · Cv Cv = 1,156 · Kv Cv Value & Flow Rate Calculator What is Cv value? The valve flow coefficient according to the JIS standard, represents the flow capacity in US gallons/minute of 60° F pure water when it is flowing through the valve with a pressure difference of 1 psi at the specified travel (operation range). Cv value and flow rate calculation In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution.
