Online calculator to quickly determine valve and orifice cv & kvs values for air. As the stem opens, the cv increases. Kv = 0.864 cv at a particular percentage of opening of valve giving cv = 1 will pass 1us gpm ( at 60 °f) and a pressure differential of 1 psi upstream and downstream across the valve. I believe that kv is the metric equivalent to cv. Founded at 1980, value valves co., ltd.
Cv Value For Valves. Size 150 300 600 900 1500 2500 2 42 42 42 45 38 25 2.5 67 67 67 / / / 3 100 100 100 90 95 65 4 185 185 185 170 170 1005 6 440 440 440 400 395 265 We recommend you select a valve for which the cv falls between 20% and 80% open stem travel. For the same pressure conditions, if we increase the valve opening to create cv = 10, it will pass 10 us gpm provided 1 psi pressure drop across the valve (remains same). 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).

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. Q is the rate of flow (expressed in us gallons per minute), sg is the specific gravity of the fluid (for water = 1), δ p is the pressure drop across the valve. The process of valve size selection, the same formula is used determine the valve cv necessary for a required flow rate and desired pressure drop. Kv = 0.864 cv at a particular percentage of opening of valve giving cv = 1 will pass 1us gpm ( at 60 °f) and a pressure differential of 1 psi upstream and downstream across the valve. Butterfly valve cv values vary with the disc angle and valve size. We recommend you select a valve for which the cv falls between 20% and 80% open stem travel.
Specializes in the manufacturing and servicing of a full range of sleeved and lined industrial plug valves.
It is defined as the flow rate in us gallons per minute [gpm] of water at a temperature of 60º fahrenheit with a pressure drop across the valve of 1 psi. The valve flow coefficient cv or its metric equivalent kv has been adopted universally as a comparative value for measuring the capacity of control valves. This is used as a guide and is not a linear progression. Nosuch6_wp march 2, 2017 0. On the right, we have a cv chart showing flow curves for two different valves: Can anybody educate me on how i go about calculating cv coefficient values for relief valves.

It is used to determine the appropriate sizing of the valve as well as evaluating the flow kinetic energy in regards with process and piping integrity. It is defined as the flow rate in us gallons per minute [gpm] of water at a temperature of 60º fahrenheit with a pressure drop across the valve of 1 psi. Table below provides cv values of fully opened ball valves and are approximate values. C v calculator for valve sizing.

The coefficient of flow or cv value of ball valves is the number of us gallons of water the valve will pass with a differential pressure of 1 psi through the valve at 60°f. The below cv values are used to give an indication of flow rates for ball valves. I know the calculation differs depending on the state of the medium that is to flow through the valves, and it is also related to flow and pressure (upstream and downstream). Cv = (25 gpm) (1 / (1 psi))1/2. Table below provides cv values of fully opened ball valves and are approximate values.
