Cv Factor For Valves. For example, a valve with cv of 4.00 will pass 4 times as much flow at the same pressure difference as shown in the chart. This calculator can be used to help select a valve with enough flow capacity for a given application. Cv & kv relation : A valve cv can be described as the number of gallons per minute (gpm) at 60 o f (15.5 o c) that will pass through a valve with an associated pressure drop of 1 psi.

Butterfly valve cv values vary with the disc angle and valve size. The required cv range for this application than is.0141 to.0703. 6.4 “a” constant for 80 psi, from table 2. Cv flow coefficient ratings have several advantages: Cv & kv relation : On valves or orifices with other cv factors, the flow capacity will be directly proportional to the cv rating.
They simplify the job of selecting an adequately sized valve without wasteful oversizing;
8.30 x 12 x 6.4 x.048 cv = 1 x 28.8 = 1.06 any valve, therefore, which has a cv of at least 1.06, will extend our cylinder the specified distance in the required time. C v calculator for valve sizing. Cv is based on the volume flow rate of water at 60°f through a device within one minute at a 1 psi differential. 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. With the flow coefficients capacities of valves at different sizes, types and manufacturers can be compared. The flow factor is commonly used outside u.s.

The complete definition also says that the flow medium must have a specific gravity of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s. Sometimes, the cv value is given instead of the kv value. The cv rating for each valve is listed in the tables found in the valve catalog. It allows you to calculate the flow or c v (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points in a network transporting a liquid or gas) and the flow rate. With the flow coefficients capacities of valves at different sizes, types and manufacturers can be compared.

A cv of 1 then, means that one gallon of water passed through a valve in 1 minute. This is used as a guide and is not a linear progression. Butterfly valve cv values vary with the disc angle and valve size. The below cv values are used to give an indication of flow rates for ball valves. The full closure curve of a ball valve is then the above graph multiplied by the valve’s flow coefficient or factor.

It can be assumed that the tests are done with water (unless otherwise noted), using a specific gravity of 1.0, 1.2 centistoke viscosity, and a standard temperature of 60 degrees fahrenheit. Butterfly valve cv values vary with the disc angle and valve size.

Kv = 0.865 · cv cv = 1,156 · kv (equivalence between flow coefficients kv and cv) When sizing a control valve, the most common approach is to calculate the flow coefficient, cv which is a measure of the capacity of the valve body and trim. This calculator can be used to help select a valve with enough flow capacity for a given application. Because air is compressible, cv must have additional factors built into the equations to compensate for that compressibility.

The valve flow coefficient, cv, is the number of u.s. Valves are tested by running water through it before publishing the cv value. If differential pressure is same, flow rate is big so that cv factor is big. A simplified version of the definition is: Cv is the flow coefficient in imperial units.

Contrast this with the resistance factor k (the one used for pipe fittings like bends etc). The following formula is often used using a fluid’s specific gravity (g) where the relationship to water density is already considered. 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. In the chart below, we show the approximate cv value of butterfly valves ranging from 2 to 24 and at various disc angles.
