What is Valve Flow Coefficient (Cv)? | Kimray Valve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it. It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.” In simpler terms, the larger the opening in a valve, the larger the Cv. What is Flow Coefficient (Cv), and Why You Should Care The Cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system. It is a number published by the valve manufacturer that describes the number of U.S. gallons that can pass through a valve (in a fully open position) at a pressure drop of 1 PSI. Why You Should Care The Valve Flow Coefficient (Cv) ~ Learning Instrumentation ... The valve flow coefficient, Cv, is the number of U.S. 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 is applied across the valve: The metric equivalent of Cv is Kv, which is defined as the amount of water that will flow in m3 hr with 1bar pressure drop. Control valve flow coefficient Cv Kv Valve sizing ... The flow through a valve can be calculated thanks to the pressure drop through the valve and a coefficient Kv which represents the number of m3 h of water that goes through the valve at 15c and with a pressure drop of 1 bar. What is the flow coefficient Cv? pneumatictips Cv is based on the volume flow rate of water at 60°F through a device within one minute at a 1 psi differential. However, there is a problem with using this equation in pneumatic applications. Because air is compressible, Cv must have additional factors built into the equations to compensate for that compressibility. Flow Coefficient C v for Liquid, Steam and Gas ... The flow coefficient Cv required for a specific application can be estimated by using specific formulas for the different fluids or gases. With an estimated Cv value the correct size of control valve can be selected from the manufacturers catalogs. Flow Formulas & Cv Factors Magnatrol The valve's flow coefficient, Cv, is a value that is determined by flow testing for each valve size. Full port valves will have a higher Cv than reduced port valves. The Cv rating for each valve is listed in the tables found in the valve catalog. Cv Calculator | Swagelok 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 pressure, and fluid temperature. Teesing Flow and CV calculator The use of this flow coefficient (Cv) calculator leads to a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have an important influence on the performance of the assembly for transferring gas or liquids in a system. Cv and Kv Flow Coefficients Pipe Flow Software A Cv flow coefficient specifies the amount of water at 60°F (15.55 °C) in US gpm that will flow through a valve and produce a 1.0 psi pressure drop. Thus a Cv flow coefficient of 10 indicates that a 1.0 psi pressure drop will occur with a 10 US gpm How to Use Flow Coefficients (Cv) for Hydraulic Fluids ... The most common usage of the Cv flow coefficient is to predict the pressure loss to be expected across a valve while fluid is flowing through it. The Cv rating published by the valve manufacturer is used for this determination. If the Cv is stated in terms of water flow, it must be corrected for viscosity and specific gravity of other fluids. Control Valve Sizing FluidFlow | FluidFlow The flow coefficient or valve coefficient denoted by “Cv”, is used to determine the valve size that will best allow the valve to pass the required flow rate while providing stable control of the process fluid. Most valve manufacturers publish Cv data in product catalogues for various valve styles. Flow Coefficient, Cv, to Flow Factor, Kv, Converter – My ... Flow coefficient, Cv, and Flow Factor, Kv, are values used to specify the hydraulic capacity of a control valve. Flow coefficient is an imperial measurement and is defined as: the flow of water through a valve at 60°F in US gallons minute (gpm) at a pressure drop of 1lb in². Flow coefficient The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow capacity rating of valve) can be expressed as : Flow Coefficient Values Cv Values of Ball Valves The coefficient of flow or C v Value is the number of US gallons of water the valve will pass with a differential pressure of 1psi through the valve at 60F. K v is the metric value of C v and is calculated as K v =C v x 0.85. Cv Value & Flow Rate Calculator|Product & Technical ... 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 Flow Coefficient, Opening and Closure Curves of Full Bore ... Cv & Kv Fraction vs Angle Closure Curve Chart This graph shows the Cv or Kv valve fraction vs opening and closing angle of a full bore ball valve: The full closure curve of a ball valve is then the above graph multiplied by the valve’s flow coefficient or factor. Cv vs Angle Closure Curve Values Table Controls and Accessories | CV Flow Control | CV Flow Control The CV Control is an adjustable restriction which acts as a needle valve when flow is in the direction of the stem. When flow is in the reverse direction, the port area opens fully to allow unrestricted flow. Control valve CV: what it means and how to calculate it ... 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. The formula will differ depending on the product the valve regulates, such as liquid, gas, or steam. Flow Coefficient C v versus Flow Factor K v Related Topics . Steam and Condensate Steam & condensate systems properties, capacities, pipe sizing, systems configuration and more; Control Valves Control Valve terminology, bodies, trim, flow characteristics, Cv and Kv sizing, noise, actuators and positioners; Fluid Mechanics The study of fluids liquids and gases. Involves velocity, pressure, density and temperature as functions of ... Ball Valve Flow Rates Valvesonline The below CV values are used to give an indication of flow rates for ball valves. CV value is an imperial measure of flow in US gallons per minute of water at 60° fahrenheit with a pressure drop of 1 psi across the valve. This is used as a guide and is not a linear progression. Flow Capacity Cv Flow Coefficient | Maxbar AFP ... What is the CV of a Valve? The flow coefficient or Cv of a coupling is defined as the volume of water in US gallons per minute that will flow through the coupling with a pressure drop of 1 psi. In other words, flow capacity is a measure of efficiency at allowing liquid to flow. The use of the flow coefficient offers a method of of comparing ... Cv and Your Pressure Regulator | ControlAir Engineers who are designing or implementing a valve are aware of its Cv, or otherwise known as Flow Coefficient. This value is a coefficient used to predict flow through a particular valve based on a specific pressure drop across it.

The Valve Coefficient (Cv – in Imperial unit) – the number of US GALLON PER MINUTE of water at 60 °F that will flow through a valve at specific opening with a pressure drop of 1 psi across the valve. Is valve Cv important for on off control? | Caleffi A smaller Cv will have a higher close off rating, however, it will also decrease the flow capacity of the valve and add head loss to the system. Verify that the flow capacity is sufficient for the load and verify the added head loss is still acceptable. Here are the equations to use: Q = flow (GPM) Cv = valve Cv How to calculate the flow coefficient of a valve In the past couple of months I have seen two examples of customers interested in the calculation of the flow coefficient of a valve. Known as Cv, the flow coefficient is a relative value that allows us to compare the efficiency of different valves regardless of their size or type.
