valve cv calculator

Control valve sizing and flow coefficient Cv calculator ... Control valve calculator is suitable for turbulent flow of liquids. The calculator is calculating flow coefficient Cv Kv using the relationship between pressure drop and flow rate in the control valve which is for complete turbulent flow following power law where flow coefficient Cv Kv is the proportional constant. Cv Calculator | Swagelok C v Calculator for Valve Sizing. This calculator can be used to help select a valve with enough flow capacity for a given application. 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 ... Calculator: Valve and Orifice Cv & Kvs Values for Water ... Online calculator to quickly determine Valve and Orifice Cv & Kvs Values for Water. Includes 53 different calculations. Equations displayed for easy reference. Valve sizing calculator | Tameson Kv value calculator fluids. Fill a value for the inlet pressure, the outlet pressure and the minimal required flow rate. Click calculate and the Kv and Cv value will be calculated. Choose a valve with a Kv value equal or higher than the calculated value. Control Valve Relation between Cv and Kv | Cv = 1.156Kv Q = Flow in m3 hr., Δ P = 1 bar, SG = 1 for water at 15°C (Equivalent of 60°C Imperial units) In metric units, the same valve with Cv = 1 pass 0.864 m3 hr. (at 15 °C) with a delta P of 1 bar across the valve. Summary : For any specific valve opening with an equivalent pressure drop and equivalent temperature, by applying multiplication factor we get equal flows in both Imperial and metric ... Cv Value & Flow Rate Calculator｜Product & Technical ... 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). Gas Sizing | Kimray * For All Non Venting Back Pressure and Non Venting Pressure Reducing Regulators, small pressure drops reduce the Cv of the valve: Pressure drops of 3 psi or less, multiply valve Cv by 0.5; Pressure drops from 3.01 to 6 psi, multiply valve Cv by 0.8; Pressure drops from 6.01 to 12 psi, multiply valve Cv by 0.9 ** with Removable Seat Engineering Calculator | TLV A Steam Specialist pany ... Engineering Calculator Over 50 calculations for steam, water, air and gas systems. TLV ToolBox For iOS and Android. Steam. ... Cv & Kvs Values Steam Flow Rate through a Valve Steam Flow Rate through an Orifice. Condensate Load. From Piping at Start up From Heating Liquid (Continuous) ... Control valve A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.. In automatic control terminology, a control valve is termed a "final control element". 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 C v (or flow capacity rating of valve) can be expressed as : = where: Q is the rate of flow (expressed in US gallons per minute), Check Valves | Generant Generant manufactures a wide selection of check valves to address many diverse application requirements. Generant check valve products are offered in several series ranging from ultra low cracking pressures widely used in medical devices, products optimized for cryogenic applications and severe service designs with MAWPs up to 10,000 PSI. Gas Flow Calculator | AP Tech A broad range of manual valves is available with pressure ratings up to 4,500 psig (310 bar) with line sizes to 1 inch. The wide variety of actuation types combined with lock out tag out (LOTO) options, sizes and pressure ratings provide the valve for most requirements. Flow Coefficient C v for Liquid, Steam and Gas ... Example Flow Coefficient Liquid. The flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch pressure drop can be calculated as:. C v = (25 gpm) (1 (1 psi)) 1 2 = 25 Flow Coefficient C v for Saturated Steam Since steam and gases are compressible fluids, the formula must be altered to accommodate changes in ...

Flo well Calculator Valve & Meter Boxes Available in a wide variety of sizes, colors and designations, all NDS boxes and lids contain UV inhibitors for sustained durability and performance in direct sunlight. Learn More New Consolidation What is Ball Valve ? | Ball Valve Parts | Ball Valve Stem ... A ball valve is a rotational motion valve that uses a ball shaped disk to stop or start fluid flow.. The ball, shown in Below Figure, performs the same function as the disk in the globe valve. When the valve handle is turned to open the valve, the ball rotates to a point where the hole through the ball is in line with the valve body inlet and outlet.
