ASCO Flow Calculator The ASCO flow calculator is a helpful tool. ASCO VALVENET ... ASCO Introduces 068 Series Flapper Isolation Valve Improves Throughput, Reduces Sample Size in Clinical and Analytical Instruments; What is Valve Flow Coefficient (Cv)? Kimray Blog Valve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it. Basically, the larger the opening in a valve, the larger the Cv. As a valve is opened more and more, the Cv increases until the valve is fully open, where it reaches its highest possible Cv, or 100% open Cv. Control valve sizing and flow coefficient Cv calculation 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: Pneumatic Control Valve Sizing Guide 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. Choosing the Valve “Series” Your next step is to choose a basic valve design to do the job. For a quick guide to valve designs, see Table 3. Having selected the basic valve design, consult the Control Valve Cv Excel calculation Tool Liquid, Gas, Steam 1. Introduction Calculate the required flow coefficient Cv of control valves thanks to this Excel calculation tool. Simply input the valve data and the flow data flowrate, pressure, temperature when relevant then the tool will calculate the Cv required for getting the required flow at the required pressure drop. Control Valve Excel Worksheets Control Valve Application ... A unique feature of these worksheets is that in addition to performing traditional Cv calculations, they can also graph the installed flow characteristic and installed gain of a valve when it is installed in a particular system. These worksheets are based on ANSI ISA 75.01.01 (IEC 60534 2 1 Mod) 2012 "Flow Equations for Sizing Control Valves." 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. Calculating control valve CV.

Control Valve Sizing For Steam Systems | Spirax Sarco plicated equations are required to calculate noise emitted from control valves and these are difficult to use manually. It is usually considered that the control valve will produce unacceptable noise if the velocity of dry saturated steam in the control valve outlet is greater than 0.3 Mach. The speed of sound in steam will depend upon the ... Flow Calculation for Gases Ideal Valve Flow Calculation for Gases The coefficient of flow (Cv) is a formula which is used to determine a valve’s flows under various conditions and to select the correct valve for a flow application. The Cv was designed for use with liquid flows, it expresses the flow in gallons per minute of 60º F water with a pressure drop across the valve of 1 psi. Control Valve Sizing Calculator Gases Related Topics . Control Valves Control Valve terminology, bodies, trim, flow characteristics, Cv and Kv sizing, noise, actuators and positioners; Process Control Instrumentation and process control systems, design and documentation; Gases and pressed Air Air, LNG, LPG and other common gas properties, pipeline capacities, sizing of relief valves How to Convert CV to GPM | Sciencing Flow coefficient (Cv for control valve) is the capability of a valve to flow a liquid. One Cv is equal to a flow of 1 gallon per minute (gpm) of water at 60 degrees Fahrenheit with a pressure differential of 1 pound per square inch. The larger the Cv, the greater the flow in gpm.
