Calculate flow factor Kv for liquids, steam and gases - metric units. By using the capacities of valves with different sizes, different types and from different manufacturers - can be compared. is in general determined experimentally expressing flow capacity in metric units - that a valve will pass for a pressure drop of = q (ρ / (1000 (p(1)

Click calculate, and the Cv value and Kv value will be calculated. Choose a valve with a Kv-value equal to or higher than the calculated value. Gas: Choose a gas type and the inlet temperature. Choose the inlet pressure, the outlet pressure, the required flow rate, and click calculate.
Why we Measure Control Valve flow coefficient (Cv) ? Valve Cv or Kv
Conversion formulae for Cv and Kv. It is possible to convert between the flow coefficients Cv and Kv. Kv = 0.857 * Cv. Cv = 1.165 * Kv. FAQs What is flow coefficient Cv for valves? The flow coefficient, also known as the Cv value, is the flow rate of water in U.S. gallons per minute (GPM) at a temperature of 60 𐩑F with a pressure drop of 1.
Flow Simulation coefficient de débit (CV/KV)
1. What is the Cv and Kv of a control valve ? Cv and Kv are 2 coefficient allowing to relate the pressure drop through a valve to the flowrate of fluid going through. Cv is commonly called the flow coefficient and Kv is commonly called the flow factor. They have very similar meaning but not exactly the same definition.

C v and K v are singles values in units of flowrate that may be used to characterise the relationship between flowrate and pressure loss for fittings and equipment. This article demonstrates how to calculate the C v or K v values, and how to use these values to determine the pressure loss for a given flowrate. Definitions Introduction

Kv is the flow coefficient in metric units. It is defined as the flow rate in cubic meters per hour [m3/h] of water at a temperature of 16 celsius with a pressure drop across the valve of 1 bar.

Finally, we will compare Cv and Kv, two commonly used flow coefficients, and provide guidance on choosing the right flow coefficient for your needs. Understanding Flow Coefficient (Cv) The valve flow coefficient, often denoted as Cv, measures the fluid flow rate through a control valve.
What is Kv/Cv? How to calculate Kv/Cv?
Kv is measuring the flow of water under a pressure drop of 1 bar, at 5-30 c. It is expressed in m3/h. 2. Conversion in between Cv and Kv How to convert Cv to Kv or convert Kv to Cv ? It is possible to convert Cv and Kv with the following formula : Cv = 1.16*Kv Kv = 0.862*Cv 3. Valve Cv Excel calculation tool Link to Excel calculation tool
How To Know The Cv Or Kv Of A Control Valve Act4apps
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.
