The Cv value (flow rate factor or flow coefficient) determines the throughput of a fluid or gas through a valve. The Cv value serves as the basis for the choice and dimensioning of valves.
First select whether you wish to calculate the Cv value for a liquid or gas, then simply enter the required values.<br/>
These are simplified calculations; Hy-Lok D assumes no liability for the accuracy of the results. The results serve only for a basic assessment and can deviate from the real behaviour, particularly when considering gas flows. Choice, correct installation, material compatibility, intended use and maintenance remain the responsibility of the user. The whole system design has to be taken into consideration for reliable operation and optimum performance.
