Fisher Control Valve Sizing Calculator Fisher Control Valve Sizing Handbook A valve sizing program for control valve. Developed and refined for many years.

Anand: The control valve sizing programs check for flashing and cavatitation. Equations could be found in texts and manufacturers literature. You could discuss this with your local control valve suppliers. The control valve estimates of flashing and cavitation can be overstated.

The best way to determine the percentage of flashing is to ask a Chemical Engineer to analyze this on a process simulator and give you the percentage. Control valve sizing programs are available from manufacturers, for free. Usually they will analyse your application and present solutions.

As with some of the other posts, you really need to check with specific data for your valve. However, you can do a very simple check to see if you are likely to have problems. If you can find a value for your proposed valve of the Pressure Recovery Coefficient FL, you can estimate the minimum pressure at the valve throat. Flytampa Boston V3 Fsx News. Minimum pressure = Upstream pressure - (Pressure drop over valve/FL^2) If this pressure is close to or less than the vapour pressure of the liquid, you have a problem.

Failing specific valve data, FL for a globe valve is about 0.85; for a butterfly 0.65; and for a ball 0.5 But don't take my word for it - if money is to be spent on this, make sure the valve supplier makes a commitment to the result in writing. (Then when the valve develops wormholes through cavitation, you have a chance of some redress!) Bruce. You have clicked on the '?' Button for search help.
