Fisher Control Valve Sizing Software Firstvue Firefox

Most free or very low cost sizing and selection software given away by a vendor is generic by nature and won't contain all the selections that their in-house propriatary sizing software will give them. First, they can't trust that untrained persons will fill in all the really technical but necessary parameters needed to make a proper selection, and: Second, they don't know where those programs will end up, and they certainly don't want their propriatary designs to end up on the desk (computer) of their competitor. You are probably not going to get much more than you could calculate by using standard engineering references like Perry's, Marks, Crane, Cameron Hydraulic, et. But at least the software will take the tedium out of the process, and allow you to use modern tools. So, use anything you get with that in mind. Still, most of them will allow you to do some decent process evaluations, etc., and run it over and over until you get it close. Rmw RE: Valve sizing programs (Petroleum) 12 Aug 05 04:23.

Hi cliff6361, I am not quite sure how you are going to use 'this control valve sizing program', or if I understand quite what you mean by 'valve sizing program'. However, here are some thoughts: Each valve that you chose will have a Cv number that you need to get from the manufacture. Fisher, for example, in their FirstVue sizeing program includes this, and you are then able to match your Cv requirement to the valve's Cv. I would think that other vendors's sizing program does the same. This would mean that if you plan to buy a Fisher valve, you most likely would want to use their sizing program, and the same for each other valve manufacturer.

Soul deep chords by the box tops. On the other hand, if you mean a 'valve sizing program' to determine what the required Cv of the valve would need to be, then that is a different type of program. That is almost into the realm of a process simulator/modelling progarm. In this case, you are looking at flowrates, upstream/downstream pressures, including pumping curves etc. To determine the max/norm/min flow conditions to determine the range of Cv for the valve. If this is the case, there are vendors such as Aspen/Hyprotech that sell packages that may meet your needs. Hope this helps.

RE: Valve sizing programs. In order to specify a control valve a program such as AFTs Fathom can be used. Especially if you use their goal seeking and extended time simulation modules. Then you will be able to specify to the control valve vendor what the process conditions are to be met.

The best use of vendors software is to check the salesmens figures. Some are better than others. In my experience it has been preferable to establish a relationship with a control valve company so that you can trust them.

Fisher valves, actuators, regulators and instrumentation solutions increase. Control Valve Sizing & Selection. Fisher control valve installed in pipeline.

Even then check their interpretation of your figures. They can make mistakes as well. If you have a relationship then even their mistakes can be forgiven. You cant expect the control valve company to be responsible for your process nor they expect you to be responsible for their product.

Its the grey area in between that both parties need to be adequately informed. Dot be tempted to save a few bob and leave all to the salesmen. RE: Valve sizing programs.

The Fisher valve handbook has got their valve sizing equations in it and I just made up a spreadsheet for myself to use including the effect of cavitation on valve sizing. It's not nearly as powerful as the vendor's program of course but it's more than adequate when I want to estimate the Cv required and what size valve I'm likely talking about. It was enough to caught a mistake when our instrument engineer was sizing a control valve based on my min/normal/max conditions and I did a quick check of the Cvs and they weren't even close. Turned out somehow he had mixed up the outlet pressure for the cases and used them in one calculation while showing them in the 'correct' column(s) on the data sheet. I'm not quite sure how he did that but he didn't believe me until I got him to use his program and the conditions for a given case and lo, the calculated Cv didn't match the data sheet's condition but matched my spreadsheet value.
