Thank you very much.

What about a multipath cage design and a shrinking cage design?

I did an analysis under minimum conditions. I gave 82 bar to the inlet and 36 bar to the outlet and opened the valve to 20%. Cv 11 and automatically calculated the flow rate as 2600 m3/h. When I gave 82 bar to the inlet and 10,000 sm3/h flow rate to the outlet, the Cv value I obtained was 36.5...

Unfortunately, the customer wants one size valve.

I have never analyzed under minimum conditions. normally maximum conditions: 37-36 bar and 100000 sm3/h flow but when I define the inlet-outlet pressure in the program, it automatically calculates the flow rate and calculates 10000 sm3/h. for your information.

I have never taken the minimum as a basis until now because my aim is to see the rated Cv value. for this reason, either by giving the inlet-outlet and seeing the flow rate or by giving the inlet pressure-outlet flow rate and seeing how much pressure drop the cage provides. I was not sure which...

this is a continuation of my other work, you think right. but I'm not sure how to give the flow rate. this is the first time I'm hearing from you. what I can't understand is, from 37-36 bar pressure, should I get a maximum flow rate of 100,000 sm3/h to pass through? or should I get 36 bar...

at first I chose 10“ but due to the deadline we had a 12” valve ready. that's why I chose it. they want the speed especially low. then I thought I would lower the cv value with the cage design. that's why I asked about CFD in another topic.

I want the valve to provide the maximum flow rate by entering the specified inlet and outlet pressures. at worst I want it to be close to the maximum flow rate.

When I give it as volumetric inlet and pressure output, the inlet pressure starts to rise to very utopian values and it gets ridiculous. for this reason, I give pressure to the inlet and flow rate to the outlet, which is correct according to both formulas. my understanding; when I give inlet and...

the customer asked for a maximum flow rate of 20 m/sec. he said that was important for him. how did you calculate the speed?

Hello; the parameters required from a control valve are inlet and outlet pressures, flow rate and temperature. when analyzing I can only specify 2 boundary conditions: either inlet pressure+flow rate or inlet pressure+outlet pressure. which one is more correct? because I cannot give flow rate...

As a result of my analysis, when I gave 37-36, ie dp=1 to the inlet and outlet, the flow rate of the valve was 10000. the desired flow range is 10000-100000 sm3/h. of course, I determined the minimum and maximum conditions by myself. would it be too big? can't I control it with a cage?

My maximum conditions are as follows: pipeline=16” p1=37 bar p2=36 bar Q=100000 sm3/h T=15 C Vmax=20 m/sec I chose 2 lower ones as an estimate. The rated cv value of my 12” c600 axial valve is 1550. The Cv value I calculated is about 500. there is a big difference. Do you think this valve is...

I work for a supplier but why not use the fisher calculator? I don't understand. there are a lot of cv calculators on the internet and the fisher handbook has all the information on the internet about valve sizing.

my friend, the information has been updated. Pipeline=16” p1=82-36 bar p2=66-36 bar Q=10,000-100,000 sm3/h T=15 C Vmax=20 m/sec the important thing for them is to ensure the necessary flow. when I calculate it in the sizing calculator on the fisher site, the Cv is too small. My understanding...
