Thank you. Is it common to have more than a 1 psi drop in the valve? For ex if I have a valve at cv4 could I have a 4psi drop on it instead of 1? I have a chilled water coil that is supposed to have 8gpm flow with a valve that has a CAV of 4
Hello, you can find the formula for each on the Sizing calculators page. Just click on the type of sizing from the dropdown menu, then the “view formula” button.
Suppose I want to add a valve on a pipping line, I know P1 using pressure gg. But how about P2? Flowrate I could measure from flowmeter. Just dont understand what value of P2 I should put in the calculation
@Rob Hernandez: If I change the pump, which delivers at different pressure. Dont the actual flow go wrong since the DP across the valve changes. Please let me provide me a proper link at jaganmohanraor@gmail.com
Hy... I have one doubt in equation which is usually seen in valves catalog P =( (36 x Q) / Kv) ^ 2 P - KPa Q - L/s I would like to know how 36 constant came?? If it is conversion of l/s to m. Cube/hr, it is 3.6...how it become 36??
Hello, is that equation from a different source? I'm trying to understand where it came from. Which formula are you referring to and where did you see it?
@@KimrayInc hy Kim...thanks for the response... i found this equation from Flowcon valves catalog to calculate the pressure drop across a valve section.
I don't think we would be able to best answer questions about another company's sizing formula, unfortunately. I'm glad you were able to dig deeper into the information and come up with new questions at least. Please let us know if we can help any other way.

Thanks for this video. This is the best explanation I've come across. Very easy to understand.
Follow along with the written blog about CV here: blog.kimray.com/what-is-valve-flow-coefficient-cv/
I appreciate the information!
Thank you for informing the consumer!
Very helpful quick tips in practical settings. That plus the most attractive narration! Loving it more and more 🙋🙋
Glad to hear you found it helpful! There's always more to come!

Really very usefull videos
What about measuring Gas CV? is that the same formula?
Hello, you can find the formula for each on the Sizing calculators page. Just click on the type of sizing from the dropdown menu, then the “view formula” button.
@@KimrayInc why Temp. has no any indication in formula for CV calculation in gas however Temp. should be an important input in calculation
very good video Thank you for teaching!
I Subscribed :)
Thank you so much, that's a great compliment and a big help to our channel!
Where is this Software??

P - KPa
Q - L/s

@@KimrayInc thanks man
Can i get this sizing chart?
Glad to help - the sizing calculator is available here on our website: kimray.com/Sizing
