Your video quality and communication is top notch. Very good explanation and excellent content on pure practical engineering principles and processes. Keep up the great work!
At 1:30 it was said that the valve would have a lower CV as the valve tends to "close". Perhaps I am missing a point. I would say the valve is "opening" when traveling from 90 deg. to 10 deg. Thank you for this presentation.
Thanks for your support. Do you mean How to calculate Ball valve torque? most of time ball valve will use torque wrench to test valve operation torque. valve operation torque are difficult to calculate very accuracy.
Question: I would like to understand more on your tips that the valve more accurately between 30% to 80% opening, why is this so? Or does it actually depend on the valve trim configuration, and one must get advice from the valve manufacturer? Thank you, this is a very good video..
Can we have a video to calculate a circuit from a pump to a pipeline to a control valve and to the heat exchanger? How much is the pressure drop through the pipeline ,control valve and the heat exchanger
thank you but i have a question here you have said the max CV is at 70/100 of valve opening , so if the valve gets 100/100 of opening what we can say about CV in this case? wich value will take?
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??
