How do I calculate the valve rangeability from the datasheet?
Do I just take the flow rate at the max flow condition and divide it by the flow rate at the minimum flow condition? Or do I need you calculate the flow rate at full travel first?
I am supposed to calculate the flow of the process fluid through various control valves based on the valve opening. My boss says that the datasheet should be enough to calculate the Cv based on the valve opening which could then be used to calculate the flow. I know how to calculate the flow...
Hi, I am trying to calculate how much flow goes through a control valve that ends up as flare gas. I have used data sheets to identify thy type of control valve (linear, equal % or quick opening). I need a way to relate the flow coefficient (Cv) to the opening of the valve which will tell me how...
