I am modelling the closure time of an ESD valve against Hydrocarbon release inventory (pressure, volume of flow, mass flow rate) in a FBR condition.

I really want equations relating HCR parameters with closure time of a SDV. or graphs,chart and data showing relationship of HCR parameter with time. Can we also use the partial stroke testing to get all these information or is there any related past article on this?

Thanks

Unless you are modeling for the purposes of manufacturing a new valve, it would be best to contact the manufacturer, since all valves perform differently.

What information has the manufacturer of your valve provided you?

The following information were provided, Coefficient of discharge of the valve at various opening and closing angles for a quarter turn 150mm ball valve, but my headache is how to get all this to relate with actual time of closure of the valve.
