A challenge with controls – specifically, with advanced control systems – is the installed characterizations of control valves. Often times the actual installed characteristics are different from what the published characteristics state, or, frankly, the information is no longer available. Additionally, a common practice is to manipulate the valve from 0 to 100% while watching the flow, but this is difficult to do while keeping the system online.   

In this poster, I show a use case for the profiler and the simulator where historic data can be used to create valve characterization curves without impacting the plant operation. These curves can then be used to improve plant control networks or even help deploy advanced control systems.
