The control valve usually should not be the most restrictive element of the process, but it also should not be oversized or have performance issues that do not mesh well with the process characteristics. Typically when a valve is selected, attention is paid to whether the valve is the correct size by determining the travel of the valve (openness) at several operating points. Often these are labeled minimum, normal and maximum. From these conditions, suitability can be judged by seeing that certain rules of thumb are followed.
