This paper deals with the problem of selecting controllers and control valves for some of the most common chemical process control systems. Because a dynamic analysis can seldom be justified for most control systems, it is important to have some general rules for controller and control valve selection. An attempt will be made to present such general recommendations for flow, level, pressure and temperature control systems.
