Intelligent Rotary Control Valve: One Valve Numerous Applications


During recent decades, rotary control valves have encroached upon the traditional territory of the linear globe valve in the petrochemical industry. Eccentric plug valves in particular have established a firmfoothold in petrochemical applications. Ever increasing emphasis on environmental issues has meant that petrochemical companies are paying increased attention to emissions coming from control valves. This trend has made rotary valves more attractive because rotary valves typically have lower gland emissions than globe valves. In addition to low emissions, eccentric plug valves have proved to be suitable for numerous applications. Typical applications and opportunities, including their uses in the petrochemical industry, are considered.
