This three-day course provides an introduction into the key aspects related to actuated valves. Actuated valves are commonly used as final elements in control- and safety systems, and play an important role in plant performance, reliability, and safety. Actuated valves are exposed to the often-harsh conditions of the process as well as to the ambient climatic conditions. Although the performance and reliability of most field instrumentation has developed significantly over the past decades, actuated valves have essentially remained the same. As a result, they have become a relatively large contributor to the overall plant downtime and operating cost.
