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.
Explain the purpose and function of actuated valves.
Recognize different valve and actuator styles.
Select the right actuator size for an on/off valve.
Perform basic control valve sizing calculations and selection of the right trim.
Explain the function of the different components inside the valves and accessories on the outside.
Understand the function and operation of different types of solenoid valve and positioner.
Recognize application challenges for control valves - cavitation, flashing, choked flow, leakage, noise.
Understand those aspects that play a role in the selection of the most suitable valve and actuator style.
