Control valves are needed in any system where fluid flow must be monitored and manipulated. A complete control valve is made of the valve itself, an actuator, and, if necessary, a valve control device. The actuator is what provides the required force to rotate the valve stem and the valve control device ensures appropriate position, interprets signals, and manipulates responses.
Selection of the proper valve involves a thorough knowledge of the process for which it will be used. When implementing a control valve into a process, one must consider not only the appropriate type of valve and its material of construction, but also the correct sizing to ensure it performs its designated task without any adverse impacts on the system.
This 4-hour course provides an overview of control valves with emphasis on sizing and selection. The primary audience for this course is chemical, mechanical, instrumentation and process engineers. However, the course will benefit any engineer who wishes to learn the basics of how to size and select control valves for process applications.
Learning Objectives
Upon completion of this course, participants will be able to:
- Differentiate among various types of valves and explain the benefits of each.
- Explain the operation of control valves in a control loop.
- Evaluate and apply actuators and positioners for specific applications.
- Explain the relationship among Cv, flow rate, and pressure drop.
- Size valves for flow conditions commonly encountered in a process plant.
- Select the appropriate valve characteristic for a given process.
- Explain how installed valve characteristics can closely match inherent characteristics.
- Describe methods for addressing system performance issues, including cavitation, flashing, and choked conditions.
- Identify the factors that influence control valve selection.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 25 questions. PDH credits are not awarded until the course is completed and quiz is passed.
