Control Valve Basics - Sizing and Selection (Ohio T&M)
In Control Valve Basics - Sizing and Selection , you'll learn ...
- How to size a control valve
- Advantages and disadvantages of various types of valves and actuators
- Control valve theory, including flow coefficients, pressure drop, flashing and cavitation
- The three most common types of control valve flow characteristics and how they are applied
To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 200 minutes has been met.

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.
