Control valves are the workhorses of facilities. They continually function to ensure systems work as intended.

The control valve is the part of the control loop that not only requires integration with modern data collection methods. It also involves mechanical features, as well as occupational health and safety issues not associated with other parts of the control loop (such as noise). 

A correctly specified, engineered, designed, installed, and maintained control valve can be one of the most profitable investments a facility can have. However, a control valve that “does not work well” can increase the risk of injury and disruption to your system. Often the benefits of modern SCADA systems can be lost with inappropriate or minimal attention to the control valves.

This Competency in Control Valve Sizing, Selection and Maintenance  course from the Engineering Institute of Technology  will help you understand what happens inside a control valve from a basic fluid mechanics point of view. This includes appreciating the difference between cavitation and flashing and realizing the difference between controlled and choked flow. You will also learn to choose between different characteristics on offer, understand the advantages and disadvantages of different seat leakage rates, and understand the failure modes for control valves and demonstrate new approaches to troubleshooting.

It will also cover how to recognize severe service applications and have an appreciation for the methods of tackling the problems associated with such applications. Plus, it will teach you to do simple calculations to determine control valve values, and identify the different types of control valves commonly in use and understand the relative advantages of each.

You will also learn to use a computer sizing program to assist with the selection of control valves, select materials for bodies, trims, packing boxes, and gaskets, and size actuators for linear and rotary applications and know the relative advantages of pneumatic, hydraulic and electric types.

Case studies will illustrate the key concepts through examples of real-world working control valves.


To obtain a certificate of completion for EIT’s Professional Certificate of Competency, students must achieve a 65% attendance rate at the live, online fortnightly webinars.  Detailed summaries/notes can be submitted in lieu of attendance.  In addition, students must obtain a mark of 60% in the set assignments which could take the form of written assignments and practical assignments. Students must also obtain a mark of 100% in quizzes.  If a student does not achieve the required score, they will be given an opportunity to resubmit the assignment to obtain the required score.
