Control valves are the workhorse of our facilities, continually functioning to ensure our systems work as intended. A properly specified, engineered, designed, installed, and maintained control valve can be one of the most profitable investments a facility can have, while a control valve that "does not work well" can be an increased risk of injury (more exposure of maintenance personnel working on the valve), and disruption to your system.
With today's focus on data management, the control valve is the part of the control loop that not only requires integration with modern data collection methods, but also involves mechanical features (moving parts, exposure to process fluids, material selection issues) as well as occupational health and safety issues not associated with other parts of the control loop (such as noise). Often the benefits of modern SCADA systems can be lost with inappropriate or minimal attention to the control valves.
This comprehensive certificate course covers the essentials of control valves and actuators. With this knowledge, the user is better placed to fully realize the full potential and benefit of any control system.
Selections of case studies are used to illustrate the key concepts with examples of real world working control valves. The course is aimed at those who want to get a solid appreciation of the fundamentals of their control valve design, installation and troubleshooting.

Benefits of eLearning to Employers
- Lower training costs: no travel or accommodation necessary
- Less downtime: short webinars (60-90 minutes) and flexible training methods means less time away from work
- Retain employees: keep staff who may be considering a qualification as full time study
- Increase efficiency: improve your engineering or technical employees’ skills and knowledge
- International insight: students will have access to internationally based professional instructors and students
How Does it Work?
EIT eLearning courses involve a combination of live, interactive sessions over the Internet with a professional instructor, set readings, and assignments. The courses include simulation software and remote laboratory applications to let you put theory to practice, and provide you with constant support from a dedicated Learning Support Officer.
Practical Exercises and Remote Laboratories
As part of the groundbreaking new way of teaching, our online engineering courses use a series of remote laboratories (labs) and simulation software, to facilitate your learning and to test the knowledge you gain during your course. These involve complete working labs set up at various locations of the world into which you will be able to log to and proceed through the various practical sessions.
These will be supplemented by simulation software, running either remotely or on your computer, to ensure you gain the requisite hands-on experience. No one can learn much solely from lectures, the labs and simulation software are designed to increase the absorption of the materials and to give you a practical orientation of the learning experience. All this will give you a solid, practical exposure to the key principles covered and will ensure that you obtain maximum benefit from your course.
