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.

Learning and Teaching

Benefits of eLearning to Students

  • Cost effective: no travel or accommodation necessary
  • Interactive: live, interactive sessions let you communicate with your instructor and fellow students
  • Flexible: short interactive sessions over the Internet which you can attend from your home or office. Learn while you earn!
  • Practical: perform exercises by remotely accessing our labs and simulation software
  • Expert instructors: instructors have extensive industry experience; they are not just 'academics'
  • No geographical limits: learn from any location, all you need is an Internet connection
  • Constant support: from your instructor(s) and a dedicated Course Coordinator for the complete duration of the course
  • International insight: interact and network with participants from around the globe and gain valuable insight into international practice 

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 Course Coordinator.

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.

Professional Development Series

In order to meet the exacting demands of the oil and gas, mining, manufacturing and downstream processing industries, modern plants are equipped with systems and devices which are needed to measure and regulate variables such as temperature, pressure, flow, humidity, liquid level, velocity and density. Industrial Automation provides the technology to control and monitor a process plant using such concepts as feedback, cascade, feedforward and advanced process control. Here at the Engineering Institute of Technology (EIT), we have developed industry-focused programs in the form of vocational diplomas, advanced diplomas and graduate certificates, all the way up to Masters level in the higher education sector.

There is a critical shortage of automation, instrumentation and control engineers, technicians and technologists around the world now due to the retirement, restructuring and rapid growth in new technologies and industries. The respected International Society of Automation (ISA) organization estimated that at least 15,000 new automation engineers are needed annually in the USA alone.

In keeping with the philosophy of EIT, students in this school are exposed to the practical, up-to-the-minute knowledge and skills demanded by leading industries worldwide, with online instrumentation courses. EIT does not just cater to a generic student body, instead all of our online instrumentation courses are specific to industry. The programs cover a large range of topics and are suited to anyone needing an intensive and practical look at all facets of industrial automation, instrumentation and process control.

The short courses that form part of EIT's professional development series are designed to provide students with critical knowledge and practical tools that can be immediately applied to the workplace. They are ideal to up-skill and/or cross-skill in a particular area or technology and are not accredited programs.

Students in EIT's School of Industrial Automation, Instrumentation and Process Control study subjects which include: process control, instrumentation, control valves, process plant layout and piping design, tuning of process loops, SCADA, PLCs, advanced process control (APC), boiler control, hazardous areas, safety instrumentation (IEC 61511 and IEC 61508), HAZOPs, industrial data communications, networking, deviceNet and Fieldbus, industrial wireless, radio telemetry systems, shielding/EMC/EMI, and noise reduction.
