This highly participative EuroMaTech training course is designed to provide participants with the skills to understand how valves and actuators are sized, selected and maintained, and how they operate in the most important industrial process plants, such as oil and gas, etc. Emphasis is also place on the important topic of steam traps, and the aspects related to this.

The Valves, Actuators and Steam Traps training course is interactive and encourages delegates to participate through questions and answers, along with opportunities to discuss with the presenter specific issues which may result in appropriate solutions.

Participants will learn:

  • How valves operate
  • Dealing with various control and other signals
  • The various classifications of valves
  • Different types of valves
  • Additional equipment associated with valves
  • Manual and software sizing of valves

  • Understanding the purpose, requirements and function of steam traps
  • Learning about the assortment of steams traps currently available
  • Dealing with steam trap selection, specification, safety factors, life-cycle costs, problems and management


The Valve, Actuator and Steam Traps training course will combine presentations with interactive practical exercises, computer simulations, individual exercises, group exercises, open and closed discussions, video presentations, paper exercise activities, case studies, individual understanding assessments after each chapter, and a comprehensive pre-and post-test, to ensure learning has taken place. Delegates will be encouraged to participate actively in relating their particular work requirements, problems and challenges at their workplace, and in assisting in finding solutions.

Adequate time will be allocated for group discussions, both during and at the end of each session. This will include detailed case studies and anecdotes based on the subject matter and the facilitator’s own experience in the field.
