It is irrelevant whether delegate valve knowledge and experience range from novice to advanced. The workshop starts from first principles, and builds up, with the emphasis on delegate participation. Instructor guidance is delivered on a personal level, and delegates are encouraged to ask as many questions as necessary. This training course is suitable for a wide range of professionals but will greatly benefit:

• Instrumentation, electrical, mechanical, process and maintenance engineers, specialists and staff
• Management
• Design teams
• Budgeting and financial staff
• Team leaders, supervisors and foremen

This course delegates with all the necessary knowledge to enter the world of valves and actuators. The workshop is highly interactive, and is suitable for all delegates, regardless of their background. Whether you are part of the team purchasing the valves, or a key member involved in implementing maintenance activities, or a process control specialist, this is the one course that you should not miss out on! Valves, actuators, associated equipment, process control using valves – this and much, much more are covered in 5 knowledge-filled days. The training course focuses on applications and examples deemed to be relevant to the industry and it is cognizant of the delegate’s working environment. At least 50% of the workshop is devoted to practical exercises and discussions, to keep attention spans at optimal levels. This training course will feature:

• Essentials of control valves
• Actuators and associated valve equipment
• Theoretical and practical sizing aspects
• Selection, installation and maintenance essentials
• Tuning and optimizing a process, using control valves

By the end of this training course, participants should be able to:

• Comprehend valve operation
• Understand and appreciate assorted common valve types
• Size and select the correct valve set (including actuators), suited to each specific application
• Choose suitable positioners, based on prevailing conditions
• Use multiple techniques to tune a valve-controlled process
