Control Valve Training

 

What are the Goals?

By the end of this  Thanh Phong's  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

Who is this Training Course for?
It is irrelevant whether delegate valve knowledge and experience ranges 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 Thanh Phong's  training course is suitable to 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
