Control valve Repair & Maintennace
Course Description
In most of oil and gas industries, petrochemical refineries, chemical, food industries the control valve play the most important part in controlling fluid flow and safety of process.
The Training Course Will Highlight ?
Training Objective

  • The purpose of this course is to introduce the fundamental principles of the selection and installation the correct valve and to perform all kind of preventive, predicative, and primitive maintenance because it is very critical for the safety of process.
  • The valves are considered the most expensive element in control loop so you can save millions of Dollars if you have the right knowledge and skills to choose best selection, construction, and engineering and to know how to determine static and dynamic parameter by on line diagnostic without shutdown to any process.

Target Audience

This is designed to train new and limited experience technicians, and limited experience engineer.

The program is useful for mechanical, instrument, electrical, chemical and also senior supervisor.

Training Methods
