Course Description:

This course provides the participants with the means to properly operate and support various types of control valve and the differences between them from design, utilization and operation (start-up & shut-down) points of view in a way based on the good acquaintance with the modern technologies applied in this field. Trouble-shooting & forecasting break downs are inclusive

Course Goal:

To enhance the participants’ knowledge, skills, and abilities necessary to understand various types of control valve and the differences between them from design, utilization and operation (start-up & shut-down) points of view
