Oil and Gas Engineering Training Courses


Control Valves & Actuators - Control & Safety Systems

Introduction:

This training seminar is a highly interactive introduction to the most important features and characteristics of control valves and actuators. Valve and actuator combinations are used in every process around the world, and understanding and utilizing them correctly is essential for efficient operation and control. This training seminar is designed to provide hands-on thinking about valve and actuator installations, enabling participants to consider, select, and install the best equipment for the application at hand.
This Control Valves & Actuators Training Seminar will highlight important aspects of valves and actuators, leading to a better understanding of the flow aspects associated with these devices. The differences between valves and actuators can be very large or very subtle. Participants will learn to note and distinguish the differences between the various devices and how they fit into the larger scheme of things. With this experience, participants will be better equipped to make informed decisions and to help make decisions at a higher level.

Targeted Groups:

  • Key instrumentation personnel involved in valve maintenance
  • Senior management and staff responsible for valve and actuator selection
  • Mechanical and electrical staff that come into contact with valves
  • Process control engineers requiring a high plant availability, often affected by valves
  • Designers, industrial engineers and staff responsible for plant safety
  • All personnel with a vested interest in applications that require / utilize valves

Course Objectives:
At the end of this course the participants will be able to:

  • Comprehend the inner operation of most commonly utilized valve types
  • Decide on the best valve to use, for specific applications
  • Determine the most cost effective valve size
