Introduction
This highly interactive 5-day Control Valves & Actuators training seminar highlights the
most important features and characteristics of control valves and actuators. Combinations of
valves and actuators are used in just about every process around the world, and the proper
understanding and utilization of them is crucial to efficient operations and control. This
training seminar has been designed in such a way as to empower delegates to think
practically about valve and actuator installations, in a manner that allows them to consider,
select and install the best piece of equipment for the application at hand.
This Control Valves & Actuators training seminar emphasizes the important aspects of valves
and actuators, and lead to a greater understanding of flow aspects pertinent to these devices.
In some cases, the differences between certain valves and actuators can be quite large, whilst
in others, the variations are very subtle. Delegates are taught to focus and differentiate
between the various devices that are available, and how they fit into the greater scheme of
things. This exposure, most certainly, will promote greater confidence in the ability of
delegates to make informed decisions, as well as to assist in decisions that are made at a
higher level.
Program Objectives:
By the end of this training seminar, participants should 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
Determine the best device to drive and operate an assortment of valves
Get control valves to operate optimally in the field, using an assortment of techniques
