    Final Control Elements

    Final control elements are devices driven by a controller and are located in process lines. Final control elements change the operating conditions of the process and require energy to operate against the process pressure.  This energy is usually in the form of air pressure, hydraulic pressure or electricity.  There are a great variety of final control elements and accessories that make each one have its own characteristics to adapt to a particular process dynamic.

    This three day course will introduce the participants to final control elements and their requirements to enable them to control a process. Participants will learn about the different types of final control elements, how they are constructed and their common and unique characteristics. Time will also be spent on discussing the various accessories that are available to enhance the operation of the final control element.  The environmental aspects of final control elements will also be discussed.

    Upon completion of this course, participants will have a better understanding of the many types and varieties of final control elements.  The information gained from this course will be used to enhance and expand a technician’s knowledge base through on-the-job training and practical experience at the plant site.

    Day 1

    Introduction to Final Control Elements

    • Final control element overview
    • Final control elements in the control loop
    • Pneumatic, electric and hydraulic principles associated with final control elements

    On day one, participants will get an introduction to final control elements and where they fit in the process management system.   Discussions will include how they operate and why they are an integral part of the control loop.  They will also review and learn about the different types of energy that are available in terms of operation.

    Day 2

    Final Control Elements

    • Components of final control elements
    • Kinds of final control elements
    • Characteristics of final control elements

    On day two, participants will learn about the components that make up the majority of final control elements. With so many different types of process conditions, the participants will gain knowledge in the different kinds of final control elements and their associated specifications.  They will also be exposed to characteristics of final control elements that are both unique and common amongst the group.

    Day 3

    Final Control Element Accessories, Valve Characteristics, and Rangeability

    • Function of positioners in final control elements
    • Control signals for final control elements
    • Accessories available on final control elements
    • Valve process characteristics and rangeability in final control elements
    • Noise control in final control elements

    On day three, participants will learn about the accessories that are available to enhance the operation of the final control element and the control signals that are available to operate them.  Time will be spent on discussing positioning systems for final control elements, especially control valves.  Since the control valve is the most common final control element the participants will be made aware of how it has to adapt to the process dynamics in terms of process characteristics and rangeability.  With the growing concern of environmental noise generated by control valves time will be taken to discuss this issue.

    This course is mainly targeted to instrumentation technicians working in the field as an introduction or a refresher.  The course can be applicable to technicians working in other disciplines, equipment purchasers, procurement and storage personnel, job planners and immediate supervisors.

    Anyone taking this course should have some exposure to an oil and gas facility terminology.
