COURSE OVERVIEW:

The Control Valve Technology: Selection, Sizing, and Maintenance course is a specialized technical program focused on the most critical final control element in any process loop. The control valve is the "business end" of automation, physically manipulating the process to achieve the desired state. This course provides a comprehensive exploration of valve mechanics, fluid dynamics, and actuation, ensuring that participants can select the right valve for the right application while maintaining its performance over a long operational lifecycle.

The scope of this training addresses the engineering rigor required for accurate valve sizing and selection. Participants will learn how to calculate Flow Coefficients and navigate the complexities of flashing, cavitation, and choked flow in high-pressure drops. The curriculum covers a wide variety of valve architectures, including globe, ball, butterfly, and rotary plug designs, detailing the specific advantages and limitations of each in different process media—from clean liquids to abrasive slurries and corrosive gases.

This coverage also emphasizes the technical aspects of valve automation and maintenance. The course provides a deep dive into the selection of actuators and the configuration of smart digital positioners, which are essential for precision control and remote diagnostics. Attendees will learn systematic maintenance procedures, including packing adjustments, seat leakage testing, and the interpretation of valve signature curves for predictive maintenance. By mastering these skills, participants will be able to minimize process variability, reduce fugitive emissions, and extend the intervals between valve overhauls.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Identify and categorize various control valve types and their specific applications.
• Perform accurate control valve sizing using ISA/IEC 60534 standards.
• Select appropriate valve trim and materials to resist erosion and corrosion.
• Predict and mitigate the effects of Cavitation, Flashing, and Choked Flow.
• Calculate and reduce Aerodynamic and Hydrodynamic Valve Noise.
• Select the correct valve characteristic (Linear, Equal%, Quick Opening) for the loop.
• Specify and size pneumatic actuators for fail-safe and high-thrust requirements.
• Configure and calibrate smart digital positioners for precision control.
• Implement fugitive emission control using advanced packing and bellows seals.
• Perform seat leakage testing according to ANSI/FCI 70-2 standards.
• Troubleshoot valve stiction, hysteresis, and deadband issues.
• Utilize diagnostic software to perform valve signature and step-response analysis.

TARGET AUDIENCE:

This course is intended for Mechanical Engineers, Instrumentation Technicians, Maintenance Supervisors, and Process Engineers involved in the design, procurement, and upkeep of control valves.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
