COURSE OVERVIEW:

The seamless operation of industrial processes depends on the precise interface between electrical control signals and mechanical fluid regulation. This course provides a technical framework for the "Sizing and Selection" of control valves, focusing on the critical collaboration required between electrical, instrumentation, and control engineering teams. Participants will explore the mechanics of "Valve Trim" and "Actuation," learning how to translate process requirements into electrical specifications for positioners, solenoids, and smart actuators.

The scope of this training addresses the full spectrum of valve types, including globe, butterfly, and ball valves, and their specific "Flow Characteristics." It covers the technical nuances of "Sizing Calculations”, focusing on the prevention of "Cavitation," "Flashing," and "Choked Flow" through correct selection. The curriculum provides a detailed focus on "Digital Valve Positioners," ensuring that participants can calibrate and troubleshoot 4-20 mA and HART-based feedback loops that are essential for precise process automation.

Coverage includes the implementation of "Fail-Safe" logic and "Emergency Shutdown" (ESD) valve requirements. Attendees will learn to manage "Electrical Area Classification" for valve accessories, troubleshoot "Hunting" and "Stiction" in control loops, and utilize "Diagnostic Software" to evaluate valve health without process interruption. By bridging the gap between mechanical fluid dynamics and electrical control, the course equips professionals with the expertise required to optimize valve performance and plant reliability.

COURSE OBJECTIVES:

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

• Define the "Anatomy of a Control Valve" and its core components.
• Identify the primary "Valve Types" and their application limits.
• Calculate "Flow Coefficients" for liquid and gas services.
• Select appropriate "Flow Characteristics" (Linear, Equal %, Quick Opening).
• Evaluate "Actuator Types" (Pneumatic, Electric, Hydraulic) and sizing.
• Configure "Digital Valve Positioners" and 4-20 mA control loops.
• Troubleshoot "Stiction," "Deadband," and "Hunting" in valve response.
• Implement "Fail-Safe" modes (Fail-Open, Fail-Closed, Fail-Last).
• Identify "Cavitation" and "Flashing" through noise and vibration analysis.
• Utilize "HART" and "Foundation Fieldbus" for valve diagnostics.
• Manage "Material Selection" for corrosive and erosive environments.
• Document "Valve Data Sheets" and procurement specifications.

TARGET AUDIENCE:

This course is intended for Control Systems Engineers, Electrical and Instrumentation (E&I) Technicians, Maintenance Engineers, and Process Engineers.

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.
