Valve and actuator technology is an essential component of many industrial processes. Whether it is controlling the flow of liquids or gases, these components play a critical role in ensuring that everything runs smoothly. However, for many people, the world of valve and actuator technology can be mysterious and confusing. That is why Newage Learning has developed a training course to help remove the mystery and enhance delegates’ knowledge of these critical components.


The primary goal of the valve and actuator technology training course offered by Newage Learning is to assist delegates in enhancing their knowledge of these components. This training course is designed for anyone who works in industries that use valves and actuators, including but not limited to, oil and gas, power generation, water treatment, and chemical processing.


Correct product selection is crucial when it comes to valve and actuator technology. Choosing the wrong component can result in costly downtime, damage to equipment, or even safety hazards. Therefore, this training course aims to help delegates understand the different types of valves and actuators available and how to select the correct one for their application.


The valve and actuator technology training course offered by Newage Learning covers a range of topics, including:


Valve Overview


This module provides an overview of valve technology, including the different types of valves available, their functions, and common applications. It also covers the advantages and disadvantages of an assortment of different types of valves used in industries.


Valve Types, Associated Equipment and Characteristics


Valves are devices used to control the flow of fluids (liquids, gases, or slurries) by opening, closing, or partially obstructing the flow path. There are several types of valves available, each with its own unique characteristics and associated equipment. This module provides a contrast between the inherent and installed characteristics of valves and actuators. It also covers the pros and cons of an assortment of different types of valves, the list includes:

  • Butterfly
  • Ball
  • Rotary plug
  • Diaphragm
  • Bellow sealed (both forged and welded)
  • Breathe/Vacuum Release
  • Orbit
  • Pressure Seal
  • Fixed Cone and Annular Valves


Manual and Software Valve Sizing, Actuators and Positioners, Trims and Maintenance


Manual valve sizing involves selecting a valve based on the required flow rate, pressure, and temperature of the fluid being controlled where as Software valve sizing involves using specialized computer programs to calculate the required valve size based on specific system parameters such as fluid properties, flow rates, and pressure drops. Actuators are devices that convert energy into motion to open or close a valve. There are several types of actuators including pneumatic, hydraulic, and electric. Positioners are devices that ensure accurate control of the valve position by providing feedback to the actuator. Valve trim refers to the internal components of the valve that come into contact with the fluid being controlled. These components include the disc, seat, stem, and other related parts.


Proper maintenance of valves is essential to ensure they continue to function correctly and efficiently. Maintenance tasks may include regular inspection, cleaning, and lubrication of valve components, as well as the replacement of worn or damaged parts. It is important to follow the manufacturer’s recommended maintenance schedule to ensure safe and reliable valve operation.


Pressure Relief, SIS, Valve Action, Combinations, Terminology, Codes and Standards


Pressure relief valves are safety devices used to protect equipment and piping from overpressure and Safety Instrumented Systems are designed to detect and mitigate hazardous conditions that could lead to accidents or equipment damage. Valve action refers to the direction in which the valve opens or closes. There are several types of valve actions including rising stem, non-rising stem, rotary, and sliding stem. Valves are often combined with other equipment to provide specific functions such as pressure regulation, flow control, and fluid isolation. Examples of valve combinations include control valves with positioners and limit switches, pressure relief valves with rupture discs, and check valves with strainers. Valve terminology includes a range of terms used to describe valve components, functions, and operating characteristics. Some common valve terms include body, bonnet, disc, seat, stem, trim, flow coefficient, and pressure drop. There are several codes and standards that govern the design, installation, and operation of valves and related equipment. These include ANSI, API, ASME, ASTM, ISO, and NACE. Compliance with these standards is essential to ensure safe and reliable valve operation.


Using Control Valves in an Assortment of Control Strategies


Control valves are used in a variety of control strategies to regulate the flow of fluids in process industries. These include on-off, proportional, integral, derivative, and PID control. The valve position is adjusted based on the control algorithm to achieve the desired flow rate and maintain the process variable at a set point.


In conclusion, the Valves & Actuators Technology training course offered by Newage Learning provides a comprehensive overview of valve technology and its applications in various industries. The course covers a range of topics including valve types, sizing, selection, maintenance, and safety. Participants will also gain practical knowledge about valve actuators, positioners, trims, and control strategies. 


With this course, participants can enhance their skills and knowledge to become more effective and efficient in valve-related roles within their organizations. Overall, the Valves & Actuators Technology training course by Newage Learning is a valuable investment for professionals looking to expand their expertise in this field.
