Course Summary

Control Valves, Actuators & Positioners Course: Operation & Design. Course in Control Valves, Actuators and Positioners: Operation and Design. This course is for engineers, valve mechanics, maintenance personnel, instrument technicians, and others responsible for selecting, sizing, installing, commissioning, operating, and maintaining control valves, actuators, and positioners. This course begins by examining the role and function of control valves and actuators and provides a technical perspective on the operation of positioners for control valve operation. You will find valuable insights into the working principles and construction details of the following equipment: Control valves (sliding and rotating stem / quick opening, linear and equal percentage) Mixing and diverting 3-port control valves Diaphragm actuator (high pressure air and low pressure air) Piston actuators (single function and double function / Fail Open (FO) and Fail Close (FC)) Rack and pinion actuators (single function and double function / fail open (FO) and fail close (FC)) Scotch Yoke Actuators (Single and Double Action / Fail Open (FO) and Fail Close (FC)) Pneumatic positioners (force balance, motion balance) Digital positioners I/P converters The course then walks you through a series of process examples and solved problems that require you to: Disassembling and assembling all types of control valves and actuators using 3D and 2D models Identify the net effect of different control/actuator valve assemblies (direct action, reverse action, failure open, failure close…) Convert an actuator from a single-acting configuration to a double-acting configuration Convert a control/actuator valve assembly from a close-break to an open-break configuration Construct a fitting curve for a control valve Determination of flow rate and pressure drop through control valves for different valve lifters Match the characteristics of the valve to the given application Investigating the effect of choosing a control valve larger than necessary Investigating the effect of differential pressure on valve lift and actuator performance Determine when a positioner should be installed … It will help you develop the skills necessary to ensure the smooth operation of your process plant and piping systems. This course also includes: Extensive graphics Sectional views 3D animations This gives you a virtual hands-on exposure to control valves, actuators and positioners. So when you think you have a good understanding of a topic in the course, you can test your knowledge by taking a quiz. If you pass, that’s great! If not, you can go through the videos and notes again or ask us for help in the Q&A section. We promise you that even though this is a technical tutorial, you will be able to watch it easily, painlessly, but with understanding, and after completing it, you will not be a process control engineer or an experienced instrument technician. But you will be ready to become one if that is what you love and continue to be. Thank you again for your interest in our online courses. It is an honor to serve you and make sure you learn valuable information with us.
