Description
This course is for engineers, valve mechanics, maintenance personnel, instrument technicians and other persons responsible for the selection, sizing, installation, commissioning, operation and maintenance of control valves, actuators and positioners. The course begins with a review of the role and function of control valves and actuators and offers a technical perspective for the working 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 stem and rotary / fast opening, linear and equal percentage)mixing and diverting 3-port control valvesdiaphragm actuators (air-to-push-up and air-to-push-down)piston actuators (single acting and double acting / Fail Open (FO) and Fail Close (FC))rack and pinion actuators (single acting and double acting / Fail Open (FO) and Fail Close (FC))scotch yoke actuators (single acting and double acting / Fail Open (FO) and Fail Close (FC))pneumatic positioners (force balance, motion balance)digital positionersI/P convertersThe course then proceeds through a series of process examples and solved problems that require you to: dismantle and assemble various types of control valves and actuators using 3D and 2D modelsidentify the net effect of various control valve/actuator assemblies (direct acting, reverse acting, fail open, fail close...)convert an actuator from single acting to double acting configurationconvert a control valve/actuator assembly from a fail close to a fail open configurationconstruct the installation curve for a control valvedetermine flowrate and pressure drop through control valves for different valve liftsmatch the valve characteristics to the given applicationexamine the effect of selecting a control valve larger than necessaryexamine the effect of differential pressure on the valve lift and actuator operationdetermine when a positioner should be fitted... This will help you develop the necessary skills to ensure your process plant and piping systems run smoothly. The course also includes: extensive graphicscross-sectional views3D animationsThis will give you a virtual practical exposure on control valves, actuators and positioners. In addition, we have included at the end of the course a technical quiz (190+ questions) to help you test your knowledge and emphasize the key learning points. The quiz includes: True/False questionsMulti-choice questionsImages, cross-sectional viewsSolved problemsand much more... So when you think you've got a good grasp on a topic within the course, you can test your knowledge by taking the quiz. If you pass, wonderful! If not, you can review 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 training, you can watch it easily, without pain, but with comprehension, and that after completing it, you won't be an experienced process control engineer or instrument technician but you will be prepared to become one if that is what you like and persist to be. Thank you again for your interest in our online courses. It is a privilege to serve you and make sure that you're learning valuable information with us. WR TrainingSpread the wings of your knowledge
