What Will I Learn?

• Understand valves and control valves working principles for successful operation of your plant and piping systems
• Understand valve construction details (bonnet, stem, disk, seat, packing, body, etc)
• Know the characteristics and applications for each valve type (ball, plug, gate, pinch, butterfly, diaphragm, check, needle...)
• Know how to choose the correct valve for a certain application
• Know how to dismantle and assemble all types of valves using 3D and 2D models
• Identify and know the principles of operation of common valve actuators (pneumatic, hydraulic, electrical, etc)
• Understand how single acting and double acting pneumatic actuators work through graphics and 3D animations
• Understand the principle of fail open (FO) and fail close (FC) actuators
• Know how to convert a single acting spring return actuator to a double acting actuator and vice versa
• Know how to convert a fail close actuator to a fail open actuator and vice versa
• Be more innovative in your solutions to valve and control valve problems
• Have an organized approach to the procedure of valve sizing in accordance with the ANSI & ISA recommendations
• Be able to size valves for any flow conditions likely to be found in a process plant
• Have a general notion about the confidence to be placed in the sizing result conclusions
• Understand safety valve manufacturers’ literature better and understand their jargon
• Become more aware of the potential benefits and pitfalls of the currently available safety valve technology
• Understand the concept of "Air-to-push-up" and Air-to-push-down"
• Understand the concept of "direct-acting" and "reverse-acting"
• Know how to convert a fail close actuator to a fail open actuator and vice versa
• Understand the concept of valve flow coefficient "Cv" and familiarize yourself with the various units
• Know how to determine flowrate and pressure drop through control valves for different valve lifts
• Know how to match the valve characteristics to the process
• Know how to construct the installation curve for a given control valve
• Understand the effect of selecting a control valve larger than necessary
• Understand the effect of differential pressure on the valve lift and actuator operation
• Differentiate between fast opening, linear and equal percentage valve characteristics
• Understand how valve positioners operate
• Know the different types of valve positioners (P/P, I/P, force balance, motion balance, digital…)
• Understand when a positioner should be fitted
• Understand the working principles of I/P converters and how they are used in control valves
• Put your knowledge to the test at the end of each section with a valuable technical quiz (500+ questions and solved problems)
• Download our valuable Valve Sizing Excel Spreadsheet (included in this course free of charge)

Requirements

• Some engineering or field knowledge is preferable but not mandatory. All the concepts are explained in depth using an easy to understand language to allow students to build their knowledge from the ground up
• Please note that the mathematics in this course is undemanding. All the work can be done with a hand-held calculator with powers, roots and log functions.
• To further help you in this task, the course is accompanied with a Valve Sizing Spreadsheet. The Valve sizing spreadsheet will help you perform all the calculations that we will discuss further ahead in the course. It has all the sizing equations, numerical constants and other parameters built right into it.
• We assume that Microsoft Excel is installed on your computer and that you have basic knowledge of using Excel.
