Valve & Control Valve Masterclass: Design Selection & Sizing

What Will You 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)
