What you will learn
Understand control valves working principles for successful operation of your plant and piping systems
Understand control valve construction details (bonnet, stem, disc, seat, packing, body, actuator, positioner…)
Identify and know the principles of operation of common control valve actuators (diaphragm, piston, rack and pinion, scotch yoke)
Dismantle and assemble various types of control valves and actuators using 3D and 2D models
Understand how single acting and double acting pneumatic actuators work through graphics and 3D animations
Know how to convert a single acting spring return actuator to a double acting actuator and vice versa
Understand the concept of failure mode in control valves : Fail Open "FO", Fail Closed "FC", Fail As Is "FAI"
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 (190+ questions and solved problems)
