How should I approach the multiple-choice questions about valves?
Thread Content
Which of the following descriptions of valves are incorrect? A. Globe valves are suitable for media such as steam; they are not appropriate for media with high viscosity or those that contain particles prone to settling, nor should they be used as vent valves in low-vacuum systems. B. Ball valves have a simple structure and low fluid resistance, making them suitable for use with media at low temperatures, high pressures, and high viscosities; however, they are not suitable as control valves. C. Check valves are generally suitable for media with high purity levels; they are not appropriate for media containing solid particles. D. Throttle valves are suitable for media at high temperatures and pressures, as well as for fluids where temperature and pressure do not need to be regulated; they are not suitable for media with high viscosity or those containing solid particles. Are there any relevant books or standards that can be consulted? Thank you.
Was this question on the exam this year? I can’t remember
Confirm it’s multiple choice? The result found in the book is d, as stated in the process design manual
I was looking at the Chemical Process Design Manual, 3rd edition, Volume 2, page 4-192
