When large diameters and high pressure differences are involved, and globe valves and butterfly valves are no longer suitable, what type of control valve should be used?
Thread Content
May I ask, what type of control valve should be chosen when large-diameter valves with high pressure differences, as well as globe and butterfly valves, are no longer suitable?
What is the caliber? Temperature? Pressure? Differential pressure? Wait
There are no specific parameters; it’s a question posed to me by my supervisor. Based on conventional selection practices, due to the large diameter and high pressure difference, globe valves cannot be used. After butterfly valves, what type of valve should generally be considered?
Parallel double-plate gate valves can be considered
Ball valves will work as well; for valves that need to withstand high pressures, angle valves are sufficient
Sleeve valves should also be an option. It can still meet the requirements for high pressure difference regulation.
This situation should not be common; the process still has some degree of rationality. For smaller pipe diameters, ball valves, corner valves, etc. can be used.
