What valves can be used to manually adjust flow rate
Thread Content
For liquid media, which valves provide the best control performance? Some butterfly valves in our factory are used to regulate flow, and over time they stop sealing properly.
Globe valves are suitable for manually adjusting flow, but it is difficult to operate globe valves with a diameter larger than DN200.
There are dedicated manual throttle valves for adjustment
Poster: For large sizes, it is recommended to use a plug
For small diameters, stop valves are used; for larger diameters, plug valves are employed. Of course, if the operators are skilled enough, butterfly valves can also be used
Gate valves and plug valves might work a bit better
Gate valves are more commonly used, while butterfly valves are generally not used for regulating flow!
Dalian-style manual control valves can also be used
