Valve types on clean water pipelines
Thread Content
Should valves on clean water pipelines be globe valves or butterfly valves?
Butterfly valves are commonly used in large-diameter clean water pipelines, while globe valves are more often used when precise control of water flow is required.
OP, it depends on how thick your pipeline is. If the pipeline is too small, there’s no need to use a butterfly valve; a regular valve will suffice.
The valves used in clean water pipelines depend on the pipe diameter; when the diameter is less than 40, only globe valves or gate valves can be used, as there are no butterfly valves available for diameters below 40； Welding or threading can be used; for pipes with a diameter greater than 40, both methods are applicable.
Butterfly valves are used for large pipelines; they are inexpensive
How much can the price difference be between butterfly valves and gate valves (for the same size)? What is the current market price?:lol
It’s far from enough; just look at the size of the valve body to see that
