Basically, butterfly valves are similar to ball valves in terms of operation. They are both quarter-turn valves used to stop, regulate, start and throttle flow. Generally speaking, you can use a butterfly valve for handling large volumes of fluid.
Butterfly valves were once used in low-pressure applications that do not require tight shut-off. Flow control is also not necessary for these valves in the past. They were preferred because of their lightweight and space-saving characteristics where systems can also benefit from their low-pressure drops.
With the efforts to improve butterfly valve operation, valve designers have incorporated a number of features to extend its capabilities.
What’s more is the new advent of valve features can accommodate large volumes of gases and slurries. You can even choose from a wide range of valve sizes from small to large valves to suit your application needs.
