Butterfly valves are commonly used in industrial applications to regulate the flow of liquids and gases. They are typically used in large pipelines where precision control is not necessary, but quick and reliable shut-off is required. Butterfly valves are also frequently used in applications that require low-pressure drops and flow control. They are known for their compact design, low cost, and ease of installation and maintenance. Some common applications of butterfly valves include water treatment, chemical processing, power generation, and food and beverage production.
