It gets its name from the butterfly-shaped disc inside the valve that rotates to open or close the flow. When the valve is fully open, the disc is positioned parallel to the flow direction, allowing unobstructed passage of water. When the valve is closed, the disc is turned perpendicular to the flow, effectively blocking the flow of water. Water butterfly valves are commonly used in various industries and applications, including water treatment plants, sewage systems, irrigation systems, and industrial processes. They are known for their compact design, lightweight construction, and ease of installation. These valves are often preferred for their quick operation, as the disc can be opened or closed with a simple quarter-turn motion. Butterfly valves can be operated manually with a handle or lever, or they can be automated using electric, pneumatic, or hydraulic actuators to control the valve remotely. They are known for their low-pressure drop and relatively low cost compared to other types of valves. It's worth noting that water butterfly valves are specifically designed for use with water and compatible fluids. Different materials and designs may be required for valves intended for use with corrosive or high-pressure fluids. It's important to select the appropriate type of butterfly valve based on the specific application and fluid requirements.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e
