What Is Multi Turn Electric butterfly valve？
Multi-turn electric butterfly valves are sophisticated control valves designed to regulate fluid flow within industrial piping systems with precision. Unlike traditional butterfly valves that operate with a quarter-turn motion, these valves employ multiple rotations for opening and closing, providing finer control over flow rates. They feature a disc positioned perpendicularly to the flow when closed and parallel when open, allowing for precise modulation of fluid flow. The integration of an electric actuator enables remote or automated control, making them ideal for applications requiring accurate flow control, such as water treatment plants and chemical processing facilities.

Advantages of butterfly valve:
- It is convenient and quick to open and close, labor saving, low fluid resistance, and can be operated frequently.
- Simple structure, small size and light weight.
- Mud can be transported, with the least accumulation of liquid at the pipe mouth.
- Under low pressure, good sealing can be achieved.
- Good adjustment performance.
