The advantages of flange butterfly valves are:
1. Compact and lightweight, easy to disassemble and maintain, and can also be installed in any position.
2. The structure is simple and compact.
3. The flow characteristics are close to a straight line, and the adjustment performance is very good.
4. The connection between the butterfly plate and the valve stem generally adopts a pin free structure, which overcomes the possibility of internal leakage points.
5. The outer circle of the butterfly plate adopts a spherical shape, greatly improving the sealing performance and extending the service life of the valve.
6. The sealing element can be replaced, and the sealing is reliable and achieves bi-directional sealing.
7. Butterfly plates can be sprayed with coatings according to user requirements.
8. This valve can be designed with two connection methods: flange connection and clamp connection.
9. The driving mode can be selected as manual, electric, or pneumatic.
