1. Small and light, easy to disassemble and repair, and can be installed in any position.

2. The structure is simple and compact, the operating torque is small, and the 90 ° rotation opens quickly.

3. The flow characteristics tend to be linear and the regulation performance is good.

4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage point.

5. The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. The valve can be opened and closed under pressure for more than 50000 times and still has zero leakage.

6. The sealing element can be replaced, and the sealing is reliable to achieve bidirectional sealing.

7. The butterfly plate can be coated according to the user's requirements, such as nylon or PTFE.

8. The valve can be designed as flange connection and pair clamp connection.

9. The driving mode can be manual, electric or pneumatic.
