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

2. Simple and compact structure, small operating torque, and quick 90 ° rotation opening.

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

4. The connection between the butterfly plate and the valve rod 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. Zero leakage is still maintained after more than 50000 times of opening and closing under pressure.

6. The sealing element can be replaced, and the sealing is reliable to achieve two-way sealing.

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

8. The valve can be designed as flange connection and wafer connection.

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