Feature:

The main features of flange butterfly valve are:

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

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

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

4. The connection between the butterfly plate and the valve stem adopts a pin-free structure to overcome possible internal leakage points.

5. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and extends the service life of the valve. It can maintain zero leakage after opening and closing under pressure for more than 50,000 times.

6. The seals are replaceable, and the seal is reliable to achieve bidirectional sealing.

7. The butterfly plate can be sprayed with a coating such as nylon or polytetrafluoroethylene according to user requirements.

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

9. The drive mode can be selected as manual, electric or pneumatic.
