Flange butterfly valve main following 8 characteristics:

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

2, simple structure, compact, small operating torque, 90° rotation open quickly.

3, flow characteristics tend to straight line, good regulation performance.

4. The connection between disc and stem adopts no-pin structure, which overcomes the possible internal leakage point.

5. The outer circle of the butterfly plate adopts the spherical shape, which improves the sealing performance and prolongs the service life of the valve. The valve still maintains zero leakage after being opened and closed for more than 50,000 times with pressure.

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

7. The butterfly plate can be sprayed with coating, such as nylon or ptfe.

8, the valve can be designed for flange connection and clamp connection.
