Second, the main features of the soft-sealed pneumatic wafer-type butterfly valve:

1. Compact and lightweight, easy to disassemble and repair, and can be installed in any position.

2, the structure is simple, compact, operating torque is small, 90 ° swing open quickly.

3. The flow characteristics are straight and the adjustment performance is good.

4. The connection between the disc and the valve stem adopts a pinless structure, which overcomes the possibility of internal leakage.

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

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

7, the disc can be sprayed according to user requirements, such as nylon or polytetrafluoroethylene.
