1. the valve adopts three eccentric sealing structure, the seat and butterfly plate almost no wear, with tighter sealing function.
2. the valve body is made of stainless steel, with the double advantages of metal hard seal and elastic seal, no matter at low temperature and high temperature, has excellent sealing performance, corrosion resistance, long service life and other characteristics.
3. The sealing surface of butterfly plate is surfacing with cobalt-based hard alloy, which is resistant to wear and has a long service life.
4. The large-size butterfly plate adopts the structure of quilting, with high strength, large flow area and small flow resistance.
5. the valve has a two-way sealing function, installation is not limited by the flow direction of media, not affected by the space position, can be installed in any direction.
6. The driving device can be installed in multiple stations (rotating 90° or 180°) for the convenience of users.
