Process through special techniques, the globe body and valve seat are applicable especially to high-temperature and the medium containing dusts and solid particles.

1. The compensatory movable valve seat construction designed especially made of metal is of great reliability in its sealing performance.
2. The ball valve series should be applied in accordance to the specific flow direction.
3. Multiple driving devices could be prepared for the series.
