Main structural features:
Main structural features:
- The product structure is reasonable, with the reliable seal, the excellent performance, and the beautiful shape;
- Sealing surface surfacing co-based cemented carbide, wear and corrosion resistance, anti-friction performance, lead to a long service life;
- Stem quenching and nitriding treatment, then it can have good corrosion resistance and anti-friction performance;
- Double seal makes a better reliable performance;
- The stem lift indicates a more intuitive position;
- Parts material, flange and size number of butt welding can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
