Product Features

1. The product structure is reasonable, the seal is reliable, the performance is fine, the shape is beautiful;
2. The sealing surface is overlaid with Co based cemented carbide, which has good wear resistance, corrosion resistance, friction resistance and long service life;
3. The valve stem has good anti-corrosion and anti friction properties by quenching and tempering and surface nitriding treatment;
4. Double sealing, more reliable performance;
5. Valve rod lifting position indication, more intuitive;
6. The material and size of flange and butt welding end can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
