1. Reasonable product structure, reliable sealing, excellent performance and beautiful appearance;
2, the surface welding Co base hard alloy, wear resistance, corrosion resistance, abrasion resistance, long service life;
3. Internal pin shaft structure reduces external leakage and ensures reliable use;
4. When the pressure is Class1500LB, the valve cavity adopts self-tightening sealing chair.
The higher the medium pressure is, the better the sealing performance is.
5. The material, flange and butt welding end size of the parts can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
