Structure specification:
1. Product structure is reasonable, reliable seal, high performance, attractive appearance.
2. Sealing surface CO-based alloy, good wear resistance, corrosion resistance, abrasion resistance, long service life
3. Stem hardening and tempering and surface nitriding treatment, good corrosion resistance and anti-friction properties
4. Double seal, more reliable performance
5. Stem lifting position indicator
6. Parts materials, flange and welding dimensions can be based on the actual working conditions or user requirements reasonable matching, to meet a variety of conditions
