Structural features:

1, the whole series of valve body forging process, beautiful appearance, uniform organization, meet the high temperature and high pressure operating safety requirements;

2. The sealing surface is welded with cobalt-based hard alloy to ensure the high hardness and poor hardness of the sealing surface; Precision grinding, wear resistance, corrosion resistance, effectively prolong the service life;

3. Self-sealing design is adopted to reduce leakage points;

4, stem surface hardening treatment, abrasion resistance and corrosion resistance;

5, the use of special corrosion inhibition packing structure design, avoid the valve stem surface corrosion, packing seal reliable;

6, manual matching, to ensure the sealing surface of more than 90% of the coincidence, to achieve zero leakage.
