Structural features:

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

2. Matching of sealing surface materials, high hardness and poor hardness of sealing surface; Precision grinding, wear resistance, corrosion resistance, effectively prolong the service life;

3, the use of self-sealing design, the possible leakage point is reduced to the minimum;

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

5, the use of special corrosion inhibition packing structure design, temperature and pressure resistance, no corrosion, avoid the valve stem surface corrosion;

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