1. A full range of valve body forging process, smooth appearance, uniform organization, meet the safety requirements of high temperature and high pressure conditions;
2. Pairing of sealing surface materials, high hardness and poor hardness of the confidential cover; precision grinding, wear resistance and corrosion resistance, effectively prolonging the service life;
3. Adopt self-sealing design to minimize possible leakage points;
4. The surface of the valve stem is hardened to resist scratches and corrosion;
5. Special corrosion-inhibiting packing structure design is adopted, which is resistant to temperature and pressure, no corrosion, and avoids corrosion on the surface of the valve stem;
6. Manual matching and research to ensure that the sealing surface conformity is more than 90%, and zero leakage is achieved.
