Structural Features:
1. Shell precision casting and resin sand casting process, smooth appearance and uniform organization; 
2. Pairing of sealing surface materials to ensure high hardness and poor hardness of the sealing surface; precision grinding, wear resistance and corrosion resistance, and effectively prolong the service life;
3. Multi-channel testing such as high-pressure water strength, air tightness test, non-destructive testing, etc. to prevent leakage of the shell;
4. The surface of the valve stem is precisely ground to improve the anti-scratch performance, effectively reduce the opening and closing torque, and the operation is easy;
5. Special corrosion-inhibiting packing structure design is adopted, which is resistant to temperature and pressure, no corrosion, and avoids external leakage.
