1. The shell adopts forging and casting process options, with smooth appearance and uniform organization, meeting the requirements of high temperature and high pressure; A full range of full forged steel gate valves can be provided according to user requirements;

2. The matching of special materials ensures the high hardness and poor hardness of the sealing surface; Precision grinding, smooth as a mirror, wear-resistant and corrosion resistant, effectively extending the service life;

3. The back seal design can effectively protect the sealing filler and prevent leakage;

4. High pressure water strength, high pressure gas strength, non-destructive testing and other multiple tests to comprehensively control the quality of pressure parts;

5. The surface of the valve stem is precisely ground and hardened, which is resistant to abrasion and corrosion, effectively reduces the opening and closing torque, and makes operation easier;

6. It is designed with special corrosion inhibiting packing structure, which is resistant to temperature and pressure, non corrosive, and automatically lubricated to reduce the friction between opening and closing, avoid corrosion on the valve stem surface, and thus avoid leakage;

7. The two-way pressure bearing seal design meets the strict requirements of various special working conditions;

8. Strictly carry out manual matching research to ensure that the mating degree of the sealing surfaces on both sides is more than 90%, and achieve bubble level factory sealing detection;

9. Z60 series unique ram elastic groove design can automatically compensate processing errors, adapt to high temperature conditions, and avoid seizure; Z62Y series is designed with double rams. The rams automatically correct processing errors and always maintain 100% coincidence of sealing surfaces, which is especially convenient for users to repair and maintain on site;

10. The valve cover is designed with self tightening seal. The higher the pressure, the more reliable the seal.
