1. The valve body thickness exceeds the standard data requirements of national standards GB, JB, and American standard ANSI, with the main material's chemical elements and mechanical properties meeting the national standard requirements. The three-section structure design of the body ensures robustness and an aesthetically pleasing appearance.

2. Valve stem material meets national standard requirements for chemical elements, precision ground, and surface treated with corrosion-resistant nitriding or heat treatment, ensuring excellent mechanical properties and corrosion resistance.

3. Equipped with an internal buffer compensating elastic gasket for stable and excellent sealing. Also, it resists sticking and ball rupture in impure media.

4. The all-rimmed hard seal surface contact ceramic ball valve features structural ceramic materials in all contact with the medium, boasting the chemical stability and hardness (HRA 88 or above, second only to diamond) properties. Consequently, the ceramic exhibits high compressive strength, excellent wear resistance, and superior anti-oxidation and corrosion resistance, as well as high temperature resistance and good thermal insulation properties.

5. Produced with precise grinding technology and advanced machinery, our valves feature a simple structure, smooth flow paths, and minimal resistance to medium flow. The hard seal ceramic inner components consist of six scientifically designed parts, with ball and seat surfaces precision-machined for a tight fit of the ball's internal and external R's, resulting in high ball roundness, excellent surface quality, and low torque and resistance for the entire valve, achieving zero leakage in sealing.
