Ceramic Knife Gate Valve
Function and Utility:
1. The valve is used in concentrating mills and coal preparation plants for open-close purposes. Suitable medium: dry ash, ash slag, coal dust.
2. Operating pressure: 1.0MPa - 1.6MPa
3. Operating temperature: not higher than 180°C
Performance Characteristics:
1. This valve is designed for use in high-wear pipelines. It features a compact design, easy installation, and a ceramic composite sealing form (ZTA) on the seal seat. The hardness of the ceramic (HRC ≥ 90) ensures excellent toughness, addressing the issue of brittle ceramics and ensuring high wear resistance and corrosion resistance. The valve plate is made of high chromium alloy, offering high wear resistance, impact resistance, and can be used for throttling. Additionally, it provides smooth operation with minimal friction, preventing ash deposition and clogging within the valve chamber.
2. The valve can be installed horizontally or vertically, but not inversely.
3. Easy installation and robust dimensions.
