The three-piece hard seal trunnion ball valve is designed for easy installation and maintenance, ensuring excellent sealing performance and operational reliability. These valves are primarily used in pipelines to block the flow of media containing solid particles, ash, and other substances under high-temperature conditions. Tight sealing can be achieved with a 90-degree rotation and minimal turning torque. Depending on the selected valve body material, they are suitable for various media such as water, steam, oil, nitric acid, acetic acid, and urea. These valves are widely applied in industries including coal chemical engineering, polysilicon production, petroleum, chemical engineering, power generation, and metallurgy.
1. This product series has been certified for TUV API 6FA fire protection.
2. Equipped with a built-in high-temperature two-way seal, ensuring stable operation under high-temperature conditions.
3. The valve seat is paired with a cylindrical spring to balance valve thrust and reduce torque.
4. The ball and seat are paired using a specially designed grinding process, achieving a leakage class of up to VI.
To address the diverse working conditions and requirements of customers, the company offers a range of valve solutions tailored for harsh operating environments. For instance, customizations can be made for different media, including specialized ball valve seats, spraying technologies, and unique materials for the valve body.
