This valve is specially designed for cryogenic environments. The surface of the ball is specially treated to ensure stable and reliable performance even under extremely low temperatures. It is primarily used in pipelines to shut off media containing solid particles, slag, or similar substances under cryogenic conditions. With a simple 90-degree rotation and minimal operating torque, tight shutoff can be easily achieved.
Depending on the selected valve body material, the product is suitable for various media including water, steam, oil, nitric acid, acetic acid, urea, and more. It is widely used in industries such as coal chemical processing, polysilicon production, petroleum, chemical engineering, electric power, and metallurgy.
For ball valves operating at temperatures below -50°C, the neck extension length T is typically 250 mm, or can be determined based on our company's design and calculation standards.
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.
