صمام كرة عائم مصبوب API مزود بفلانش ومنفاخ مطروق
This product is a API forged bellows floating ball flange ball valve with bellows, installed in industrial pipeline systems to provide rapid on/off and shutoff control while ensuring leak-tight performance. The valve body is made of high-strength materials, combined with an internal bellows sealing structure, effectively preventing leakage and making it suitable for corrosive or high-temperature media in oil, chemical, power, and industrial pipeline systems.
Featuring a full-bore floating ball design, the valve provides smooth flow, low pressure drop, efficient operation, and reliable sealing. The rising stem structure allows the valve position to be visually monitored for convenient on-site operation. Flanged ends are designed with ANSI RF (Raised Face) sealing surfaces, ensuring secure installation and compatibility with standard piping systems. Manual operation offers a simple, user-friendly mechanism with easy maintenance, suitable for long-term service under conventional pressure ratings. This bellows-sealed floating ball valve is widely used in industrial pipelines as a highly reliable switching and isolation device.

الخصائص الهيكلية لـ
A metal bellows seal is applied at the stem area, completely isolating the process medium from the atmosphere and eliminating the risk of stem leakage, ideal for toxic, hazardous, or high-purity media.
The forged steel body ensures high strength, dense material structure, and stable mechanical performance for industrial piping applications.
Line pressure pushes the ball against the downstream seat, providing reliable tight shutoff.
RF flange faces conform to ANSI standards, allowing convenient installation and maintenance.
Opening and closing are achieved by a 90-degree rotation, ensuring fast response and low operating torque.
- Sealing surfaces are protected from direct flow erosion when fully open or closed, reducing wear.
Widely used in petroleum, chemical, pharmaceutical, power, and fine chemical industries where high sealing integrity is required.
