API Forged Floating Ball Flange Ball Valve

API Forged Floating Ball Flange Ball Valve

This product is a API forged floating ball flange ball valve, installed in industrial pipeline systems to provide rapid on/off and shutoff control. The body is made of A105 carbon steel, offering high mechanical strength and pressure resistance for oil, chemical, power, and other industrial media applications.

Featuring a full-bore floating ball design, the valve ensures smooth flow, low pressure drop, efficient operation, and tight sealing, suitable for bidirectional shutoff service. The rising stem structure allows the opening position to be visually monitored for convenient on-site operation. Flanged ends are designed with ANSI RF (Raised Face) sealing surfaces, ensuring reliable installation and sealing, compatible with standard piping systems. Manual operation offers a simple, user-friendly design and easy maintenance, suitable for long-term service under conventional pressure ratings. This floating ball valve is widely used in industrial pipelines as a dependable switching and isolation device.

Structural Characteristics of

  • The valve body is made of ASTM A105 forged steel, providing dense structure and excellent mechanical properties for medium to high-pressure piping systems.

  • Full bore design minimizes turbulence and pressure drop, improving system efficiency.

  • Line pressure forces the ball against the downstream seat, ensuring reliable bidirectional tight shutoff.

  • RF flange faces conform to ANSI B16.5, allowing convenient installation and maintenance in standard industrial piping.

  • Opening and closing are achieved with a 90° turn. The lever operation is easy and can be adapted to pneumatic or electric actuation.

  • Sealing faces are protected from direct flow erosion when fully open or closed, extending service life.

  • Suitable for water, steam, oil, gas, and general industrial fluids, widely used in petroleum, chemical, and power industries.
