GB Forged Floating Ball Butt-Welded Extended Pipe Ball Valve
This product is a GB Forged floating ball butt-welded extended pipe ball valve, installed in industrial pipeline systems to provide rapid on/off and shutoff control. The body is made of A105 carbon steel, offering excellent mechanical strength and pressure resistance for oil, chemical, power, and general industrial media applications.
Featuring a full-bore floating ball design, the valve ensures smooth flow, low pressure drop, efficient operation, and tight sealing, making it ideal for bidirectional shutoff and full-open/full-close applications. The rising stem structure allows the opening position to be visually monitored for convenient on-site operation. The butt-weld extended tube design accommodates different pipe thicknesses and special installation requirements, ensuring secure and flexible connections. Manual operation provides a simple and user-friendly design with easy maintenance, suitable for long-term service under conventional pressure ratings. This floating ball butt-weld extended tube valve is widely used in industrial pipelines as a reliable switching and isolation device.

Structural Characteristics of
The valve is equipped with extended pipe ends, ideal for insulated or underground pipelines, minimizing welding heat impact on sealing components.
Manufactured from A105 forged steel, the dense structure provides excellent pressure resistance and reliability.
Line pressure pushes the ball against the seat, ensuring tight and reliable shutoff.
Direct welding to the pipeline eliminates flange joints and minimizes potential leakage points, suitable for high-temperature and high-pressure service.
Full bore design ensures smooth flow and low pressure drop.
Only a 90-degree turn is required for opening and closing, providing fast and reliable operation with low torque.
Sealing surfaces are protected from direct flow erosion when fully open or closed, reducing wear.
Suitable for water, steam, oil, gas, and general industrial media, widely used in petroleum, chemical, heating, and pipeline systems.
