GB кованый шаровой кран с приварным соединением, удлиненной трубой и плавающим шаром

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.

Структурные характеристики

  • 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.
