GB Forged Floating Ball Welded Ball Valve
This product is a GB forged floating ball welded ball valve, installed in pipeline systems to provide rapid on/off and shutoff control, widely applied in oil, chemical, power, and industrial pipeline networks. The body is made of F304 stainless steel, offering excellent corrosion resistance and mechanical strength, suitable for high-temperature, high-pressure, and various industrial media environments.
The valve features a full-bore floating ball design, ensuring smooth flow, low pressure drop, quick operation, and tight sealing to prevent leakage. The rising stem structure allows the opening position to be visually monitored for convenient on-site operation. Butt-weld ends provide a secure connection to the pipeline system, suitable for high-pressure service conditions. Manual operation ensures a simple and user-friendly design with low maintenance requirements. This floating ball butt-weld valve is widely used in industrial pipelines for flow control and critical equipment protection, serving as an essential component for safe and reliable system operation.

Structural Characteristics of
The valve body is manufactured from forged stainless steel, providing dense structure and superior pressure resistance compared with cast construction, suitable for high-pressure piping systems.
Full-bore passage minimizes turbulence and pressure drop, ensuring efficient flow performance.
Line pressure pushes the ball against the downstream seat, achieving reliable bidirectional sealing performance.
Direct welding to the pipeline eliminates flange sealing surfaces and reduces potential leakage points, ideal for high-temperature, high-pressure, or hazardous media systems.
A 90-degree rotation enables fast opening and closing with low operating torque.
- Sealing surfaces are protected from direct flow erosion when fully open or closed, reducing wear.
- Suitable for water, steam, oil, gas, and corrosive media, widely used in petroleum, chemical, power, and industrial plants.
