API Forged Floating Ball Internal Thread Ball Valve
This API Forged floating ball internal thread ball valve with female threaded (NPT) connections is forged from A105 carbon steel and is engineered for small to medium-sized industrial pipelines, providing precise flow isolation and system control. The robust body ensures reliable performance under high temperature and standard industrial pressure conditions.
The floating ball mechanism delivers tight sealing while maintaining minimal pressure drop during operation, ensuring consistent flow throughout the system. NPT threaded connections enable compact and space-saving installation while maintaining secure sealing. Manual lever operation allows straightforward on-site control for rapid flow start/stop. This valve is widely used in chemical, oil, power, and general industrial pipelines, serving as an efficient solution for flow control and isolation in confined spaces.

Structural Characteristics of
The forged construction provides dense material structure and high mechanical strength, suitable for Class 800 pressure applications.
Line pressure forces the ball against the downstream seat, ensuring tight shutoff and reliable sealing performance.
Female NPT threads allow quick installation in small-bore piping systems with compact space requirements.
The three-piece body design enables convenient disassembly and seal replacement without removing the entire valve from the pipeline.
A 90° lever rotation provides 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 high-pressure small-bore piping systems handling oil, gas, chemical fluids, steam, water, and general industrial media.
