API Flanged Floating Ball Valve
The API Flanged Floating Ball Valve is engineered in accordance with international standards such as API 6D and ISO 17292, providing high-performance fluid control solutions for oil & gas, chemical, power, and metallurgical pipeline systems. The valve body is made of forged or cast high-strength steel, offering excellent pressure resistance, corrosion resistance, and high-temperature performance, ensuring long-term reliable operation.
The floating ball design allows the ball to seal against the seats through its floating movement, ensuring bidirectional tight shut-off, smooth operation, and rapid closing. Valve seats are available in reinforced PTFE, metal-to-metal, or composite sealing materials, selectable according to the medium and operating conditions to achieve optimal leakage control. The valve can be equipped with manual, gearbox, or pneumatic/electric actuators, facilitating remote operation and automation integration.
Designed with safety, durability, and ease of maintenance in mind, this valve is suitable for high-pressure pipelines and critical service applications, making it a reliable choice for fluid control in demanding industrial environments.

General introduction to valves
1.Operating:Extended lever for easy operation.Also available with gearing, motoractuator, pneumatic or hydraulicactuators for more difficult services.
2.BODY & BONNET:Split or 3-piece Split body&bonnet for 12″&Small Disassembles easily for repair or replacement of interrnalcomponents.
3.BORE:Full and reduced full diameters are suitable for large flow media,can also be clean the pipe.
4.End Connections:Flange connection, ring connection and butt welding fitting can be used.
5.Packing:STD Packing Multiple V-TETFLON packing, combined with live loading,maintains packing compression under high-cycle and severe service applications.Graphite packing use situation for high-temperature.
- 6.Valve stem anti-detachment(BPS):To prevent stem shedding,a pressure-safe stem design should be designed with a trip-proof design that does not fly out under normal pressure.
- 7.electrostatic spring(AS):This connection always moves between the ball and stem/body and the unloading eventually stops during operation.
- 8.fire signs(FD):Fire Durable. Designed according to API607 or BS6755 to ensure their operability in case of fire. The metal seal surface ACTS as a barrier when the main sealing surface is damaged by fire. and API607 compliant valves with graphite packing and gaskets.
