Features
1. Floating Ball Design
The ball is not fixed to any shaft and is allowed to float within the valve body. The ball is held in place by the valve seats and the fluid pressure.
2. Self-Sealing Mechanism
The floating ball is pressed against the downstream seat by the pressure of the fluid, creating a tight seal. This ensures reliable sealing performance.
3. Simple Construction
The design is relatively simple compared to trunnion mounted ball valves, which makes floating ball valves easier to maintain and cost-effective.
4. Bidirectional Sealing
Floating ball valves can provide sealing in both directions, allowing for versatile installation and operation.
5. Size and Pressure Range
Typically used in smaller diameters (usually up to 12 inches) and moderate pressure applications. For high-pressure applications, trunnion mounted ball valves are more suitable.
6. Ease of Operation
These valves require low torque to operate, making them easy to open and close, often using manual levers, gears, or actuators.
7. Compact and Lightweight
Floating ball valves are generally more compact and lighter compared to trunnion mounted ball valves, which can be advantageous in applications with space constraints.
8. Fire-Safe Design
Many floating ball valves are designed to be fire-safe, providing additional safety in case of a fire by maintaining sealing integrity.
9. Anti-Static Devices
To prevent static electricity buildup and potential sparking, floating ball valves often include anti-static devices, which are essential in handling flammable fluids.
10. Versatility
Suitable for a wide range of fluids, including gases, liquids, and slurries, in various industries like water treatment, chemical processing, and general industrial use.
11. Cost-Effective
Due to their simpler design and construction, floating ball valves are generally less expensive than trunnion mounted ball valves, making them a cost-effective option for many applications.
These features make floating ball valves a popular choice for a variety of applications where moderate pressure and reliable sealing are required.
Application
1. Oil and Gas Industry
- Upstream: Used in drilling operations, production manifolds, and wellhead equipment.

Employed in large-scale water treatment plants and distribution systems for their durability and ability to handle high pressures.
5. Marine and Offshore Applications
Suitable for subsea applications and offshore platforms where reliability under extreme conditions is essential.
6. LNG and Cryogenics
Used in liquefied natural gas (LNG) plants and cryogenic processes due to their ability to perform well at low temperatures.
7. Mining and Minerals Processing
Applied in slurry handling, ore processing, and other high-abrasion environments.
8. Pulp and Paper Industry
Used in the processing and transport of pulp and paper products, where large volumes and high pressures are common.
9. HVAC Systems
Utilized in heating, ventilation, and air conditioning systems for large buildings and industrial complexes.
10. Industrial Manufacturing
Used in various manufacturing processes where reliable fluid control is necessary.
11. Chemical Processing
Employed in the handling of corrosive and hazardous chemicals where high integrity and reliability are needed.
12. Fire Safety Systems
Often integrated into fire suppression systems, especially in industrial settings, due to their fire-safe design.
Technical Drawing
Frequently Asked Questions
What is a floating ball valve?
A floating ball valve is a valve where the ball inside is not fixed to a shaft and is free to float within the valve body. It is held in place by the valve seats and seals tightly when pushed against the downstream seat by fluid pressure.
What standards does this specific floating ball valve comply with?
It complies with design standard API6D, face-to-face (FTF) dimension standard ASME B16.10, flange dimension standard ASME B16.5, and test standard API598.
What are the size and pressure ratings for this valve?
This specific floating ball valve has a size of 2 inches (2") and a pressure rating of 150LB.
Does this floating ball valve support bidirectional sealing?
Yes, floating ball valves provide bidirectional sealing, which allows them to seal effectively in both flow directions and offers more versatility during installation.
Why are floating ball valves considered cost-effective?
Because of their relatively simple design and construction compared to trunnion mounted ball valves. They are easier to manufacture, require less maintenance, and are generally lighter and more compact.
