Trunnion ball valve Vs Floating ball valve
Speciality Valve is a reliable manufacturer of a standard ball valve, including a trunnion ball valve and floating ball valve. Although both industries are widely used in industries, it is important to understand their differences in informed decision -making.
A ball valve is a quarter turn valve that controls flow of liquid or gases using a circular ball with a bore. The rotation of ball with a handle or actuator determines whether valve is open or closed. These valves are known for their dense seals, durability and reliability under high pressure and temperature.
Understand Trunnion ball valve
A trunnion ball valve has a certain ball supported by a shaft in both top and bottom. This design ensures stability, especially in high pressure applications. The trunnion -mounted design reduces the power required to operate the valve, making it ideal for large diameter pipelines.
Working mechanism
In a trunnion ball valve, the ball remains fixed in place by a trunnion, while the seat rings move slightly under fluid pressure. When the valve is in the open position, the flow passes freely through the bore. When the handle or actuator rotates the ball 90 degrees, the port aligns perpendicular to the pipeline, stopping the flow completely. The additional mechanical anchoring reduces the load on the seats, making operation smooth and efficient.
Key Components of Trunnion Ball Valve:
- Ball: Fixed in place by trunnion support.
- Trunnion: Provides additional stability to the ball.
- Seats: Move slightly to ensure a tight seal.
- Stem: Connects to the actuator or handle for operation.
- Body: Houses all internal components and withstands pressure.
- Seals and Gaskets: Prevent leakage and enhance durability.
Important features of trunnion ball valve:
- Fixed ball support: The ball is led by a trunnion, which reduces the movement under pressure.
- Lower operating moments: Low force is required to function due to extra support.
- High pressure performance: Suitable for extreme pressure conditions.
- Double sealing system: Provide a tight shutdown to prevent leakage.
- Available in large sizes: Usually used in industrial applications where large flow capacity is needed.
Application of trunnion ball valve:
- Oil and gas industry: Used in upstream, midstream and downstream applications.
- Petrochemical plants: handle invasive chemicals and high pressure.
- Power plant: Steam and other high temperatures control fluid.
- Water Treatment Plants: Used in large pipelines requiring robust sealing.
Understanding Floating Ball Valve
A floating ball valve consists of a ball that is not determined by a trunnion but held in place by valve seats. This design lets the ball swim a little, which helps to create a tight seal against the downstream seat when the pressure is applied.
Working mechanism
In a floating ball valve, the ball valve is free to move slightly into the body. When the valve is closed, pushing upstream pushes the ball towards the downstream seat and makes a tight seal. This liquid action also ensures effective sealing in low -pressure applications. When the valve opens, the ball rotates to coordinate with the flow, allowing an uninterrupted passage of liquid.
Key Components of Floating Ball Valve:
- Ball: Free-floating to press against the seat under pressure.
- Seats: Create a seal when pressure is applied.
- Stem: Controls the ball’s movement through a handle or actuator.
- Body: Encases all components and withstands external conditions.
- Seals and Gaskets: Prevent leakage and enhance durability.
Important features of trunnion ball valve:
- Floating Ball Design: The ball moves slightly to press against the downstream seat.
- Compact and light: Typically smaller and lighter than trunnion ball valves.
- Cost effective: Simple design and cheaper due to low components.
- High torque requirements: More power is needed to function due to trunnion deficiency.
- Limited to Medium Pressure Applications: Best suited for low to medium pressure systems.
Applications of Floating Ball Valve:
- Chemical Processing: Handles a variety of liquids and gases.
- Water and Wastewater Management: Used in piping systems for fluid control.
- HVAC Systems: Regulates cooling and heating fluids.
- General Industrial Use: Ideal for light to medium-duty applications.
Trunnion ball valve Vs Floating ball valve
| Feature | Trunnion Ball Valve | Floating Ball Valve |
| Ball Support | Fixed by a trunnion | Free-floating |
| Operating Torque | Lower due to support | Higher due to friction |
| Pressure Handling | High-pressure systems | Low to medium pressure |
| Size Availability | Large diameter pipelines | Smaller applications |
| Sealing Mechanism | Dual sealing system | Single sealing seat |
| Cost | Higher due to complex design | More affordable |
Select the Right Ball Valve for your application
When choosing a ball valve, consider the following factors:
- Pressure requirements: If you handle high -pressure applications, a trunnion ball valve is ideal.
- Size ideas: For pipelines with large diameter, trunnion-mounted valves provide better support.
- Budget deficiency: If costs are a concern, floating ball valves give a reasonable solution.
- Operation: If the operation requires easy operation, the trunnion ball valve requires less effort to operate.
- Application type: For industries such as oil and gas, a trunnion ball valve is recommended, while for general industrial use a floating ball valve is sufficient.
