UAE Valves is your Trusted Valve Partner and is committed to provide high quality industrial valve that ensure efficiency, durability and safety. While sharing similarities in the function, they are yet different in design, operation and application. Understanding Ball valve and plug valve difference can help industries choose the most appropriate valve for their needs.
It is quarter turn valve that use spherical disc (ball) to control fluid flow. The ball has hole (bore) through its center, which align with pipe when open, allowing fluid to pass through. When turned 90 degrees, the ball blocks the flow completely.
Key Components of Ball Valves:
- Ball: Spherical disc with a bore for fluid passage.
- Stem: Connects the ball to the actuator or handle for rotation.
- Seats: Provide sealing between the ball and valve body.
- Body: Houses all internal components and ensures durability.
Working Mechanism:
A ball valve operates on a quarter-turn rotational motion mechanism. It consists of a hollow, perforated ball that pivots inside the valve body to control fluid flow. The mechanism works as follows:
- Open Position (Fluid Flowing)
- When the valve handle is turned parallel to the pipeline (0° position), the bore (hole in the ball) aligns with the pipe.
- This allows fluid to pass through with minimal resistance.
- Closing Process
- As the handle is rotated 90 degrees, the ball also rotates.
- The bore starts turning perpendicular to the pipeline, gradually restricting the flow.
- Closed Position (Flow Blocked)
- Once the handle reaches a 90-degree position, the solid part of the ball faces the flow path.
- The sealing seats press against the ball, completely blocking fluid movement.
Features of Ball Valves:
- Design: A ball valve consist of rotating ball with central bore, stem, and seat.
- Operation: Use quarter turn mechanism for quick opening and closing.
- Sealing: Provide tight seal due to soft seat made from material like PTFE.
- Material: Accessible in stainless steel, brass, carbon steel & plastic.
- Size and Pressure Rating: Suitable for wide range of size and pressure rating.
Advantages of Ball Valves:
- Excellent sealing capability (zero leakage in soft-seated designs)
- Quick quarter-turn operation
- Minimal pressure drop
- Corrosion and chemical resistance
- Long service life with minimal maintenance
Common Applications:
- Oil and gas pipelines
- Water treatment plants
- Chemical processing industries
- HVAC systems
It is quarter turn valve, but instead of ball, it has cylindrical or tapered plug that rotate to control fluid flow. The plug has one or more hollow passages that allow fluid to pass through when aligned with the pipe.
Key Components of Plug Valves:
- Plug: Cylindrical or tapered component with a passage for flow.
- Stem: Connects the plug to the actuator or handle for rotation.
- Seats: Ensure tight shutoff and reduce leakage.
- Body: Encases internal parts and provides structural support.
Working Mechanism:
A plug valve operates via a quarter-turn rotation of a cylindrical or conical plug with a hole.
- Open Position – The plug’s hole aligns with the flow path, allowing fluid to pass.
- Closing Process – Rotating the handle moves the plug, gradually restricting flow.
- Closed Position – At 90° rotation, the solid part of the plug blocks the flow.
- Throttle Position (if applicable) – Partial rotation regulates flow.
Features of Plug Valves:
- Design: Composed of a cylindrical or conical plug, a body, and a stem.
- Operation: Uses a quarter-turn movement for opening and closing.
- Sealing: Can have metal or soft seats to improve tight sealing.
- Material: Made by cast iron, stainless steel, or ductile iron.
- Size and Pressure: Available in various size, often used in medium pressure application.
Advantages of Plug Valves:
- Simple and compact design
- Easy maintenance and quick operation
- Good shutoff performance
- Suitable for handling slurry and viscous fluids
- Can be used for multi-port applications
Common Applications:
- Oil and gas industries
- Wastewater treatment plants
- Chemical processing
- Slurry and abrasive fluid systems
- Fire protection systems
Key Differences Between Ball Valves and Plug Valves
| Feature | Ball Valve | Plug Valve |
| Design | Uses a spherical ball with a bore | Uses a cylindrical or tapered plug |
| Operation | Quarter-turn rotation | Quarter-turn rotation |
| Sealing Mechanism | Soft seats ensure tight shutoff | Can have soft or metal seats |
| Flow Control | Provides full flow with minimal resistance | Slightly more resistance due to plug shape |
| Maintenance | Low maintenance; long lifespan | Requires regular lubrication and maintenance |
| Applications | Used in high-pressure and clean fluid applications | Ideal for slurry, viscous, and dirty fluids |
| Cost | Generally higher due to sealing efficiency | More cost-effective for certain applications |
