What is a ball valve?
A ball valve is a type of shut-off valve that regulates the flow of a liquid or gas using a rotatable ball with a bore. The medium can flow through or is blocked by turning the ball a quarter-turn (90 degrees) around its axis. They have a long service life and offer consistent sealing even when the valve is not in use for an extended period of time.
What is Valve and what are the major types of Valves?
Ball valves are intended for use in a wide range of applications and markets, but a V-port ball valve can also be employed as a control valve when appropriate.
What are the types of ball valves?
Ball valves are mainly classified into six types. They are
- V-Port Ball Valve
- Full Port Ball Valve
- multi-port ball valve
- standard port ball valve
- reduced port ball valve
- True union
- Manually operated ball valve
In this article, we are going to explain V-Port Ball Valves.
What is a V-Port Ball Valves?
A V-Port Ball Valve is distinguished by either a 'v-shaped seat or a ‘v’ shaped ball. This permits the orifice to be opened and closed more precisely, resulting in a more linear flow characteristic. Because flow velocities must be regulated depending on the application, this sort of valve is also known as a control valve.
What is the Working Principle of V-Port Ball valves?
The working principle of a ball valve is that it regulates, directs, or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing numerous passages with a regulating ball with a hole within. To manage flow through it, it employs a hollow, perforated, pivoting ball.
There are no unique laws (such as Newton’s law or the Bernoulli principle) that govern how valves work. It only exerts control by inserting obstructing particles into fluid channels.
How do V-Port Ball Valves Work?
When v-port valves are closed and opening begins, the little end of the ‘v’ opens first. During this stage, this enables steady flow control. Because higher fluid velocities may harm ordinary valves, the design often demands more robust construction. Despite being a control valve, v-port valves are not as precise as a globe valve, pressure regulating valve, balancing valve, or needle valve.
What are the applications of the V-Port Ball valve?
Ball valves are utilised in a wide variety of applications and markets. Transmission and storage, gas processing, and industrial are just a few examples. V-Port Water treatment, food processing, acid transfer, agriculture, bleach chemicals, leaching acid, waste processing, and pharmaceuticals are all popular applications for ball valves.
• Leak-tight valves for shutting down and isolating liquid and gaseous services.
• Shut down valves for the system in the event of an emergency.
• Low differential pressure control valves
• It can control and shut off valves for steam service.
• There are vent and drain valves for liquid and gaseous services.
• Pipeline surge control valves
Advantages and Disadvantages of a ball valve
Advantages of a ball valve
-
High efficiency
-
Cheaper than many other valves available in the market
-
Very high life span
-
Easy to use
-
High durability
-
Maintenance is easy and cheap
Disadvantages of a ball valve
-
Poor throttling characteristics
-
Due to retained suspended particles, ball valves can stick in place and become jammed when used to regulate the improper types of fluids, such as slurries. This can cause the valve to wear out, become damaged, or become stuck.
