Introduction Of Ball Valve - Advantages, Disadvantages, And Applications

A valve that controls that flow of gas or liquid using a rotary ball which has a bore is known as a ball valve. The medium can flow through or is blocked by rotating the ball a quarter-turn around the axis. As the name of the valve suggests, the complete flow of substances from one opening to the next is controlled by the ball. This work by allowing the hole to be open or blocked the flow of gas or liquid or partially open to regulate the flow. They are very easy to operate and repair because of its simple structure. The ball valve manufacturers designed it with special measures that allow only 90-degree rotation which uses for opening and closing of the valve. Because of ball valve reliability and air-tight sealing when close, it is a notable industrial choice.

Advantages:

  • The ball valve contains a compact and low-maintenance design that does not require lubrication
  • Among all types of valves, this ball valve is cost-effective and smaller in size as well.
  • It has poor throttling characteristics which cause the seat of the ball valve to erode easily.
  • The ball-valve provides leak-proof service.
  • They have multi-way design flexibility.
  • It is durable, easy to use as the opening and closing are quick.
  • It ensures a very tight seal without any need of high torque forces
  • The ball valve of high quality provides reliable service in high pressure and high-temperature applications
  • The multi-port design of ball valve design offers versatility, also reduces the number of valves required.

Disadvantage:

  • The ball valve is not suitable for sustained throttling applications.
  • The suspended particles in slurry or other applications can settle and become trapped in cavities cause leakage, or valve failure.

Applications of ball valve:

  • This type of valve is used for flow and pressure control and it is hut off for corrosive fluids, slurries, and other normal liquids and gases.
  • They are significantly used in natural gas and oil industries. Moreover, also find in many manufacturing sectors, in chemical storage and great also find in residential uses.
  • It is used in the cooling and water supply system.
