Advantages and disadvantages of ball valves

Ball Valve plays a vital role in daily life as they are used day to day basis, say it from bicycles or automobiles, jet airplanes or any industry. There are different sizes and shapes of valves and each has various dimensions, functions and applications to it.

The industry has numerous use of the Ball valves and in order to ensure that these valves remains functional during the operation, it is safe to maintain it before it gets corroded away. Regular cleaning and lubrication to ensure the smooth functionality is key to their life span.
These valves are categorized into five general bodies which includes three piece bodies, two piece bodies ,single body top entry, a split body and welded. The following qualities make them an excellent choice for controlling various applications and sometimes they are preferred over any other valves which has less control in the throttling applications.

Advantages Of Ball Valves

  • They provide leak-proof service,
  • Open and close quickly,
  • Compared to gate valves, they have very small dimensions,
  • Compared to gate valves, they are lighter,
  • The multi designed flexibility does not exist in the Gate or Globe valve, and hence it lowers the amount of valves needed,
  • These valves are manufactured in different sizes and shapes providing flexibility in selection,
  • The high quality valves provide safe service under high temperature and high pressure conditions, and
  • Compared to other valves, they are controlled with less force.

The main disadvantages of these valves are as follows:

  • The position of the valve handle is rotated,
  • Could not be used for throttling, and
  • These valves with drive mechanism should be installed upright.

The resilient-seal concentric butterfly valve is a common type of valve where the valve stem axis, the center of the butterfly plate, and the center of the valve body are located on the same axis. It uses elastic materials such as rubber for sealing, and the sealing pressure is generated by the elastic force formed by the interference fit between the butterfly plate and the bushing, achieving bidirectional sealing. This valve has a compact structure, low flow resistance, large flow area, and a near-linear flow characteristic, making it suitable for regulating media flow. The sealing ring is removable and replaceable, adaptable to different media requirements. It is commonly used for pipeline media control and flow regulation in petroleum, chemical, and water supply and drainage industries.

Cryogenic Side Entry Triple Offset Butterfly Valve are high-performance valves adapted to low-temperature environments. Their core design utilizes a triple offset structure: the valve stem axis is offset from both the valve body centerline and the butterfly plate center, and the valve seat sealing surface is inclined to the valve body channel axis, achieving torque sealing. The valve body, valve seat, and butterfly plate are made of special materials resistant to low-temperature impact and corrosion, such as stainless steel and alloy steel.

Metal-seated triple offset butterfly valves are valve components used for on/off control and flow control in pipeline systems. They are mainly used in petroleum, chemical, metallurgical, hydropower, and urban heating industries. They can be used in industrial pipelines with a medium temperature ≤425℃ for regulating flow and cutting off fluid.Structural Features The metal-sealed triple-eccentric butterfly valve employs a triple-eccentric design, where the valve stem axis is offset from both the butterfly plate center and the body center. The valve seat rotation axis and the valve body channel axis form an angular sealing structure. This structure includes three eccentric designs: the axis offset from the valve seat centerline, the axis offset from the pipeline centerline, and the valve seat cone tilt. The valve seat sealing ring is typically composed of a soft T-shaped sealing ring and multiple layers of stainless steel sheets. The valve plate sealing surface is overlaid with a corrosion-resistant alloy to form a slanted conical structure.
