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.

Valves are crucial control components in fluid transport systems, playing an indispensable role in our daily lives, industrial production, oil transportation, and more. Although a valve is just a small component, its function is extremely important.It can perform opening and closing functions, cutting off or connecting the flow of fluid media by fully opening or closing, isolating equipment and pipeline systems; it has a regulating function, adjusting pipeline resistance by changing the valve opening, thereby regulating the fluid’s velocity, pressure, and flow rate; it can control the flow direction, such as check valves preventing fluid backflow, and distribution valves distributing and controlling the flow direction of fluid; it also has a safety protection function, when the pressure in the pipeline or equipment exceeds the specified value, safety valves will automatically release pressure to maintain a certain level and ensure safety.

The double offset butterfly valve achieves a “double eccentric” structure by simultaneously offsetting the valve stem axis from both the butterfly plate center and the valve body center. Compared to center-line butterfly valves, it offers greater pressure resistance, stability, and service life; it also supports metal seats and can operate at temperatures up to 500°C, extending its application to high-temperature conditions. The valve has lower flow resistance, making it particularly suitable for large-diameter water, gas, oil, and corrosive media pipelines (DN200 and above) for regulation or shut-off applications.

The Cryogenic Double Block & Bleed Ball Valves is designed for cryogenic conditions ranging from -196℃ to -46℃ and is widely used in storage and transportation systems for media such as liquefied natural gas (LNG), liquid nitrogen, and liquid oxygen. The valve body is made of cryogenically resistant materials (such as 304L and 316L), and the valve stem is lengthened with a drip tray to prevent cryogenic conduction to the packing. The sealing structure features fireproof, anti-static, and stem blowout prevention designs, ensuring flexible operation and zero leakage in cryogenic environments. It is a core safety component for critical equipment such as LNG receiving stations and air separation units.
