Main Ball Valve Types and Their Uses You Should Know

Ball valves have become essential for controlling fluid flow safely and effectively in residential and various industries. It offers durability and simple usage and is excellent at regulating flow and isolating the flow rate. In this guide, you will learn about the most common variants of ball valves, including their specifications, advantages, and applications. For those of you in the field of plumbing for homes or specialized uses, and everything in between, these valves should help to increase your knowledge of some of the ones you will come in contact with on the job.

A ball valve is one of the rotary valve types, and it is classified according to the movement of the disc in the valve body. Ball valves are characterized by the ball’s position with a spherical bearing, which can control, open, or close the passage of fluids.

What Do You Understand about a Ball Valve?

The ball valve is another rotational valve that operates based on a spherical component with ports at the center of the ball. Larger ‘holes’ will open vertically and parallel to the flow direction, and the fluid will pass through them. The ball turns 90 degrees in this position, interfering with the water stream. Ball valves are popular and have a significantly easy layout experience, guaranteeing their functionality and leakage loss.

  3. The following part of the ball valve’ shows this vital tool. The main components include:
  4. A. Valve Body: The external cover encloses the machine’s Inside components or apparatus.
  5. B. Ball: The ball has a centrally located orifice called the bore, which girds the fluid.
  6. C. Seat: An element essentially made to guarantee that the valve is tightly closed by providing a tight seal.
  7. D. Stem: The round spindle ties the ball to the control or handle.
  8. E. Handle/Actuator: The part used to rotate the ball could allow you to operate the valve quickly, or the mechanism used could be automatic.

  2. Materials of Construction
  3. Ball valves are made from various materials to suit different applications: Ball valves are made from multiple materials to suit different applications:
  4. A. Brass: Created for low to medium-pressure applications, they generally provide good levels of corrosion protection.
  5. B. Stainless Steel: This material is beneficial in high-pressure and temperature conditions and is highly resistant to acidic environments.
  6. C. PVC: PVC is cheaper due to its thinner walls but it only suitable for low-pressure and non-corrosive applications.
  7. D. CPVC: CPVC is similar to PVC but is built to withstand greater temperatures, making it more suited for specific industrial applications.
  8. The most common ball valves are the basic straight-through and the split-body ball valves.
    There are several kinds of ball valves, depending on their application or the environment in which they operate.
  9. a. Floating Ball Valves:
  10. Description: Of them, the floating ball valves are the most widespread. The ball is between two elastomeric seats located in the valve body. All these designs enable the ball to float slightly downstream of the pressure to form a tight seal.
  11. Uses: These valves are standard in many applications, such as the water supply industry, natural gas distribution, and the chemical industry. They are best suited for low—to moderate-pressure and temperature applications.
  12. b. Trunnion Mounted Ball Valves:
  13. Description: Trunnion-mounted ball valves possess other structural support in the upper and lower sections, referred to as trunnions on a ball. This design bears on the ball and lessens the torque needed to rotate the valve, making this suited for pressure and diameter.Uses: Well-known in the context of the oil and gas industry, the valves are designed for high-pressure systems coupled with enormous throughput, so they are common in pipelines, refineries, and similar processes.
  14. c. V-Port Ball Valves:
  15. Description: V-port ball valves have a V-shaped notch on the ball or the seat. These designs provide better flow control characteristics, most importantly, linear flow, and they are recommendable for applications that need constant and smooth flow rates.Uses: These valves are used in chemical processing operations, where accurate fluid flow regulation is paramount. They are also appropriate for use where high velocities and abrasive fluids are likely.
  16. d. Cavity Filled Ball Valves:
  17. Cavity-filled ball valves have a seat design that removes the cavity between the valve body and the substance. This design stops fluid from getting into the valve area, reducing the risk of contamination and corrosion of the valve parts.

    An air compressor is a machine that takes ordinary air and compresses it into a container to create a high-pressure gas. You just have to connect a pipe or hose to the compressor to use this pressurized air to power tools, clean things, or even fill up your tires…

  19. e. Multi-Port Ball Valves:
  20. Multi-port ball valves have more than two ports and are frequently used for manifold operation. Fluid is easily directed with the help of several lines or pathways, so they can be installed in various ways and are suitable for multiple-path pipeline systems. Such valves prove effective in cases where it is required to turn, separate, or mix the fluid’s flow, such as in water treatment systems or utility plant divisions.
  21. f. Full Port Ball Valves:
  22. Full-port ball valves have a bore equal to the pipeline diameter. These pipes can be effectively used in lines that have to deliver a constant supply of products, such as fuel, fire protection, and large organization water supply lines.
  23. g. Reduced Port Ball Valves:
  24. Sealed port ball valves have a minimum port diameter compared to the line size. This design leads to a higher pressure drop. But it is cheaper. It is suitable for use in low-pressure applications. They are often used in buildings, water supply, and other applications that require low-cost, lower-flow applications and are not for industrial uses.
  25. h. Top Entry Ball Valves:
  26. Top-entry ball valves enable observers to view and check the internal parts of the valve from the top of the valve body. This design also allows simple maintenance and repair without removing the valve from the pipeline. It is highly recommended for use where frequent cleaning is necessary, such as in the oil and gas processing sector, utility production plants, and other industries that manufacture chemicals.
  27. i. Manually Operated Ball Valves:
  28. Manual ball valves are operated using a handle or a lever when the control is turned away from the closed position. They have simple controls and do not need extra energy to generate the necessary impulse to perform their functions; this valve is suitable for all applications. These valves are ideal for handling and controlling home water, garden hoses, and minor industries that don’t require automated valve handling.
  29. j. Actuated Ball Valves:
  30. The ball valves are operated and based on electric, pneumatic, and hydraulic actuated valves. These work as actuators and give accurate control. They could also be made responsive for remote control. Such valves are helpful when they must be controlled accurately and automatically without frequent intervention, such as industrial complexes, production lines, and hard-to-access locations.
  31. However, selecting a ball valve depends on the fluid type in the system, the required pressure and temperature ratings, and the application requirements.
