Through this article, we hope to shed some light on the topic by explaining the main types of ball valves and highlighting the diverse range, focusing on specific features and applications. Most ball valves are quite simple by nature, so this is not going to be a heavily detailed guide: just a quick run-through of the various types, from floating ball through to trunnion mounted and everything in between.
When it comes to ball valves, there is a commonly overlooked distinction between full port ball valves and reduced port ball valves. Firstly, a full port ball valve is created with an internal diameter that aligns with the pipeline diameter. For example, a 3/4&#; full port ball valve has the same diameter as a 3/4&#; pipe, ensuring free, unobstructed flow.
Conversely, a reduced port ball valve - commonly known as a standard port ball valve - features a slightly smaller internal diameter, resulting in a more restricted flow. This variance is especially notable in large-scale applications, where the cost-effectiveness of reduced port ball valves can be incredibly beneficial. An 8&#; reduced port ball valve, for example, perfectly mirroring the diameter of a 6&#; pipe, offers a more budget-friendly alternative to a full port valve of the same size, generally speaking.
Ball valves are classified based on their construction into one-piece, two-piece, and three-piece designs, each offering distinct features and suited for various applications. All these types are available in both full port and reduced port configurations.
One-Piece Ball Valves: These valves are known for their compact design and cost-effectiveness. Made from a single piece of material, they encase the ball within, making them ideal for moderate, less demanding applications. However, their singular construction means if maintenance or repair is required, the whole unit often needs replacement.
Two-Piece Ball Valves: Offering a balance between durability and ease of maintenance, two-piece valves consist of two separate sections. This design allows for easier access to internal parts than one-piece valves, making them suitable for a broader range of applications, including both residential and commercial settings.
Three-Piece Ball Valves: Known for their solid construction, three-piece valves feature a centre section that houses the ball, stem, and seat, flanked by two end sections for various connection options (like flange, threaded, or weld). This configuration facilitates not only easier installation but also simpler maintenance and repair in the system. While initially more costly, especially for high-pressure ratings (like # or #), their long-term reliability and ease of servicing can offset the upfront investment compared to lower-rated valves (like 600#).
Each type, from the simple and economical one-piece valve to the versatile two-piece and the highly durable three-piece, offers unique advantages. The choice depends on the specific requirements of the application, considering factors like the need for maintenance, pressure demands, and cost implications.
For future scalability, especially when it comes to automation, selecting ball valves with actuator mounting pads is advisable, similar to how one might consider butterfly valves for their distinct advantages in specific systems. Compliance with the ISO- standard is an important factor, as it ensures uniformity in mounting dimensions across the various ball valve manufacturers. This uniformity enables better integration of automation systems and is a critical consideration for applications requiring advanced flow control.
Recent advancements in ball valve design and materials have greatly improved their functionality in some (but not all) cases. One development worth mentioning is the improvement of the split body design, which provides easier maintenance and inspection while also (more importantly) providing a more secure seal. This design has proven particularly useful in applications where reliability and ease of repair are a priority.
Material innovation - especially the more widespread adoption of stainless steel in many ball valves - could also be described as an improvement. Stainless steel offers superior resistance to corrosion and wear, making it ideal for a wide range of applications, including brutal chemical environments and high-pressure situations (stainless steel high-pressure ball valves, in particular, have proven quite popular in recent years).
The inclusion of stainless steel has also allowed for the production of full-bore ball valves, which are useful in situations that require minimal flow resistance and flow control.
The introduction of an improved oversized ball in many ball valve designs has improved fluid flow control, as they offer better regulation of flow (especially in full port valves), making them more suitable for applications that require precise flow characteristics.
The evolution of floating ball designs has led to a more balanced pressure distribution across the valve, improving its general sealing capability and overall operational life.
Valve bodies in ball valves are engineered to facilitate an even, smooth flow: the idea is to reduce turbulence while minimizing pressure drop across the valve.
Closed position functionality in ball valves is important for effective shut-off applications, as this feature ensures a tight seal when the valve is not in use, therefore preventing leaks and maintaining system integrity. In high-pressure scenarios, the reliability of the closed position mechanism is equally important for safety and operational reliability and consistency.
Floating ball designs have almost revolutionized flow control in how ball valves work. The floating ball, which is held in place by compression of the upstream and downstream seats, is designed to adjust under pressure to provide a more reliable seal. This design is incredibly effective in managing fluid flow in more dynamic conditions, ensuring not only precision but also responsiveness.
The full bore ball valve is a variant of ball valve types and plays an important role in flow control. By providing a pathway with the pipeline, bore ball valves maintain constant flow rates - and that's essential for systems requiring steady fluid movement. This design aspect contributes in no small part to the overall operational quality of the valve.
From the valve body design to the closed position and floating ball mechanisms, each aspect is designed to work in tandem to ensure that ball valves operate with a high level of consistency and reliability.
Moving from the general mechanics of ball valves to more specific designs, let's now focus on trunnion ball valves - a type of valve that uses a solid ball with a supporting trunnion mounted at the bottom and top. This structure is particularly effective for handling higher pressures and larger diameters, as the trunnion bears the pressure load, minimizing stress on the ball and seats.
The main distinction lies in their suitability for different conditions. Floating ball valves, with the ball held in place by the compression of the seats, are ideal for lower pressure and smaller-scale operations. Their simplicity and cost-effectiveness make them a preferred choice in less demanding conditions.
Trunnion valves, however, shine in more challenging environments. Their strong design is tailored for larger sizes and higher-pressure applications, where they maintain reliable performance and long life. The trunnion support reduces the torque required to operate the valve, making it easier to operate under high pressure.
Trunnion valves are often the preferred choice in the oil and gas industry, where high pressure and large pipe diameters are common. Their reliable performance under stress makes them suitable for critical safety applications. Conversely, floating ball valves are commonly used in residential and light commercial applications, where ease of operation and cost are more important than the ability to handle extreme conditions.
Certain features distinguish one type of ball valve from another. Among these are the seating material options and the control mechanisms.
Featuring seats made of materials like PTFE or other soft polymers, these valves are renowned for providing excellent sealing capabilities, particularly in low-pressure applications. Their primary advantage lies in the ability to create a tighter seal compared to metal seats, although they are typically less resistant to high temperatures and abrasive materials.

For higher temperature applications and situations involving abrasive or corrosive fluids, metal seated ball valves are often the better choice. While they may not seal as tightly as their soft-seated counterparts, their ability to work well in harsh conditions makes them an invaluable option.
The operational mechanism of ball valves also varies. Lever-operated ball valves offer a simple quarter-turn function, which is ideal for quick and easy control, typically seen in lower pressure systems. Handwheel-operated valves, on the other hand, are suited for applications requiring more precise control, particularly in high-pressure environments.
These valves are designed with safety in mind, featuring a vent that prevents pressure build-up within the valve, making them an essential choice for certain high-risk applications.

Over 60% of our nation's energy is supplied by oil and gas. This makes it crucial for drillers to have the right equipment to ensure rigs and pipelines continue operating at optimal levels. If an improper valve is put in place, the operation could be slowed or even shut down completely, taking a toll on the overall supply delivered from that location. To help better understand the importance of valves, we&#;ll be taking a closer look at two important types: gate valves and ball valves. Gate Valves Gate valves are suitable for both underground and above ground applications and are designed to operate at either fully open or fully closed capacity. While they are typically installed on pipelines to serve as isolating valves, they should never be used for regulating or control. Gate valves are best used when the minimal amount of pressure loss needs to be applied, as there are no obstructions when it is fully opened and when a free bore is needed. This type of valve is multi-turn, meaning that the operation relies on a threaded stem. The main benefit of this slower operation is a reduction of hydraulic shock caused by fluid changing direction or stopping suddenly. Gate valves can be used in many conditions, including: The movement of wastewater or neutral liquids that are between the temperatures of -20 to +70 degrees Celsius, with a maximum flow velocity of 5 m/s, and a standard pressure differential of 16 bar units. The movement of gases between the temperatures of -20 to +60 degrees Celsius, with a maximum flow velocity of 20 m/s and a pressure difference of 16 bar units. Gate valves can be found in two different types: wedge and parallel. Wedge shapes utilize two inclined seats and an included gate, while parallel types use a flat gate. The main difference lies in the methods of sealing with parallel gates relying on line force to aid in sealing, and wedge gates relying on torque. Overall, gate valve s are some of the most common types to be used, able to offer an easy method of valve sealing that is capable of operating even at high temperatures. Ball Valves Ball valves serve as a good option for shut-off valves. With a quick 90-degree turn, you can easily open and close the valve, reducing both time and the risk of leaking. Ball valves can be found in both full bore and reduced bore varieties, with full bore fitting the diameter of the pipeline, and the reduced bore having a smaller diameter. Full bore ball valves are more highly sought after due in large part to their ability to minimize pressure loss. Ball valves should only be used fully open or fully closed. This type is not recommended for flow regulation, as uneven pressure can cause the valve seat to become malformed over time. If this occurs, the potential for leaks increases. The biggest advantage of using this type of valve is the lowered cost of manufacturing and maintenance. Additionally, they are compact, easy to open and close, and require no lubrication while still maintaining a high level of sealing. Overall, high pressure ball valves are great for applications that require tight and secure shut off capabilities. This can be especially important when working with gases, as any leaks could be potentially hazardous.
