Are you looking to upgrade your valves?
Floating ball valves and trunnion valves are common industrial valves that are necessary to run a successful industrial operation. But many people aren’t sure which one is more suitable for their processes and what the pros and cons are.
If you’re considering a trunnion vs floating ball valve, knowing the key differences is essential. Below, we’ll go over the major differences and help you choose which one is best for you.
Durability
Trunnion and floating ball valves are two of the most commonly used valves in industrial applications. Both have their own unique features and advantages, but when it comes to durability, they differ in several aspects.
Trunnion ball valves have a fixed, lower stem that supports the ball and prevents it from shifting during operation. This results in better durability and longer service life.
On the other hand, floating ball valves have a top-mounted stem that allows the ball to move slightly under pressure, which can cause wear and tear over time.
However, floating ball valves are relatively easier and cheaper to maintain and repair compared to trunnion ball valves. Ultimately, the choice between the two uses for valves depends on the specific needs of the application and the level of durability required.
Cost
When it comes to choosing between trunnion and floating ball valves, cost is an important factor to consider. Trunnion ball valves are generally more expensive due to their complex design and construction.
They also require more maintenance, which can add to the overall cost over time. On the other hand, floating ball valves are simpler in design and typically have a lower upfront cost.
However, they may require more frequent replacements due to wear and tear, which can add up in the long run. In terms of cost, trunnion ball valves may be a better option for high-pressure and temperature applications, while floating ball valves may be more cost-effective for lower-pressure and temperature environments.
DHV Industries, a leading valve manufacturer, offers both types of valves to cater to the diverse needs of their customers.
Maintenance
Trunnion and floating ball valves are two popular types of valves used in various industrial and commercial applications. Both have their own advantages and disadvantages, especially when it comes to maintenance.
Trunnion valves are designed with a fixed ball that rotates within two seats, held in place by trunnion bearings. This design requires regular lubrication and maintenance to keep the ball running smoothly.
On the other hand, floating ball valves have a ball that is not fixed, allowing for self-alignment and reduced seat wear. However, the floating design can be more prone to leakage and may require regular seat replacements. Ultimately, the choice between trunnion and floating ball valves will depend on the specific maintenance needs of the application.
Reliability
When it comes to reliability, both have their own advantages and disadvantages. Trunnion ball valves have a fixed ball that is held in place by two bearings, providing stability and preventing ball movement.
This makes them more reliable in high-pressure and high-temperature environments. On the other hand, floating ball valves have a ball that is free to move, which can result in potential leakage.
However, they are easier to maintain and repair, making them more cost-effective in the long run. Ultimately, the choice between trunnion and floating ball valves for reliability will depend on the specific needs and conditions of the project.
Precision and Performance
Trunnion ball valves are designed to handle higher pressure and larger pipe sizes, making them ideal for industrial applications. They also have lower torque requirements, providing more precise control of flow.
However, their complex design can make them more expensive and difficult to maintain. On the other hand, floating ball valves are more cost-effective and easier to repair, but they may not be suitable for high-pressure environments.
Ultimately, the choice between these two types of valves will depend on the specific needs and requirements of the system, and striking a balance between precision and performance.
Real-World Applications
Trunnion and floating ball valves are two common types of valves used in various real-world applications, such as oil and gas, chemical, and water industries.
Each type has its own set of pros and cons, making it important to carefully consider the specific requirements of a project before choosing between them.
Trunnion ball valves are known for their durability and ability to handle high pressure and flow rates, but they can be more expensive and have a higher torque requirement for operation.
On the other hand, floating ball valves are cost-effective and easy to operate, but they may not be suitable for high-pressure applications. Ultimately, the choice between trunnion and floating ball valves will depend on the specific needs and conditions of the application.
Longevity
When it comes to longevity, both types have their own advantages and disadvantages. Trunnion ball valves have a fixed axis or trunnion that supports the weight of the ball, making them ideal for high-pressure and high-temperature applications.
This design also reduces the wear and tear on the sealing components, increasing their longevity. On the other hand, floating ball valves have a simple design and are suitable for low pressure applications, but they may experience more wear and tear on the sealing components over time.
In terms of longevity, trunnion ball valves may have an edge, but proper maintenance and installation can ensure a longer lifespan for both types of valves.
Learn All About Trunnion vs Floating Ball Valves
In conclusion, both trunnion and floating ball valves have their own unique advantages and disadvantages. It is important to carefully consider the specific needs and requirements of a project when choosing between the two.
Remember to weigh the pros and cons carefully before making a decision. If you need further guidance or assistance, don’t hesitate to consult a valve expert. Make an informed decision and choose the valve that will best serve your needs and provide optimal functionality for your project.
