2 Piece Trunnion Mounted Ball Valve: A Versus Comparison

28 Jun.,2024

 

When it comes to choosing the right ball valve for your industrial application, there are a few factors that you need to consider. One of the most important decisions you'll have to make is between a 2 piece trunnion mounted ball valve and a regular ball valve. Both options have their own benefits and drawbacks, so it's essential to understand the differences between them before making a decision.

First and foremost, let's talk about what exactly a 2 piece trunnion mounted ball valve is. This type of valve consists of two main components - the body and the ball. The ball is attached to the stem, which is connected to the actuator. The trunnion mounted design provides additional support to the ball, ensuring that it stays in place and operates smoothly under high pressure and temperature conditions. This type of valve is commonly used in applications where high pressures are a concern, such as in the oil and gas industry.

On the other hand, a regular ball valve consists of a single piece body and ball. The ball is connected directly to the stem, which is controlled by the actuator. While regular ball valves are suitable for low to medium pressure applications, they may not be able to withstand the same high-pressure conditions as trunnion mounted ball valves.

One of the main advantages of a 2 piece trunnion mounted ball valve is its superior performance under high-pressure conditions. The trunnion mounted design provides additional support to the ball, allowing it to withstand pressures that would cause a regular ball valve to fail. This makes it an ideal choice for applications where high pressures are a concern, such as in the oil and gas industry.

Additionally, trunnion mounted ball valves are known for their excellent sealing performance. The trunnion design ensures that the ball is held securely in place, preventing any leakage or loss of pressure. This makes them a reliable choice for critical applications where leakage is not an option.

Another advantage of a 2 piece trunnion mounted ball valve is its durability. The additional support provided by the trunnion design helps to prevent wear and tear on the valve components, ensuring a longer lifespan and reducing the need for frequent maintenance and replacements.

On the other hand, regular ball valves are more cost-effective and easier to install. Their simpler design and construction make them a popular choice for applications where high pressures are not a major concern. However, they may not be suitable for applications where high pressures are a factor.

In conclusion, when it comes to choosing between a 2 piece trunnion mounted ball valve and a regular ball valve, it ultimately comes down to your specific application requirements. If you're working in an industry where high pressures are a concern and reliable sealing performance is essential, a trunnion mounted ball valve may be the best choice for you.

However, if you're looking for a cost-effective and easy-to-install option for low to medium pressure applications, a regular ball valve may be more suitable. Ultimately, both types of valves have their own benefits and drawbacks, so it's important to carefully consider your needs before making a decision.

In the end, the key is to choose a valve that meets your specific application requirements and provides reliable performance under the conditions you'll be working in. By weighing the advantages and disadvantages of each option, you can make an informed decision that will help you achieve optimal results in your industrial processes.
