The Floating ball valve and the trunnion ball valve are the unique ball valves that work in several manufacturing processes.

In the article, we will outline several features and discuss extensively on how these features help make these types of valve better and unique.

Let’s dive in.

· The Application in the Industry.

The good thing about the floating ball valve is that it is very ideal when dealing with low and medium pressure points. This is one of the reasons it is highly regarded in any industry.

With the trunnion valve, it can only be used in situations where high pressure is required. It can also be used in situations where the size is 60 inches at most.

This ball valve is referred to as a DBB valve where DBB stands for the Double-block-and-bleed. The good thing about this valve is that it can be able to block downstream and upstream media.

· The appearance of the valve body.

The good thing about these valves is that it has the best appearance that you would love. However, a unique appearance feature comes up on the trunnion ball valve that has a round bottom.

· The sealing ability at the surface.

The principle of sealing in both valves are different. In both the floating ball valve and the trunnion ball valve, the material used for the sealing is entirely different. The sealing surface of the floating ball valve is unique because it can withstand the pressures of the floating ball.

· The operation.
When trying to compare the floating ball valve and the trunnion valve, the floating ball valve is seen to have an upper stem. The presence of this upper stem leads to the ball having a little form of displacement.

The pressure of the inner medium is what aids in the sealing of the floating ball valve, especially when the floating ball valve is not open.

When the trunnion ball valve is not open, the ball does not produce any displacement.

· Working characteristics.

When discussing ball valves, it is important to note that the trunnion ball valves are longer than the floating ball valve. They are also the smallest.

The trunnion ball valve is easier to operate than the floating ball valve. However, the floating ball valve is relatively safer to use and they give you the best results and value for your money.

There are various other features of the trunnion ball valve and the floating ball valve.

These features include the ability to release and increase pressure automatically. These valves are designed to give you the best results when it comes to production.

CONCLUSION.

The best thing we have done for you in this article is to give you the right details about the floating ball valve and the trunnion ball valve. They are both very relevant in process control and manufacturing industries.

The main problem that people face is finding the right ball valve that will suit your needs but cannot find the right tool for your manufacturing process. There is a right place for you. Shanghai Datun Valve Pipe Engineering gives you the best solutions.
