Right now, there are over 3,000 facilities on the Outer Continental Shelf involved in the collection and treatment of oil and gas. These oils and gases are collected from wells -- a process that's performed using certain types of high pressure valves. Of course, different types of American ball valves offer different results and it's crucial that the right projects are executed with the right types of valves. Quite often, the types of valves being used are ball valves, sometimes referred to as pig ball valves or pig vales (as they are used in conjunction with pipeline pigging systems). Before sourcing and investing in valves, it is important to understand the degree to which these valves may differ from one another. Let's delve into some of the defining characteristics of ball valve types. Ball Valve Body Styles Before getting into the exact types of ball valves that are available at the moment, it's important to remember that there are actually four separate types of body styles. These include the single body, split body, top entry, and welded styles. The styles of ball valves available differ from the types of ball valves available. This means that there are number of potential variations that you can see in ball valves. The great thing about this variety is that it means that there is more potential applicability in ball valves than there would be otherwise. Full Port Ball Valves: Turning to the different body types of ball valves, we can first look at the full port ball valve. A full port ball valve is defined by the fact that it has an oversized ball. The oversized ball has a purpose -- it is the same size as the pipeline. This means that there will be less potential friction less than there would be if the ball wasn't the same size as the pipeline, and the flow involved is unrestricted. The valve is larger as well. Standard Port Valves: As their name suggests, standard port valve are quite usual. This means they're less expensive than some alternatives. This type of valve has a smaller ball, and therefore the valve itself is smaller as well. The flow going through the pipe will in turn be smaller and will typically be about one pipe size smaller than the valve's pipe size. This makes it more restricted. The V Port Ball Valve: The V port ball valve is named after its V-shaped seat. What this means is that the orifice through which the product flows can be more easily opened and closed to change its direction. While many like this idea, the construction of this type of valve means that it can't be used just anywhere. It typically needs to be utilized in a more secure site. When the valve is opened, it is usually opened at the "small end" first, which helps stabilize the flow control. Trunnion Ball Valve: Then there is the trunnion ball valve, which doesn't exactly give much away through its name. This type of valve will actually anchor the valve at the top and the bottom through a particular mechanism. This would be applied on larger and more high pressure valves. While this type of valve isn't going to fit everyone's needs, it can definitely be used for particularly high pressure projects. Manually Operated Valves: Finally, these types of valves can be closed more quickly than their counterparts. Though this is an advantage in some cases, it also means that there can be a risk of a water hammer. These can include an actuator, which can be pneumatically or motor operated, which will in turn be used for on/off flow control. The valve will also have a positioner, which transforms the control signal into an actuator position. The flexibility of this type of valve is certainly an advantage to most projects. Now that you're more familiar with the styles and types of ball valves, you'll be in a better position to make decisions that will support your needs. For more information, please contact us today.
Choosing a metal seated ball valve is essential for safe, efficient operations. Ball valves offer many benefits over other valves, including a more compact design, tight sealing, and easy operation. However, it&#;s important to know whether you will need a floating ball valve or a trunnion ball valve for your application. We&#;ll discuss the differences between the two and which types of applications you might choose one over the other for.
First, it&#;s important to understand the differences between floating and trunnion ball valves. Essentially, these are two different ways the valve supports the internal ball.
In a floating ball valve, the seats hold the ball in place and it floats around in the valve body. Upstream pressure from liquid or gas pushes the ball up against the downstream seat. This helps form a leak tight seal.

By contrast a trunnion metal seated ball valve uses shafts on the top and bottom of the ball to hold it in place. As such, the ball stays in place and does not move laterally inside the valve body. Instead, to provide a tight seal, floating seats surround the ball and are always in contact with it. With pressure, the seats press against the ball to form a seal.
Generally speaking, a floating ball valve will require more torque to operate than a trunnion ball valve. Also, floating ball valves are typically limited to smaller valves compared to trunnion options.
When considering which severe service ball valves to use for your operations, you&#;ll need to decide between floating and trunnion style ball valves. There are a few things to think about to help you choose the right option.
First, obviously cost will likely come to mind as you&#;re deciding on a valve. Typically, floating ball valves are less expensive than trunnion ball valves. This is because their design and manufacturing is less complex than trunnion ball valves. They don&#;t need spring-loaded seats or extra shafts to hold the ball in place, so there are fewer internal components.
However, you also need to consider your application. As we mentioned, floating ball valves tend to need more torque to operate. This is especially true as pressure and valve size increase. Therefore, in high pressure applications, many people choose trunnion style valves instead of floating ball valves. This is because they&#;re more versatile and can withstand higher pressures and they&#;re easier to operate in such conditions.
In addition, most of the time floating ball valves are much smaller. This is perfect if you&#;re working with smaller size pipelines. However, for larger pipelines, you may need a trunnion ball valve. These types of valves can often use much larger diameter balls than floating options.
