Plumbing valves come in many different types with a variety of applications. Today we will compare two of the most commonly used valves, globe valves, and ball valves. These differences in structure and application will be discussed in this comparison. For those who are trying to decide between these two types of valves and don’t know which is better for their needs, Cair Euromatic Automation has gathered the most valid and reliable information for you. Find out what the main differences are by reading on.
How Does a Ball Valve Work?
In two of our articles, we discuss the types of ball valves and the parts of ball valves, but we do not cover plumbing valves at all in those articles. To illustrate the differences between ball valves, we are going to give you a brief overview of how they work. Let’s take a closer look at how ball valves work.
The shape of a ball valve is similar to that of a bead. The center hole is the same size as the pipe, but there is one difference. To control the flow, it has a perforating and pivotal ball inside its structure. The valve is open when the hole inside the ball aligns with the flow, and the handle is flat and aligned with that flow. The valve closes when the ball is turned 90 degrees. When the valve is closed, the handle is perpendicular to the pipe and the flow.
How Does a Globe Valve Work?
A separate article on globe valve parts and a separate article on globe valve types have already been published. A brief explanation of how a globe valve works will help you understand the differences between globe valves and ball valves. Control valves are also known as globe valves in plumbing. They are named after their spherical bodies. Globe valves have an opening and a seat into which a movable disk can be screwed to open or close them.
What are the main differences?
In our previous discussion, we discussed the functions of globe valves and ball valves, as well as their structures and components. Previously, we discussed how globe valves and ball valves open and close the flow. Globe valves are used to control and throttle the flow, whereas ball valves cannot control the flow and can only be used to close it. Ball valves are well-suited for closing the flow without pressure drops, whereas globe valves regulate the flow.
Globe valves, on the other hand, have a stem and a plug which move vertically, while ball valves have a stem and a ball that rotate horizontally.
When you need to keep the flow closed for an extended period, use a ball valve. When a high-pressure system, such as fire hoses, is involved, a ball valve is more efficient.
If flow regulation is the issue, a globe valve is the best choice. Some applications of globe valves require tight control of flow, such as cooling systems, fuel systems, and steam systems. For ball valves, there are no restrictions on installation, as there are for globe valves. Furthermore, ball valves are lighter than globe valves. A ball valve is also more durable, works well after so many cycles, and is more reliable even after a very long period of mistreatment.
Cair Euromatic Automation is the leading ball valve supplier in India. We offer various types of industrial valves, like ball valves, control valves, butterfly valves, and many more.
