Just what is the difference between a ball valve and globe valve anyhow? Both are types of valves used to control the flow of liquid or gas through a pipe, but they have different functions. Ball valves are mostly used to stop or start the flow of liquid or gas, while globe valves are often used to regulate the pressure and flow rate. Let’s take a closer look at these two types of valves and find out more about their individual benefits and drawbacks.
Ball Valves and its uses
A ball valve is a valve with a spherical disc that controls the flow of fluid through it. The sphere has a hole in it that allows fluid to pass through when it is aligned with the inlet and outlet ports, and blocks the flow when it is misaligned. Ball valves are durable and have a long lifespan, making them an ideal choice for many industrial and commercial applications.
Ball valves are available in a variety of sizes, materials, and configurations to suit a wide range of needs. The most common materials used for ball valves are brass, bronze, stainless steel, and plastic. Ball valves can be used for both high-pressure and low-pressure applications.
Globe Valves and its uses
A globe valve is a type of valve used to control flow in a pipeline. It consists of a spherical body with a hole through the center, and a disk-shaped valve seat with a hole in the center. The disk is attached to a stem that extends through the body. The stem is operated by a handle that allows the disk to be opened or closed.
Globe valves are used in a variety of applications, such as regulating the flow of water in a pipeline. They are also used in oil and gas pipelines, as well as in chemical plants. Globe valves are available in a variety of sizes and materials, depending on the application.
Ball Valve vs Globe Valve: some key Differences
There are several key differences between ball valves and globe valves that are worth considering when selecting the right type of valve for your needs. Perhaps the most obvious difference is in their shape – as their name suggests, ball valves have a spherical shape, while globe valves have a more cylindrical shape. This means that ball valves can be installed in tight spaces more easily than globe valves.
Ball valves are also less likely to become stuck in the open or closed position than globe valves, as the ball can rotate freely. Globe valves, on the other hand, have a stem that must be turned in order to open or close the valve, which means that they are more likely to become frozen in place. Ball valves are also typically less expensive than globe valves. You can purchase all types of valves from HONGDA at affordable prices.
Bottom Line
Ball valves are used in pipelines for on-off control of fluid flow. Globe valves are also used for on-off control, but they can be opened and closed to regulate the amount of fluid that flows through them by varying the degree to which they are opened.
