The Difference Between Ball Valve and Butterfly Valve

by Shalini Mathur HR Manager

If you're in the market for a new valve, you may be wondering what the difference is between a ball valve and a butterfly valve. Both types of valves have their advantages and disadvantages, which we'll explore in this blog post. So whether you're looking for a valve for a small application or a large one, read on to learn more about the difference between ball valves and butterfly valves.

Introduction

An industrial valve is a mechanical device that regulates, directs, or controls the flow of a fluid by opening, closing, or partially obstructing passageways in a pipe. Industrial valves are used in a wide variety of applications in many different industries.

There are two main types of industrial valves: ball valves and butterfly valves. Ball valves are used for on/off applications, while butterfly valves are used for throttling and regulating flow.

Ball valves have a round ball with a hole through the middle that is connected to a handle. The ball turns so that the hole is aligned with the flow of fluid. When the handle is turned to the closed position, the ball turns so that the hole is perpendicular to the flow of fluid, which blocks the flow of fluid through the valve. Butterfly valves have a disk-shaped element that is connected to a stem. The stem is connected to a handle. 

Both ball valves and butterfly valves can be used for either on/off or throttling applications. However, ball valves are typically used for on/off applications because they can be quickly opened and closed. Butterfly valves are typically used for throttling applications because they provide more precise control over flow rates.

What are Butterfly Valves?

Butterfly valves are one of the most widely used types of valves in industrial applications. They are simple in design and construction, and they can be operated with very low torque. Butterfly valves can be used for a wide variety of liquids and gases, and they are available in a variety of materials.

The Butterfly valve gets its name from the fact that the disk that controls the flow of fluid through the valve is shaped like a butterfly. The disk is attached to a shaft that goes through the center of the valve body. When the shaft is turned, the disk opens or closes, depending on which way it is turned.

Lug-type butterfly valves have bolts that attach the disk to the body of the valve, while wafer-type butterfly valves have a disk that is sandwiched between two halves of the body.

Butterfly valves are available in a wide variety of materials, including metals such as brass, stainless steel, and carbon steel, as well as plastics such as PVC and CPVC.

What is Ball Valves?

In a ball valve, the flow of fluid is controlled by a ball. The ball is usually located in the center of the valve and has a hole drilled through it. The ball rotates when the handle is turned to open or close the valve. A variety of materials are available for ball valves, including brass, bronze, stainless steel, and plastic. Ball valves are used in a variety of applications, including plumbing, automotive, and industrial applications.

The Difference Between Butterfly and Ball Valve

There are several key differences between butterfly and ball valves. Butterfly valves are typically used for larger-diameter piping, whereas ball valves are better suited for smaller-diameter piping. Butterfly valves also have a higher flow capacity than ball valves. Ball valves are less likely to leak than butterfly valves, and they can be used with a wider variety of fluids and gases.

Advantages and Disadvantages of Butterfly Valves

Compared to other valve types, butterfly valves offer several advantages. They are simple in design and construction and can be operated with very low torque. Butterfly valves are available in a wide variety of materials, and can be used for a wide variety of liquids and gases.

One of the main advantages of butterfly valves is their high flow capacity. Butterfly valves have a large diameter opening, which allows for a higher flow rate than other types of valves. Butterfly valves are also less likely to leak than other types of valves, such as ball valves.

Another advantage of butterfly valves is that they can be used with a wider variety of fluids and gases. Ball valves are typically only used with water or other low-viscosity fluids, but butterfly valves can be used with a variety of fluids, including oil and gas.

There are a few disadvantages to butterfly valves as well. One disadvantage is that they require more maintenance than other types of valves. Butterfly valves must be regularly lubricated and inspected to ensure that they are functioning properly. Another disadvantage of butterfly valves is that they are not as durable as other types of valves, such as ball valves.

Advantages and Disadvantages of Ball Valves

Ball valves offer several advantages over butterfly valves and other types of valves. This is because the ball is located in the center of the valve and has a hole drilled through it. When the handle is turned, the ball rotates to open or close the valve, creating a seal that is less likely to leak than other types of valves. This gives them the ability to withstand a wide range of temperatures and pressures. Ball valves are also relatively easy to install and maintain.

However, ball valves have a few disadvantages. One disadvantage is that they are not as durable as some other types of valves. They can also be more difficult to operate than other types of valves.
