What Do Butterfly Valves Do, And Where Do You Use Them?

Knowing the Parts and Functions of a Butterfly Valve 

In our water system, we have different parts and components. Each component has their own function or purpose, and all together, these components make the whole system work. One component is the valve. As we all know, we have different types of valves and one of them is called the butterfly valve. So, what is a butterfly valve and what is the function of this kind of valve?

A butterfly valve is designed with a quarter turn, and it is used to stop, control and start the flow. We have the different parts of a butterfly valve, first is the disc. This disc is mounted on a rotating shaft. When you close your butterfly valve, this disc will fully block the line and when you open your butterfly valve, the disc is at a right angle to the flow of gas or liquid in the system. This disc is like a plug in a plug valve, a gate in a gate valve, or a ball in a ball valve, and it is mainly used to stop the flow. Another part of a butterfly valve is the valve stem. This valve stem can be a one piece shaft or two piece shaft. A valve seat on the other hand utilises the interference fit between the disc edge and the seat to provide a shutoff. All of these parts of a butterfly valve work together to exhibit the main function of the valve in the system. 

The use of a butterfly valve is noted for less space requirements because of its compact design. This is also inexpensive to build because of the simple design of the components that just function for a perfect fit in the system, and the most advantage of a butterfly valve compared to other types is that it is easy to use and fast to open. 

Knowing a part of your system can make you utilize and maximize the use of it. So, it is better to have a little background check on your valve.
