A Glimpse into Butterfly Valves and Their Multiple Applications

Water supply systems have been a part of civilization for since the early ages where water was usually supplied to home via canals. Many others had wells that were constant sources of water which people had to physically draw. But, over time, the implementation of technology has made the process easier with the installation of modern plumbing solutions as well as pumps to supply water. Most of these pipes an intricate network in them and are fitted in a way that they do not burden the main source.

Defining Butterfly Valve and a Brief Overview

Butterfly valves are those equipments that help in controlling the internal flow of substances within pipes by rotating a disc into a quarter turn.  The valve is named due to the how its way of functioning which resembles that of a butterfly. The rod represents the body of the butterfly while the disk on top works like the wings by moving up and down in a right angled motion. Normally the disc is places either parallel or perpendicular to the flow of material. This valve is different compared to the others in terms of its ability to shift the pressure within. This object is primarily used in pumping stations and is also more compact with helps in making the installation process easier.

Due to its extensive use in large sectors, the butterfly valve is constantly in demand. According to the latest report published by Research Dive, the global butterfly valves market is expected to witness a significant rise in revenue from $9,028.1 million in 2020 to over $14,108.3 million by 2028 at a steady CAGR of 5.9% from 2021-2028.

The butterfly is segregated into four primary components known as the body, disk, stem, and seat. The body is where two pipes can be connected in a form known as lug or even wafer type which then leads to the valve disk. This portion is where the flow of material is restrained and this section is usually in need to constant updates so as to enhance the flow and operating torque of the valve. The next part is the stem which contains either one or two piece shaft design and the last section is the valve seat where the supply can be shut off. The disks edge and the sit interfere between the flow causing the material to stop in its tracks.

Variants of Butterfly Valves and Its Sources of Application

The plumbing and piping segment has a large variety of valves to make the supply of water and other substances easier. Butterfly valve being one of them is also divided into sub divisions that are made keeping in mind the various other elements that may require these valves. This valve is broadly categorized into three different types – plastic lines, rubber lines and metal.

• The metal ones are primarily used in situations that require the presence of high pressure or temperature.
• The rubber lines are a more economical option and don’t get tarnished easily. They mostly function well in lower temperatures.
• The plastic lines valves are extensively used for more sanitary purposes as well as to supply harsh chemicals due to its resistive power.

Various Utilizations of Butterfly Valves

The convenience factor as well as the ability to ensure control of low has led to application of the butterfly valves into different industries. Some of the prominent ones are as listed below:

1. Water Supply
2. Vacuum Service
3. Provision of Compresses Gas and Air
4. Lubrication System
5. Chemical and Oil Industries
6. Treatment of Wastewater
7. Power Generation
8. Food Processing

The use of butterfly valves has also led to renowned organization working on newer and more advanced variants to improve their functioning in the sectors mentioned above. For instance, in June 2021, Neles Corporation, a expert provider of flow control solutions, announced the launch of a new range of butterfly valves. These valves are highly advances and are also meant to function more efficiently without affecting the environment.
