A butterfly valve considered as a regulating device which is used to shut off the flow of a fluid. It is also known as quarter turn valves because it provides 90-degree rotary motion for the stoppage. They often came in large sizes but short in length and are of the very lightweight. They possess very low torque requirements. It is used with globe and ball valves in some applications.
Advantages
Butterfly valves are the best choice for all kinds of butterfly valve requirements. These are very cost effective and the performance of the product is also very high. These valves are similar to ball valves but have a little more advantages. The dist in the butterfly valve is lighter than a ball and it requires less structural support than a ball valve. Butterfly valve does not require high maintenance and hence widely used in industrial applications. They also require a little space and it is very easy to open them.
Components
There are four main components of a butterfly valve: body, disk, stem, and seat.
1. Butterfly valve body
The body of the butterfly valve fits between two pipe flanges. It is one of the main components of the butterfly valve. Lug and wafer body design are most common among them.
2. Butterfly valve disk
The disk is used to stop the flow of the liquid. The disk of the butterfly valve has a number of variations in its design and orientation to improve the flow, sealing or torque.
3. Butterfly valve stem
It is available in two design one- piece shaft or two-piece design. For the proficient selection of the material with respect to its cost as well as mechanical properties, it is confined from the media.
4. Butterfly valve seat
It provides the shutoff between the disk edge and the seat. Elastomers and polymers are used to make the seat of the butterfly valve. It may be bonded with the body or may be locked in.
Applications
Some of the common applications of the butterfly valve are:
On/ off isolation, Dead- end service, heating, ventilation, and air conditioning system, Industrial process piping, Municipal raw water intake, Municipal chlorinated water systems (2000 ppm), Municipal feed water and reservoir, throttling and process control, full vacuum, blower installations.
