The Importance of Choosing the Right Type of Butterfly Valve in 2024

Type of Butterfly Valves

The flow can be stopped, controlled, and started using a butterfly valve, which has a quarter-turn rotating motion. Quick-opening butterfly valves are one type. The valve can be fully closed or opened with a 90° handle revolution. They are typically employed in systems when a positive shut-off is not necessary. The following types of butterfly valve are covered in this article.

Understanding Butterfly Valves

Ball and plug valves are quarter-turn valves, as are butterfly valves. They are built with a pretty straightforward mechanism, are relatively small, and are made to suit two pipe flanges. They can be controlled manually or automatically using an integrated automatic actuation mechanism built into the pipeline’s process control system. They are perfect for on-and-off applications, but flow throttling is not one of their many uses.

Different types of butterfly valves

1. Wafer-style butterfly valves

Wafer butterfly valves are attached to two pipe flanges by long bolts that run across the valve body. Outside flange, holes may or may not be present in the valve body.

2. Lug-style butterfly valves

The bolts that go through the threaded inserts (or lugs) that protrude from the valve body secure lug butterfly valves between two pipe flanges. No nuts are used in either lug, and there are two different sets of bolts supporting the valve on either side.

3. Flanged butterfly valves

Double-flanged butterfly valves feature two flanges incorporated into the valve body on either side, which are the same size as the pipe flanges. To support the valve on either side, two sets of bolts and nuts are employed; this results in a sturdy attachment. 

4. High-performance butterfly valves

High-performance butterfly valves are designed by high-end butterfly valve manufacturer, to withstand the gases and liquids that general-purpose butterfly valves can’t process. They can process everything that general-purpose butterfly valves can process.

Importance of Choosing the Right Type of Butterfly Valve

The first and foremost crucial step to consider is the types of butterfly valves. The next step is to confirm whether a gas or a liquid will be circulating in the system. The media must meet specific hygienic requirements if it is corrosive, chemically inert, a food product, or a medical fluid. 

Knowing whether the valve is powered manually or automatically is crucial when it comes to the operation system. In the domestic and foreign markets, motorised butterfly valves are in high demand so these motorized butterfly manufacturer offers high-quality valves. The valve can be turned on or off remotely in one situation, such as from a control station, while the other requires someone to be present to operate it.

Factors to Consider When Choosing a Butterfly Valve

A. System requirements 

The sort of material that should be utilised for the valve will depend on the properties of the liquid or gas being regulated. Perfluoroalkoxy alkanes (PFA) and polytetrafluoroethylene (PTFE) are excellent options for monitoring corrosive or harsh compounds because they can tolerate these conditions. 

B. Material compatibility

On the other hand, we should consider the material adaptability of the butterfly valves. Not all valves will be placed indoors in a dry, ambient environment free of dust.  As a result, consider where you’ll install your valve and it differs to types of butterfly valve.

C. Flow rate and pressure 

Even though a butterfly valve is one of the most affordable options, it might not be able to handle certain process conditions, like a high-velocity line fluid. A globe valve might be a better choice in these circumstances. When considering the shut-off pressure of a valve, a butterfly valve frequently has a shut-off pressure of less than 10 bar.

D. Temperature range 

The key to choosing the best valve for your application is choosing the appropriate valve sizing. Problems with the operation of the valve or other parts of the system can result from an inadequately sized valve. Also, ascertain the temperature, pressure, and flow rate that your valve will be exposed to. Metal valves often have a higher temperature and pressure tolerance than plastic ones.

E. Operating conditions

The procedure for using the valve must also be taken into account. Determine if the valve will be manually operated or whether an actuator will be required to for it to automatically turn on and off.


Powerful tools to help, hinder, or restrain this flow include carefully positioned valves. One of the most popular industrial valves is the butterfly valve because of its adaptability. Additionally, they are available in different types of butterfly valve, so you can choose them wisely.
