Valves are a component in a piping system that is used to control the flow of the media through the system which can be achieved by the manipulation of a few types of obstructors within the valve.

The flow of a product via a pipeline is managed by a particular style of “quarter-turn” valve called a butterfly valve. This valve has been in use for a while; it can be used to restrict the flow of solid, liquid, or gas materials and has a wide range of uses.

Since their initial debut in the 1930s, they have been used by numerous industries. As the name implies this type of valve, is frequently composed of cast iron, which comes from how well its disc works. The valve opens or closes when the metal disc that is a component of its construction takes a quarter turn.

A rod is connected to the disc, sometimes known as the “butterfly.” The disc spins (a quarter turn) when the butterfly valve is fully opened, permitting almost unhindered fluid flow. To decrease flow, you can also open the valve gradually.

The valve can be closed by turning the butterfly (disc), which stops the flow of fluid. Regardless of the disc’s position, it is always perpendicular to or parallels the flow, causing the pressure to diminish.

To regulate the flow and pressure, there are electric actuated butterfly valves that control the flow of material through a circular pipe or tube. They are for use in controlling the flow of compressed air and other gas, or for vacuum service.

Advantages Of Lugged butterfly valves

Lugged butterfly valves are one of the most versatile types of valves on the market. They can be used in various applications and offer many advantages over other valves. Here are five of the main benefits of lugged butterfly valves:

Lugged Butterfly Valve

They are highly durable and can withstand high pressure and temperature.

They offer a tight seal and are less likely to leak than other types of valves.

They have a wide range of options for customization.

They have a very compact design, which makes them ideal for use in tight spaces.

Disadvantages Of Lugged Butterfly Valve Lugged butterfly valves are one of the most popular types of butterfly valves on the market. But you should be aware of some disadvantages to using this type of valve before making a purchase.

They are more expensive than other types of butterfly valves

They are not as easy to install because of the larger size.

They are not as easy to maintain as different types of butterfly valves.

They are not as versatile as other types of butterfly valves.

Wafer Butterfly Valve

Application Comparison

Coming to the topic of butterfly valves lug type vs wafer type, while wafer-style butterfly valves cannot be utilized for end-of-line services, lug-style butterfly valves can. The entire line must be shut down if there is a need for maintenance on a line with a water-style butterfly valve.

Ball valves have mostly been superseded with butterfly valves in many sectors. This is particularly true for businesses that deal with petroleum because these products are less expensive and simpler to install.

Many different industries employ butterfly valves, including:

Oil and gas

Chemical processing

Water and wastewater processing and transportation

Food processing



Shipbuilding and shipyards


The butterfly valves have a variety of uses, furthermore, they can also be divided into many kinds. However, the most prominent discussion remains on the lug type vs wafer butterfly valve usage.
