Lug Butterfly Valve – What it is and How it Works

May 20, 2023 | News

A butterfly valve is a type of quarter-turn valve used to regulate fluid flow. Its operation is simple, consisting of a disk-shaped valve element with a rotating shaft. When the shaft is turned, the valve opens or closes. One variation of the butterfly valve is the lug butterfly valve, which has some distinct advantages over the traditional butterfly valve.

What Is A Butterfly Valve?

As a leading lug butterfly valve factory, we will tell you more about lug butterfly valves. A lug butterfly valve is a type of butterfly valve that has threaded inserts, or “lugs,” around the perimeter of the valve body. These lugs allow the valve to be bolted into a pipeline. Then making it easier to install and remove without disrupting the entire piping system. The lugs also provide a more secure connection than standard butterfly valves, which can be prone to slipping or shifting under high pressure or vibration.

How Does A China Lug Butterfly Valve Work?

The operation of a lug butterfly valve is similar to that of a traditional butterfly valve. When the valve is in the open position, the disk-shaped valve element is rotated 90 degrees to allow fluid to pass through the valve body. When the valve is in the closed position, the valve element is rotated back to its original position, blocking the flow of fluid.

What Materials May Produce Lug Butterfly?

Lug butterfly valves are typically made from materials such as cast iron, ductile iron, or stainless steel. The valve body is designed with a circular opening and a disk-shaped valve element that rotates around a central axis. The disk is connected to a shaft that is turned by a manual handle, electric actuator, or pneumatic actuator.

Main 2 Advantages Of China Lug Butterfly Valve

Firstly, the lug butterfly valve is that it can be easily removed from the pipeline without disrupting the entire system. This is because the lugs allow the valve to be bolted onto the pipeline, rather than being welded directly to the pipe. The lugs from lug butterfly valve factory, also provide a more secure connection than standard butterfly valves. Then It makes them ideal for high-pressure or high-vibration applications.

Secondly, the lug butterfly valve is that it can be used in a wide range of applications. Meanwhile, it includes water treatment, chemical processing, and oil and gas production. They are also commonly used in HVAC systems, where they can be used to regulate the flow of air or water through the system.
