What is the difference between a lugged and double flanged butterfly valve?

Jan 15, 2024 | News

In this article, we will discuss the difference between a lugged and double flanged butterfly valve, and the benefits of using this butterfly valve. We will also provide examples and summarize the key points to help readers quickly understand the content.

A lugged butterfly valve and a double flanged butterfly valve are both valves used in various industries, but they have some key differences. A lugged butterfly valve has a lugged body and a disc that rotates around a central axis. The lugs are used to connect the valve to the pipeline, and the disc is used to control the flow of fluid.

A double flanged butterfly valve, on the other hand, has a double flanged body and a disc that rotates around a central axis. The double flanges are used to connect the valve to the pipeline, and the disc is used to control the flow of fluid.

The main difference between the two valves is the way they are connected to the pipeline. A lugged butterfly valve is connected to the pipeline using lugs, while a valve is connected using two flanges.

Benefits of Double Flanged Butterfly Valve

A valve has several benefits over a lugged butterfly valve.

Advantages

1. Easy Installation: A double flanged butterfly valve is easier to install than a lugged butterfly valve. The double flanges provide a larger surface area for connection, making it easier to connect the valve to the pipeline.

2. Improved Sealing: The double flanges on a valve provide a better seal than lugs, reducing the risk of leakage and improving the overall performance of the valve.

3. Increased Durability: The double flanges on this butterfly valve are more durable than lugs, reducing the risk of damage during installation and operation.

4. Better Flow Control: This butterfly valve provides better flow control than a lugged butterfly valve, as the disc can rotate 360 degrees, providing precise control over the flow of fluid.

Examples of Double Flanged Butterfly Valve

This butterfly valve is commonly used in various industries, including:

Chemical Industry

In the chemical industry, this butterfly valves are used to control the flow of corrosive fluids and gases. The valves are made of durable materials, such as stainless steel, to withstand the harsh conditions.

Water Treatment Industry

In the water treatment industry, these butterfly valves are used to control the flow of water and wastewater. The valves are designed to provide precise flow control, ensuring that the water is properly treated before being released into the environment.

Oil and Gas Industry

In the oil and gas industry, double flanged butterfly valves are used to control the flow of oil and gas. The valves are designed to handle high-pressure and high-temperature applications, ensuring that the flow of fluid is controlled accurately.

Conclusion

In conclusion, a double flanged butterfly valve is a better option than a lugged butterfly valve due to its easy installation, improved sealing, increased durability, and better flow control. The valve is widely used in various industries, including chemical, water treatment, and oil and gas. By understanding the benefits of this butterfly valve, industries can make informed decisions when selecting valves for their applications.
