Wafer type butterfly valves and lug type butterfly valves are two common types of valves used in various industrial applications. While both types serve the same purpose of controlling the flow of fluid in a pipeline, there are some key differences between them that make each type better suited for certain situations.
One of the main differences between wafer type butterfly valves and lug type butterfly valves is the way they are installed. Wafer type butterfly valves are installed between two flanges using bolts and nuts, making them easy to install and remove. On the other hand, lug type butterfly valves have lugs on the valve body that allow them to be bolted directly to a pipeline without the need for additional flanges. This makes lug type valves more secure and stable, especially in high-pressure applications.
Another difference between the two types of valves is their ease of maintenance. Wafer type butterfly valves are easier to maintain and service due to their simple design and installation. They can be easily removed from the pipeline for cleaning or repairs. Lug type butterfly valves, on the other hand, are more difficult to maintain as they are bolted directly to the pipeline.
This makes it harder to remove them for maintenance, especially if they are installed in a tight space

In terms of cost, wafer type butterfly valves are usually more cost-effective than lug type butterfly valves. This is because wafer type valves are simpler in design and easier to manufacture, making them more affordable for industrial applications. Lug type butterfly valves, on the other hand, are more complex in design and require additional materials for installation, making them more expensive.
When it comes to performance, both wafer type and lug type butterfly valves have their advantages. Wafer type valves are lightweight and have a lower pressure drop, making them ideal for low-pressure applications. Lug type valves, on the other hand, are more robust and can handle higher pressures and temperatures, making them ideal for high-pressure applications.
In conclusion, both wafer type butterfly valves and lug type butterfly valves have their own unique advantages and disadvantages. The choice between the two types ultimately depends on the specific requirements of the industrial application. Wafer type valves are more cost-effective and easier to maintain, while lug type valves are more secure and stable in high-pressure applications. Ultimately, it is important to consider the specific needs of the application when selecting the type of butterfly valve to use.
