Butterfly Valve

It's a valve where opening and closing occur as a disc rotates around its central axis.
Its simple operation allows for quick action, making it widely used for not only low-pressure but also
high-pressure water, steam, air, and gas applications.
There are Lever, Gear, and Actuator Types depending on the operating method, and Wafer Type, Lug
Type, and Flange Type based on the installation method.
