What is a butterfly valve?

butterfly valve is a type of flow control device that uses a rotating disc to regulate the flow of a fluid. The disc is positioned in the center of the pipe and operates similarly to a butterfly's wings, hence the name.

How does a butterfly valve work?

When the valve is closed, the disc blocks the pipe completely. When the valve is fully open, the disc is rotated a quarter turn to allow an almost unrestricted flow. Partially opening the valve allows for throttling the flow.

What materials are used to make butterfly valves?

Butterfly valves can be made from a variety of materials, including cast iron, stainless steel, plastic, and other materials depending on the application and the fluids being handled.
