A butterfly valve is a type of flow control device that regulates the flow of fluid through a pipe. It consists of a circular disk that rotates within a valve body. The disk has a hole in the center, and as the disk is rotated, the hole aligns or misaligns with the pipe, allowing or blocking the flow of fluid. When the disk is rotated so that the hole is in line with the pipe, fluid can flow freely through the valve. When the disk is rotated so that the hole is perpendicular to the pipe, the flow of fluid is blocked. The valve is operated by a handle or lever that rotates the disk, or by an electric or pneumatic actuator.
what is a butterfly valve
A butterfly valve is a type of flow control device that regulates the flow of a fluid (such as water, air, or steam) through a pipe or duct. It consists of a circular disc (the “butterfly”) that rotates within a cylindrical body to open or close the flow. Butterfly valves are often used in industrial and commercial applications because they are relatively inexpensive, easy to install and maintain, and can handle high-pressure and high-temperature fluids. They are also commonly used in HVAC systems and plumbing applications.
