An automated butterfly valve is a type of valve that uses a disc or vane to control the flow of liquids or gases. It is a quarter-turn valve, meaning that it only requires a 90-degree turn to open or close the valve. The disc or vane is connected to a rod that is driven by an actuator, which can be either electric, pneumatic, or hydraulic. The actuator is controlled by a signal from a control system, allowing the valve to be opened or closed remotely. Automated butterfly valves are used in a variety of applications, including industrial processes, water treatment, and chemical processing. They are particularly useful in applications where a fast response time is required, as they can open and close quickly. They are also relatively inexpensive and easy to maintain, making them a popular choice for many industries.
