An automatic butterfly valve is a type of butterfly valve that is operated by an actuator—electric, pneumatic, or hydraulic—allowing remote or automated control of fluid flow. Unlike manual valves, automatic butterfly valves can be integrated into control systems for precise, real-time flow regulation without human intervention. They are ideal for applications that require frequent or rapid operation, or where manual access is limited. Automatic butterfly valves are commonly used in water treatment, HVAC, chemical processing, and industrial automation due to their efficiency, reliability, and compatibility with modern control systems.
