Automatic control butterfly valves are industrial devices regulating fluid flow via 0-90° rotation of a disc. Key components include:

Actuators : Pneumatic/electric drives for rapid shutdown (<1s);
Body design : Double/triple eccentric structures enabling bidirectional sealing with low resistance;
Sealing materials : Metal (high-temp/high-pressure) or elastomeric (corrosive media).
Features : Compact size for large-diameter pipelines, emergency shutoff with accumulators (например., gas pipelines), and applications in water treatment, HVAC systems, и так далее.
