A flanged butterfly valve is a quarter-turn rotary motion valve designed to regulate or isolate fluid flow in pipelines. Its key component is a circular disc (the "butterfly") mounted on a rotating shaft. When the valve is open, the disc aligns with the flow direction, creating minimal pressure drop; rotating the shaft 90° positions the disc perpendicular to the flow, effectively blocking it. The flanged ends conform to standardized dimensions (e.g., EN 1092, ASME B16.5), enabling bolt-on connection to pipelines without welding.
Key features include:
Compact & Lightweight: Requires less space compared to gate or globe valves.
Rapid Operation: 90° rotation allows quick open/close (manual, electric, or pneumatic actuation).
Low Maintenance: Simple structure with fewer moving parts.
Versatility: Suitable for water, air, gases, and mild chemicals (depending on material).
Common applications: Water supply, HVAC, fire protection, food processing, and low-pressure steam systems.
