Understanding Double Flanged Butterfly Valves:

A double flanged butterfly valve, a vital component in fluid control systems, is distinguished by its two flanged connection points. This design ensures easy installation and secure sealing within pipelines. The valve features a circular disc or "butterfly" that turns within the pipeline, effectively regulating the flow of fluids.

Operational Mechanism:

Similar to a standard butterfly valve, the double-flanged variant employs a rotating disc to control flow. When fully open, the disc aligns parallel to the flow direction, minimizing resistance for unrestricted passage. In the closed position, the disc turns perpendicular to the flow, effectively blocking it. The additional flanges enhance sealing capabilities and structural integrity, making it suitable for high-pressure applications.

Main Components:

1. Body: The outer casing housing internal components.
2. Disc: A circular or semi-circular plate that controls flow through rotation.
3. Stem: A rod connecting the actuator to the disc for opening or closing.
4. Actuator: The mechanism for operating the valve, available in manual, pneumatic, hydraulic, or electric options.
5. Seat: The surface against which the disc seals to control flow and prevent leakage when closed.
6. Flanges: Raised rims at both ends used for connecting the valve to pipelines or other equipment.
7. Bolts and Nuts: Fasteners securing the valve to pipelines or equipment.
