Tips: What is the double-flange butterfly valve?
The double flange butterfly valve is a type of flow control device used to regulate or isolate fluid in a pipeline. It is characterized by having two flanges on either side of the valve body, allowing it to be bolted directly between two sections of piping. This design ensures a secure and leak-proof connection, making it suitable for high-pressure and critical applications.
The valve consists of a circular disc or “butterfly” that is mounted on a rotating shaft. When the disc is turned perpendicular to the flow, it fully blocks the passage, and when it is aligned with the flow, it allows fluid to pass through. The double flange configuration provides extra strength and stability, making it ideal for larger diameter pipes and systems where the valve needs to withstand significant pressure or stress.
Double flange butterfly valves are commonly used in industries such as water treatment, chemical processing, and oil and gas. They offer advantages like easy installation, compact design, and efficient operation, but are typically more expensive and heavier than other butterfly valve types due to the additional flanges and robust construction.
