FAQs
What is flange butterfly valve?
A flange butterfly valve functions as a flow control device which enables both precise shutoff and regulation of liquid and gas applications. The valve structure includes two cylindrical components which form the disc and stem parts. The disc contains a rod or stem which extends through the seating material to enable the device to open or close.
What are the applications of flange butterfly valves?
The flange butterfly valve serves as a standard component in water treatment systems and chemical processing facilities and petroleum refineries and natural gas pipelines and other industrial operations.
