What is a Concentric Butterfly Valve?
A centric or concentric butterfly valve is the most common type of butterfly valve arrangement. The basic components of a concentric butterfly valve are the body, seal, disc, and stem.
The flow medium in the system is controlled by a rotary disc in the concentric butterfly valve. The stem is in the center of the disc, and the disc is in the center of the valve body. The disc stays in the passage, but it provides very little resistance to the flow due to its thinness. When the seat opens or shuts, some portions of the disc are always in touch with or scraping the seat. The seat is subjected to friction every time the valve is utilized as a result of this arrangement.
Concentric butterfly valves are also known as ‘resilient seated’ butterfly valve as it depends on the flexibility of the seat rubber when the flow is closed, for the reliability of the seal.

What is a Butterfly Valve?
A butterfly valve is a part of the quarter-turn valve family (bi-directional) that is used to prevent, control, or start flow. Quarter valves include the type of valves in which the disc rotates 90 degrees between the fully open and fully closed positions.
The “butterfly” is a metal disc attached to a rod. When the rod is turned, it rotates the disc by a quarter such that the disc falls perpendicular to the flow and stops it. And to restore the flow, the rod rotates the disc back to the original position, i.e. away from the flow. The valve can also be opened in stages to control the flow.
