    Top 10 Butterfly Valve Manufactures Worldwide

    Butterfly valve is a type of quarter-turn valve to regulate the flow. It operates by rotating a disc that mounted on a rod. The disc blocks the flow while the valve is fully closed.  When it is fully opened, the disc rotates a quarter turn so that the fluid can pass through.
