Butterfly Valves :

A Butterfly Valves is from a family of valves called quarter-turn valves. In operation, the Valve is fully open or closed when the disc is rotated a quarter turn. The “butterfly” is a metal disc mounted on a rod.

When the Butterfly valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow .

Butterfly valves are commonly employed in various industrial applications. They are operated by a rotating disc, which is positioned perpendicular to the flow. When the valve is opened, fluid flows smoothly through the passageway. This design allows for precise control and efficient regulation of fluid flow, making them widely used in numerous industries, such as oil and gas, water treatment, and chemical processing.  Butterfly valves control fluid flow using rotating discs, unlike ball valves. 

Butterfly Valves Ideal for precision throttling and on-off applications, especially in lighter-weight piping systems, the Flowserve family of butterfly valves is often specified for its versatility. Outstanding throttling accuracy for process control is achieved through low-friction, erosion-resistant sealing surfaces with very low operating torques. A broad range of applications can be met via metal- and soft-seated designs as well as lined versions for corrosive and hygienic applications.
