Ductile Iron Butterfly Valve

Flanged type butterfly valves are used to connect and disconnect the fluid flow. These types of valves should never be used to control the fluid flow, so that when using these valves in lines, the disc must be completely open or fully closed and in all other cases there is a possibility of damage to the valves.
