What's ISO5211 butterfly valve ?

Double Flange Butterfly Valve, ISO5211 butterfly valve  is type of resilient seated butterfly valves,with integral flanges cast on both ends.

same as all the other butterfly valves,it's a quarter-turn valve that rotates 90 degrees to open or close the media flow.  

Butterfly valve is also used as flow regulalting valve,if the disc does not rotate to a full quarter-turn, it means the valve is partially open,we can regulate the flow of fluids by various openning angle.

(CV/KV chart of resilient seated butterfly valve is available on request)
