Bidirectional seal butterfly valve.Fire safe butterfly valve,Triple
eccentric butterfly valve,CLASS 600 butterfly valve
Coosai butterfly valve provide a variety of types to meet different
face to face dimension.Such as wafer type,Lug type,Falnge type.
ring joint type and Butt weld type.it is suitable for acid,alkali
and other corrosive medium with both high and low temperature due
to wide material selelction.Especiallu in large-diameter butterfly
valve ,It is continuously replacing the shut off valve such as gate
valve and ball valve with its's advanvantage of zero leakage,
Meanwhile it is also continuously replaceing the regulating
valves.Such as globe valve with it's excellent performance in
regulation and control.
