Product Description

The Double Eccentric Double Flange Butterfly Valve is one important kind of water works valves. The main function of butterfly valve is to control fluid flow rate in pipeline: turn gear box or Other actuator, the disc will rotate; lock the disc at the specified angle by locking device; the fluid flow rate depends on the disc angle; when the disc is turned 90℃ to the valve bore center line, the pipeline is cut off. The ductile iron body butterfly valves are widely used in industry of potable water, sewage, and sea water. Considering different connecting ends, the water work butterfly valve is classified in wafer type butterfly valve, lug butterfly valve, and flange butterfly valve, etc. According different material, it’s classified in ductile iron GGG50 GGG40 butterfly valve and stainless steel butterfly valve. As well as manual butterfly valves, we can also provide pneumatic butterfly valve and motorized butterfly valve.
