We are a leading manufacturer of water works valves, we have more than 15years experience in producing Concentric Fully Lug Type Butterfly Valve.
The fully lug type Butterfly Valve is one kind of important water works valves like gate valve and Check Valve, which is widely used in water transmission system. The main function of Concentric lug Type Butterfly Valve and Wafer Type Butterfly Valve is to control fluid flow rate in pipeline: turn handle 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. Considering different connecting ends, the Water Work Butterfly Valve is classified in wafer type butterfly valve, Lug Butterfly Valve, and Flange butterfly valve, etc. The ductile iron butterfly valves are widely used in industry of potable water, sewage, and sea water.
