There are many types of butterfly valves, which can be divided into flange type, wafer type, butt welding type and lug type according to different connection methods. Among them, the lug butterfly valve is a special clip-on butterfly valve. There are protruding ears at both ends of the valve body. The valve can be installed on the pipe end or sandwiched between two pipe flanges through bolts. It has the advantages of flexible installation, space saving and convenient maintenance.
