Butterfly valve is a common industrial valve, which is widely used in water treatment, petrochemical, paper making, food, shipbuilding and other fields. The main advantages of butterfly valves are simple structure, convenient operation, small flow resistance, good sealing performance and low maintenance cost. The main types of butterfly valves are semi-lug butterfly valves and full-lug butterfly valves. The difference between them lies in the structure and installation method of the valve body.

• The half-lug butterfly valve body has only half lugs at both ends, and the valve body can only be clamped between the two flanges with bolts. In this way, if the flange on one side is removed, the valve body will loosen or fall off. Half-lug butterfly valves are suitable for use in the middle of the pipeline and do not require replacement or repair.
• Fullly lugged butterfly valves have lugs at both ends of the body that allow the body to be bolted between two flanges. In this way, even if the flange on one side is removed, the valve body will not loosen or fall off. Full lug butterfly valves are suitable for use at the end of a pipeline or where replacement or repair is required.

The full lug butterfly valve has the following advantages over the half lug butterfly valve:

• Can withstand higher pressure and temperature, suitable for more working conditions.
• Can realize two-way sealing, effectively prevent fluid leakage and reverse flow.
• It can be disassembled or installed separately without affecting the normal operation of other parts.
• Can save space and material, reduce cost and weight.
