The Structure of Lug Type Butterfly Valves

Lug type butterfly valve uses stud bolts to connect the valve between two pipeline flanges. Its structure is simple, small in size, light in weight, and only consists of a few parts. And it only needs to rotate 90° to open and close quickly, the operation is simple, and the lug style butterfly valve has good fluid control characteristics. When the lug type butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, and it has better flow control characteristics.

The Application of Lug Type Butterfly Valves

Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, water treatment, etc., but also in cooling water systems of thermal power plants, gas pipelines in sulfuric acid industry, sulfur incineration, conversion and dry suction sections in sulfur acid system, which is the preferred brand of valves for sulfuric acid production plants. It is considered by the majority of users as a butterfly valve with good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, flexibility, and safe and reliable use. It has been widely popularized and used.

Lug type butterfly valves are also widely used as adjustment and shut-off devices in the pipelines of SO2, steam, air, gas, ammonia, CO2, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media in chemical, petrochemical, smelting, pharmaceutical, food and other industries.
