The butterfly valve, also called the flap valve, is a valve with a simple structure. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, simple and fast in operation, but also has good flow regulation and closing and sealing characteristics at the same time. It has been developed in the past ten years. One of the fastest valve varieties.
Butterfly valves are widely used. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, and liquid metal. It mainly plays the role of cutting off and throttling on the pipeline.
The variety and quantity of butterfly valves continue to expand, and are developing towards high temperature, high pressure, large diameter, and high sealing. Now butterfly valves have long service life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level.
Pneumatic flange soft seal butterfly valve has compact structure, easy 90 ° rotary switch, reliable sealing and long service life. It is widely used for water supply and drainage in waterworks, power plants, steel mills, papermaking, chemical industry, catering and other systems as regulating and cut-off valves.
