Its core component is the rotatable butterfly plate, which can quickly open, close and adjust the fluid by rotating 90 degrees.
Performance: The butterfly valve has multiple advantages.
First, it has a compact structure, small size, light weight, easy installation and relatively low cost.
Second, the operating torque is small, the opening and closing are fast, and it is easy to realize automatic control.
Furthermore, the butterfly valve has good flow regulation characteristics, especially suitable for large-diameter pipelines.
Modern butterfly valves can achieve reliable two-way sealing through optimized design and the use of high-performance sealing materials (such as elastomers or metal hard seals) to meet the use requirements under different pressures and temperatures.
In addition, butterfly valves can be made of a variety of corrosion-resistant materials and can adapt to a variety of media such as water, air, steam, oil, mud and even corrosive chemicals.
Application scenarios: Butterfly valves are found in all walks of life.
In water treatment and water supply systems, butterfly valves are used for the on-off and flow control of pipeline networks.
The chemical industry uses its corrosion resistance and fast switching characteristics to control various fluids.
The HVAC system relies on butterfly valves to adjust the flow of hot and cold water to control the temperature.
The cooling water and circulating water systems of the power industry, as well as pipeline transportation and refining equipment in the oil and gas field, also use butterfly valves in large quantities.
In addition, butterfly valves are also indispensable control components in the food and medicine, metallurgy and mining, papermaking and other industries.
High-performance butterfly valves (such as three-eccentric butterfly valves) are more capable of handling harsh working conditions such as high temperature and high pressure, further broadening their application range.
