Pneumatic Electric butterfly valve

Butterfly valves are widely used in various industries. They have many remarkable advantages. Firstly, butterfly valves have a simple structure, small volume, and light weight. This makes them easy to install and maintain. Secondly, they have a low flow resistance, which can save energy and reduce operating costs. Thirdly, butterfly valves can be used in media with suspended solid particles, and can also be used in powder and granular media according to the strength of the sealing surface. They are widely used in gas pipelines and waterways of metallurgy, light industry, power and petrochemical systems. One of the user concerns about butterfly valves is their sealing performance. Although the sealing performance of butterfly valves is not as good as that of ball valves and stop valves, with the improvement of technology, the sealing performance of some high-quality butterfly valves has been greatly improved. Another concern is their application range. Due to the limitation of butterfly valve structure and sealing material, they are not suitable for high-temperature and high-pressure pipeline systems. The general working temperature is below 300 °C and PN 40. In conclusion, butterfly valves have their own unique advantages and application scenarios. When choosing butterfly valves, it is necessary to consider various factors such as working conditions and medium characteristics to ensure the normal operation of the pipeline system.
