What is the function of butterfly valve
1. When the butterfly valve is used for throttling adjustment under special working conditions, or requires strict sealing, or severe wear, low temperature (cryogenic) and other working conditions, it is necessary to use a specially designed metal seal with a triple eccentric or double eccentric adjustment device ground special butterfly valve.
2. Metal-to-metal wire-sealed double eccentric butterfly valve is suitable for gas, oil, acid and alkali pipelines such as urban heat supply, gas supply, water supply, etc., as a regulating and throttling device.
3. Butterfly valves are suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil products and Various acid-base and other pipelines.
4. The soft-sealing eccentric butterfly valve is suitable for two-way opening and closing and adjustment of ventilation and dust removal pipelines, and is widely used in gas pipelines and waterways in metallurgy, light industry, electric power, and petrochemical systems. The metal-to-metal surface-sealed triple-eccentric butterfly valve is not only used as a program control valve for a large-scale PSA gas separation device, but also can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields.
