1. Generally, in throttling, regulating control and mud medium, the structure is required to be short in length and fast in opening and closing speed (1/4 revolution). Low pressure cut-off (small pressure difference), butterfly valve is recommended.
2. The butterfly valve can be used when two-position adjustment, narrow passage, low noise, cavitation and vaporization, a small amount of leakage into the atmosphere, and abrasive media.
3. When the butterfly valve is used under special conditions such as throttling adjustment, strict sealing, or severe wear, low temperature (cryogenic), etc., it is necessary to use a specially designed metal seal with a three-eccentric or double-eccentric adjusting device Dedicated butterfly valve for ground.
4. The centerline butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, and oil that require complete sealing, zero gas test leakage, high life requirements, and working temperature of -10℃~150℃. And various acid and alkali and other pipelines.
5. The soft-sealed eccentric butterfly valve is suitable for two-way opening and closing and adjustment of ventilation and dust removal pipelines. It is widely used in gas pipelines and waterways in metallurgy, light industry, electric power, and petrochemical systems.
6. The metal-to-metal wire sealing double eccentric butterfly valve is suitable for urban heating, gas, water supply and other gas, oil, acid and alkali pipelines, as a regulating and throttling device.
7. In addition to being used as a large-scale pressure swing adsorption (PSA) gas separation device program control valve, the metal-to-metal seal triple eccentric butterfly valve can also be widely used in petroleum, petrochemical, chemical, metallurgical, electric power and other fields. It is a gate valve and a stop valve. A good alternative product.
