When we purchase pneumatic ball valves for use, it will involve the upgrading of these products over a long period of time. When we update these products, the most important thing is to know what we need to do before replacing them. Only when we do a good job in these tasks can we ensure the smooth progress of product upgrading. So, what exactly do we need to do before upgrading?

The midline butterfly valve is applicable to fresh water, sewage, sea water, brine, steam, natural gas, food, medicine, oil products, various acid-base and other pipelines that are required to be completely sealed, have zero leakage in gas test, have high service life requirements, and have operating temperatures of - 10 ℃~150 ℃. The soft sealing eccentric butterfly valve is applicable to the two-way opening and closing and adjustment of the ventilation and dust removal pipeline, and is widely used in the gas pipeline and water channel of metallurgy, light industry, electric power, petrochemical system, etc. The metal to metal wire sealed double eccentric butterfly valve is suitable for urban heating, gas supply, water supply and other gas, oil, acid and alkali pipelines as a regulating and throttling device. In addition to being used as the program control valve of large pressure swing adsorption (PSA) gas separation device, the metal to metal sealing three eccentric butterfly valve can also be widely used in petroleum, petrochemical, chemical, metallurgical, electric power and other fields as a good substitute for gate valves and stop valves.
