Stainless Steel Metal Butterfly Valve
The structural length and overall height of the butterfly valve are short. The opening and closing a quick. And it has good fluid control characteristics. The structural mechanism of the sanitary butterfly valve makes it most suitable for the production of large diameter valves. When the butterfly valve is required to control the amount of flow, it’s most important to properly select the size and type of butterfly valve so that it can work properly and effectively.
Usually, in throttling, regulation control, and mud medium, it is required that the structural length be short and the opening and closing speed be quick. For low-pressure shut-off, it is recommended to use a butterfly valve.
In two-position adjustment, necking channel, low noise, cavitation and gasification phenomenon, a small amount of leakage to the atmosphere and abrasive media, butterfly valve can be used. Throttling adjustment under special working conditions, or using a butterfly valve under working conditions where the wear is serious and the temperature is low, we need to use three eccentric or double eccentric dedicated butterfly valve that is specially designed with a metal sealing and a regulating device.
The centerline butterfly valve is suitable for freshwater, sewage, seawater, brine, steam, natural gas, food, medicine, oil, and other pipelines that are required to be completely sealed, and where the gas test leakage is zero, the life expectancy is high and the working temperature is between-10 degrees Celsius and 150 degrees Celsius.
The soft sealing eccentric butterfly valve is suitable for the two-way opening and closing and regulation of ventilation and dust pipelines and is widely used in the gas pipelines and waterways in metallurgy, light industry, electricity, and petrochemical systems. The metal-to-metal linear sealing double eccentric butterfly valve is suitable for urban heating, gas supply, water supply, and other gas, oil, acid, and other pipelines, as the regulating and throttling device.
Metal-to-metal area sealing three-eccentric butterfly valve can be widely used in petroleum, petrochemical, chemical, metallurgy, power, and other fields in addition to being used as a large pressure swing adsorption (PSA) gas separation device control valve. It is a good replacement product for the gate valve and shut-off valves.
