The Selection of the Size and Type of Butterfly Valve
The butterfly valve has a short structural length and overall height. Its speed of opening and closing is quick. It has good fluid control characteristics. Structurally, the butterfly valve is most suitable for the production of a large diameter valve. When the butterfly valve is used to regulate the flow, the most important thing is to properly select the size and type of butterfly valve to make it work properly and effectively.
Usually, in throttling, regulation control, and mud medium, it’s required that the structural length is short, opening and closing speed is quick. It’s recommended to use a sanitary butterfly valve under low-pressure shut-off occasions.
In situations such as two-position regulation, necking channel, low noise, cavitation and gasification, a small amount of leakage to the atmosphere, abrasive media, butterfly valve can be used. Throttling under special working conditions, or strict requirement for sealing, or using butterfly valves under severely abrasive and low-temperature working conditions, three eccentric or double eccentric special butterfly valve that has special-designed metal sealing with regulating device needs to be used.
The centerline butterfly valve is suitable for fresh water, sewage, seawater, brine, steam, natural gas, food, medicine, oil, and other pipelines that require complete sealing, zero leakage from the gas test, higher life expectancy, and a working temperature between -10~150°C.
The soft sealing eccentric butterfly valve is suitable for two-way opening and closing and regulation of ventilation and dust-removal pipelines and is widely used in gas pipelines and waterways of metallurgy, light industry, electricity, petrochemical system.
The metal-to-metal linear sealing double eccentric butterfly valve is suitable for pipelines of urban heating, gas supply, water supply, gas, oil as regulating, and throttling devices. In addition to being used as the control valve of large pressure swing adsorption (PSA) gas separation device, metal-to-metal surface sealing three eccentric butterfly valves can also be widely used in petroleum, petrochemical, chemical, metallurgy, electric power, and other fields. It is a good replacement for the gate valve and shut-off valve.
