Butterfly pneumatic valve is suitable for flow control

flow control pneumatic valve adjustment. Because in the pipeline pressure loss is relatively large pneumatic butterfly valve, pneumatic valve, about three times the brake control pneumatic valve when the choice, should consider pipeline under fully considering the influence of the system pressure loss, should also consider closing line CD media robustness under pressure. In addition, flexible pneumatic seat materials at high temperature must be considered restricted by temperature. The length and the small pneumatic valve, quick opening and closing the overall height of the structure, and has good flow control characteristics, the principle of the butterfly, the most suitable for big pneumatic valve production suitable structure. When asked to use flow control, the most important right choosing pneumatic valve, pneumatic valve size and type of work so that it can correctly and effectively. Normally, throttling, adjusting control and mud, the need to structure length is short, opening and closing speed ( / circle) 。 Low cut off ( The pressure difference) , it is recommended to use the butterfly. In the adjustment of the double digits, reduced the channels, low noise, wind erosion and gasification, leak into the atmosphere of a small amount of grinding media, phenomenon, you can use a butterfly. The gas under special working conditions, or demanding seal or serious wear and tear, low temperature ( Low temperature) And other working conditions, the use of the pneumatic butterfly valve, use three or two eccentric eccentric butterfly pneumatic valve and special adjustment device specially designed metal seal. Butterfly application requirements is completely sealed pneumatic valve, gas leak detection is zero, the higher working temperature - life requirements ℃? Fresh water, sewage, water, salt water, steam, gas, food, medicine ℃, petroleum and chemical industry and so on all kinds of pipes. Soft seal, open and close the ventilation and dust removal pipe control way, widely used in metallurgy, light industry, electric power, petrochemical and natural gas pipeline system and other waterways with butterfly pneumatic valve. Metal to metal sealed double eccentric butterfly pneumatic valve for urban heating, gas, water and other gases, oil, acid, alkali line for adjusting and throttling device. Metal to metal seal, unless it is as large (pressure swing adsorption (psa) PSA） Gas separation device using process control pneumatic valve, pneumatic valve butterfly face, can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields, pneumatic valve, when the gate by the pneumatic valve is a good choice.
