The use of the pneumatic valve flange butterfly

in general, the throttling and adjusting control and mud medium, demand structure length is short, the opening and closing speed. Low voltage cutoff, it is recommended to use pneumatic valve flange butterfly.
, in two position adjustment, reducing channel, low noise, have spirit of hole and gasification phenomenon, a small amount of leakage into the atmosphere, the corrosive medium, can choose pneumatic valve flange butterfly.
, throttling at the special condition or request strictly, or severe wear and tear, low temperature of operating mode under the condition of using pneumatic valve adjustment, need to use special design of triple eccentric metal sealing with conditioning or special flange of double eccentric butterfly pneumatic valve.
triple eccentric butterfly, metal to metal surface seal pneumatic valve in addition to the large variable pressure adsorption gas separation devices as program control pneumatic valve use, also can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields, is the brake of the pneumatic valve, pneumatic valve up to now, good alternatives.
pneumatic valve, flange center line butterfly is suitable for the requirements to completely sealed, gas leak to the other, the demand is higher, the working temperature in - service life - Degree of fresh water, sewage, sea water, salt water, steam, gas, food, pharmaceutical, oil and all kinds of acid and alkali, and other lines.
line, metal to metal seal eccentric double flanged butterfly pneumatic valve is suitable for the city heat supply, gas supply, water supply and gas, oil, acid and alkali, such as line, as regulation and river closure device.
, flange soft eccentric butterfly pneumatic valves open and close and is suitable for ventilation and dust removal pipe two-way adjustment, widely used in metallurgy, light industry, electric power, petroleum chemical industry system of gas pipeline and channel, etc.
