Usually, control and regulate the media in the throttle,mud, requiring a short length of the structure, opening and closing speed (1/4). Low cut-off (pressure difference), the recommended use butterfly.

The double adjustment, reduced in channel, low noise,there is the phenomenon of cavitation and gasification, a small amount of leakage to the atmosphere, with abrasive media, you can use butterfly. Special working conditions in the throttle, or require strict sealing, or badly worn,low-temperature (cryogenic) conditions using butterfly valve, seal with the adjustment three eccentric or specialdouble eccentric butterfly valve device use a specially designed metal.

The center line butterfly valve is completely sealed, the gas leakage test of zero, higher life expectancy, working temperature -10 degrees to 150 degrees of fresh water,sewage, sea water, salt water, steam, gas, food,pharmaceuticals, oil and various chemical and otherpipeline to the requirements.

Bidirectional opening and closing and regulating soft seal butterfly valve for dust removal by ventilation pipe, widely used in metallurgy, light industry, electric power,petrochemical and gas pipeline systems and other waterways.

Metal double eccentric butterfly valve suitable for city gas supply, heating, water supply, gas, oil, acid and alkaliline seal on the metal line, as the adjusting and throttling device.

Metal to metal seal three eccentric butterfly valve except as a large-scale pressure swing adsorption (PSA) gas separation plant process control valves, also can be widely used in petroleum, petrochemical, chemical,metallurgy, electric power and other fields, is a goodsubstitute of gate valve, globe valve.
