Fluorine-butterfly explosion-proof FBQ641F46 - pneumatic ball valve 16 c images

Fluorine-butterfly explosion-proof FBQ641F46 - pneumatic ball valve 16 c is suitable for all kinds of corrosive medium and inflammable and explosive gas, liquid, dust and other dangerous environment of pneumatic valves, pneumatic actuator equipped with explosion-proof solenoid directional valves, explosion-proof letter opener, hand operation and attachments, and pneumatic ball valve lumen and sphere liner has corrosion resistance, ageing resistance of poly (fluorinated ethylene-propylene dilute, it has reliable corrosion resistance and impermeability, fundamentally from realized the real anti-corrosion explosion-proof requirements.






fluorine-butterfly explosion-proof pneumatic ball valve where have medium contact lined with fluoroplastic, so as to achieve superior corrosion resistance, and high chemical stability, can be applied to various concentration of alkali organic solvents and other corrosive gas and liquid medium in the pipeline, do switch cut off or adjust the use, widely used in petroleum, chemical industry, dye, pesticide, acid alkali production and other industries, is now the most ideal choice for anticorrosion of pneumatic valve.







fluorine-butterfly explosion-proof pneumatic ball valve actuators have double-acting and single acting two forms, double-acting pneumatic valve open for ventilation, ventilation to shut down, when need to close the lost air keep in situ; The single acting has the function of automatic reset pneumatic valve open or close the ventilation ( Can be set) , losing under the condition of gas source is automatically shut down, Or open) , its principle is to rely on automatic reset spring, commonly used in dangerous working conditions, such as transporting combustible gas or flammable liquids, when loss of gas source and there's an emergency, pneumatic valve can automatically reset to minimize risk.
