Explosion-proof electric pneumatic valve flange sealing butterfly images

Explosion-proof electric pneumatic valve flange sealing butterfly generally use nitrile butadiene rubber, fluorine rubber, edible rubber etc as sealing material, in any case all has good sealing performance, are often used to disclosure requirements strictly and corrosive medium in the pipeline. And use explosion-proof electric actuators, protection grade is in commonly IP65. 67. 68, explosion-proof grade for Exd Ⅱ BT4 or CT4 explosion-proof marks, able to adapt to the operation condition of the flammable and explosive occasions! Widely used in food, environmental protection, light industry, petroleum, chemical industry and teaching equipment, paper making, electric power industries in the automatic control system for industrial process.




explosion-proof electric pneumatic valve flange sealing butterfly while aging resistance, corrosion resistance, good sealing performance, long life and other characteristics, but does not apply to medium containing particles, or high temperature and high pressure, usually used in the process parameters for the temperature in the - Between 40 ℃ ~ 150 ℃, and the pressure in & le; 2. The pipe within 0 mpa. If use for more than this parameter, you should choose seal structure for the metal material of electric pneumatic valve hard seal butterfly!
