VALVE

  High performance butterfly valves ： Generally refers to  double eccentric butterfly valve  and  triple eccentric butterfly valve ,due to their excellent working performance and high sealing ability (compared with concentric butterfly valve) are widely used in petrochemical,power plants,metallurgy,civil heating fields.Eccentric butterfly valves have the good working performacne to meeting sever and strict requirements in many different industries.Today, we are going to introduce the application of eccentric butterfly valve in air separation for making oxygen,hydrogen,CO etc. At present,the mature air separation system is PSA(Pressure Swing Adsorption),it need certain number of programmed valves (valve parts usually double or triple eccentric butterfly valve) in its pipeline system to control and adjust the medium. FEIDA  double (and tripple) eccentric butterfly valve are widely used in this kind of PSA system due to the valves' excellent features: 1-Long s...
