As the characteristics of the pneumatic valve is introduced

( l) Simple structure than the brake pneumatic valve, manufacture and maintenance are convenient.
( ） Sealing surface is not easy to wear and abrasion, good sealing, opening and closing the pneumatic valve with pneumatic valve seal and no relative sliding between, so wear and scratches are not serious, good sealing performance, long service life.
( ） When opening and closing, small pneumatic valve stroke, and therefore by the pneumatic valve height is smaller than brake pneumatic valve, but the length is longer than pneumatic valve gate structure.
( ）
( ） Large power, low power consumption.
( ） Nominal pressure resin N clusters MP medium flow direction. , generally USES the downstream, medium from BuLiu pneumatic disc under direction; Nominal pressure resin) MP。 Using counter-current, 2, medium from pneumatic disc L direction I. 'flow, in order to increase the sealing performance. When using, cut than the pneumatic valve medium can only single direction, can't change the direction of flow.
( ） When fully open pneumatic disc is often affected by erosion.
