the API - pneumatic butterfly valve




tilting rotary control pneumatic valve

to change the butterfly plate by spherical bearing inner ring sealing surface in pneumatic valve seat sealing surface contact position, eccentric bearing reaction to the surface of the axis of symmetry, so that it can relatively outside on the surface of the cylindrical symmetry axis rotation, the large diameter butterfly pneumatic valve has the characteristics of compact structure. End connection: flange


GB/T - reference
API -




spherical sealing butterfly pneumatic valve

symmetric rubber bushing butterfly the deformation characteristics of the pneumatic valve is spherical seal. In order to reduce the sealing contact area and improve the sealing, the butterfly plate around dig hollow parts. End connection: wafer

GB/T -
API -




metal sealing butterfly pneumatic valve

metal pneumatic valve seat sealing surface with a metal plate glass, the protruding end contact with butterfly plate, elastic effect. There will be the device of the pneumatic valve is closed, because of the pressure difference, sealing ring in the axial and radial elastic deformation, has excellent liquid sealing, long service life, easy to manufacture. End connection: wafer

JB/T -




fluorine plastic lined butterfly pneumatic valve

pneumatic valve body by fluorine plastic lining, in order to make the elastic on sealing surface, improve the sealing, lining in the outer layer has a second synthetic resin and fluorine rubber. This pneumatic valve can be applied on an applicable to strong corrosive medium in the pipeline. End connection: wafer

GB/T -
API -




eccentric metal sealing butterfly pneumatic valve

eccentric butterfly plate installed in the pneumatic valve stem, its edge is spherical, and to match the elastic metal sealing ring, sealing ring ring, its center deviation from the center line of the pneumatic valve, and adjusting the cricket face the centerline of the purpose of sealing

JB/T -




the pneumatic butterfly valve used for cryogenic liquid

this is a two-way role the pneumatic butterfly valve, sealing ring have V groove bottom, sealing ring opening behind, in order to put compensation coil spring. In general and low temperature conditions, can form a two-way axial seal and clamping device, and the butterfly plate form a radial seal






soft sealing double eccentric butterfly pneumatic valve

with double eccentric structure, reduce friction sealing ring, prolong the service life of pneumatic valves
other sealing principle and structural characteristics with the serial number
