Pneumatic butterfly valve

Pneumatic butterfly valve

    Butterfly valve body by a high pressure aluminum alloy body, deformation wear aprons, polymer composite butterfly valve. It is an ideal product for closing hopper, hopper and a powdery or granular material silo, is widely used in cement, concrete mixing station transmission steel gravity dust etc..Because of the special structure of the valve  and the use of engineering materials, it is always a very economical and efficient selection.


 

1. Pneumatic  butterfly  valve  butterfly  design  overall  dust  delicate,  more  than  80%  parts  evenly  using aluminum  alloy  materials,  light  weight.
2. The  dust  butterfly  valve  for  cylinder  design  company,  to  the  bunker,  hopper  materials  quickly  cut  or open.
3. The  cylinder  is  made  of Y  type  +O  type  ring  combined  seal  structure,  greatly  increasing  the  service life  of the cylinder.
4. The  body  consists  of two  high  pressure  die-cast  half body  composition,  half body  for  aluminum  alloy material.
5. Valve  coil  design  for  U  shape,  enhance  the  deformation  of the  sealing  ability,  with  automatic  recharge function  wear,  wear-resistant,  high  efficiency,  and  zero  leakage.
6. The  aluminium  alloy  rotating  the  butterfly  plate  and  the  valve  shaft  adopts  the  integral  casting molding, convenient installation.
7. Having  a  top  flange  and  a  removable  pipe  connection,  suitable  for  the  connection  of  a  flexible  pipe, convenient   connection and discharging.
8. Usually  installed  in  the  hopper,  hopper,  silos,  below  the  conveyor  screw  pump  or  other  types  of connections, and pneumatic conveying pipeline.
9. According  to  the  field  work,  driving  mechanism  choice  of pneumatic,  electric,  hydraulic,  gear  and other control mode.
