Product Description

Product Description

The valve  system to  absorb,digest foreign  technology,using three-dimensional  eccentric  multi-level  metal  seal  structure,applicable  to  medium  temperature≤550ºC metallurgy,electric  power, petrochemical,as well as to the drainage pipe for regulating fuid flow and cut off the best device.

Feature

1.butterfly plate seal for the hard and soft layering pieces of metal with a metal seal and flexible seal the dual advantage of both low and high temperature cases,both with excellent sealing perfomance.
2.using  three-dimensionaleccentric  structure,valve  seat  and  butter-ly  plate  almost  no  friction,with  the  more  closed  more  tight  sealing  function.
3.valve  sealing  surface,using  welding  stainless  steel,coball-based  alloy.sealing  surface  wear  resistance  and   long  service   life.
4.The  structure  is  unique,the  operation  nimble,reduces  effort,con-veniently.the  medium  pressure  high,the  low  influence,the  sealing  property  not  to   be  unreliable,the  service  life  is  long.The  usual  double  eccentnic  butterfly  valve,as  b(deviate  from  the  pipe  center)and  a  (deviate  from  the  sealing  surface  of  the  centeriine)as  shown  in  the  ai  of  reducing  valve  seat  and  seal  between  the friction  of  appro-ximately  15  °travel.HPV  adds  a  unique  eccentric  anglep,slope  of  the  cone  not  only  overcome  the  valve  open  and  close  the  sea  and  the  seat  all  contacts  betweenthe  frriction, thereby  increasing the  service  life,but  also through  changes  in torque  canbe  applied arbitrarily to adjust their seal over  pressure,so that  more  reliable  seal  and  never  pass  phenomenon  occurs.
