 POSITIVE  CHOKE  VALVE

Positive  choke  valve  is  used  as  flow  control  of  wellhead  and  X-mas  tree.  All  pressure-containing  parts  are  made  of  alloy  steel  with  enough  tensile  strength  to  ensure  the  safety  and  reliability  at  rated  working  pressure.  Choke  beans  are  made  of  hard  alloys  for  good  wear  and  erosion  resistance.

Technical  parameters:
-  Pressure  rating:  2000~15000psi
-  Operating  temperature:  P  U
-  Operating  medium:  oil,  gas  and  water
-  Choke  bore  diameter:  3,  4,  5,  6,  7,  8,  9,  10,  11,  12,  13,  14,  15,  16mm

 ORIFACE CHOKE VALVE

Orifice  choke  valve  is  molded  of  two  pieces  of  special  carbon  tungsten  plates  with  excellent  ability  of  erosion  resistance,  one  of  which  rotates  to  alter  the  concentricity  between  the  upper  orifice  and  lower  orifice  of  two  plates  so  as  to  adjust  the  flow-rate  of  fluid  or  gas. 
The  valve  is  used  for  manifold  such  as  drilling,  fracture,  mud  circuit,  ground  high-pressure  gas  injection/production,  it  has  a  outstanding  feature  that  the  pressure  difference  between  inlet  and  outlet,  as  closing,  can  press  both  of  the  plates  fast  together  so  as  to  put  into  effect  of  sealing  cutting,  especially  in  the  case  that  the  pressure  suddenly  rises  or  falls,  the  pre-set  sign-rate  of  high/low  pressure  sensor  can  be  helpful  for  automatic  closing/shut  so  as  to  avoid  heavy  accident.  It  is  outstanding  advantage  that  it  has  long  working  life  and  ability  of  erosion/corrosion  resistance  in  comparing  with  other  choke  valves.
