Needle & Seat Type Choke Valve

  • Mainly used on wellhead Christmas trees
  • Valve plug and choke bean adopt high abrasion resistance hard alloy to endure long hours erosion and corrosion.
  • Open indicator and safe lock relief device
  • Available with pressure relief valve.
  • JFK needle type choke valve and JFG positive choke valve are interchangeable in body of the same size

Orifice Type Choke Valve

  • Mainly applicable to drilling, fracturing, slurry circulation and land high pressure gas injection/production. During shutoff, the pressure differential between entry and outlet pushes two orifices tightly against each other for seal and cutoff
  • In case of abrupt pressure change, the valve can automatically shut off by pre-set high and low pressure sensor.
  • Equipped with upper and lower orifices. The orifice open extent can control flow by turning the handwheel. Orifice adopts hard alloy to increase erosion and corrosion resistance. The valve can be used as a shutdown valve.
  • Allowing a smooth choke flow curve
  • Inner bore of the outlet features extended wear bushing to extend service life.
  • Tubing head adapter on the outlet can be replaced depending on different pressure conditions.
  • Stem seal is made of special materials to deliver good chemical stability and corrosion resistance to medium.

Plug & Cage Type Choke Valve

  • The cage type design enables fluid flowing along the cage centerline, avoiding erosion and corrosion to choke components and reducing noise.
  • Choke components adopt hard alloy tungsten carbide to deliver wide choking area, low noise and excellent resistance to erosion.
  • Metal-to-metal seal, easy maintenance
  • Annular space helps to reduce corrosion to body.
  • Low open/close torque, stable operation
  • Easy flow adjustment, allowing stable flow curve.
  • Stem seal is made of special materials to deliver good chemical stability and corrosion resistance to medium.
  • Valve plug and choke bean adopt high abrasion resistance hard alloy to endure long hours erosion and corrosion.
