Plug And Cage Choke Valve

Plug And Cage Control
Choke Valve

The plug and cage control choke uses the plug as the controlling element and throttles the flow on the internal diameter of the ported cage. The ports in the cage are sized and arranged to give the most appropriate combination of control and flow capacity for each application.

Applications
  • Available in various sizes ranging from CC15 to CC80 choke models
  • Tungsten carbide plug tip in conjunction with solid tungsten carbide cage optimizes wear resistance in erosive conditions
  • Metal body-to-bonnet gasket for absolute pressure containment

MULTIPLE ORIFICE

Multiple Orifice Choke Valve

Low Cost, Compact Design,
For Use with SAV Angle
Seat Valve

Orifice choke valve adopts a rotating fork, generally speaking, orifice choke valve only need 90° or 180° rotating direction, in this way, switch can be regulated. Rotating fork possesses lock position at both ends, which greatly improve the stiffness of rotating fork and make it move stably, and in this way.

Applications
  • Wellhead
  • Manifold
  • Separator Letdown
  • Heater Bypass
  • Waterflood
  • CO2
