General Description
The plug and cage choke uses a 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.

Design Features
The plug and cage design is highly optimized and incorporates the largest-possible flow area, making it ideal for high-capacity applications. Plug and cage chokes also are constructed with a solid tungsten carbide plug tip and inner cage for extended resistance to erosion.
·Pressure-balanced ports reduce stem loads and actuator output requirements.
·Large annul area reduces the risk of body and trim erosion caused by high velocities.
·Manual or actuated operation are available. Customized trim components in order to adapt different flow characteristics also are available.
