Plug
and Cage Trim
Large
body annulus maximizes Cv and
eliminates body erosion Plug
and Cage control choke trims
provide maximum flow capacity
and are used in Production and
Injection service.
Flow is directed through the
ports in the trim to impinge
on itself in the centre of the
flow cage. The internally guided
plug controls the opening and
rate of flow. The cage is supported
at both ends to provide a rigid
and robust trim suited to Production
and Injection applications.
The plug shuts off flow by making
contact on an internal prepared
surface at the bottom of the
flow cage.
