Valve Co. Control Chokes utilise a ported
cage type trim to provide fine and accurate
control of flow. |

Experience
coupled with testing have shown the
use of 4 diametrically opposed ports
can provide the highest wear resistance
in a 'cage' type flow trim.
The use of 4 small ports in the lower
section of the cage provides fine
control at low openings while the
4 larger ports provide capacity for
higher flows.
4 Port flow geometry provides a balanced
flow pattern which when coupled with
the enlarged body gallery of these
chokes will maximize lifetime and
return on investment. |

4x4 Control Choke
Trim |
Flow
is directed through ports in the flow
cage and accelerates into the centre
of the trim where it impinges on flow
from the opposite port.
Flow rate is adjusted by the use of
a plug moving inside the flow cage
'Plug and Cage' or by use of a sleeve
on the outside of the flow cage 'External
Sleeve'.
Plug and Cage type trims provide a
robust design with maximum flow capacity
often used in oil production and injection
service.
External sleeve type trims provide
an optimized resistance to erosion
and are often used for high erosive
service and high pressure gas production.

Plug and Cage
Trim |
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.
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.
The plug shuts off flow by making
contact on an internal prepared surface
at the bottom of the flow cage.

External Sleeve
Trim |
Flow
is directed through the ports in the
trim to impinge on itself in the centre
of the flow cage. The externally guided
flow sleeve controls the opening and
rate of flow.
External Sleeve and Cage control choke
trims provide maximum wear resistance
and are used in high erosion production
and high pressure service.
Large body annulus maximizes Cv and
eliminates body erosion.
The flow sleeve shuts off flow by
making contact on a seat ring outside
of the flow cage, by keeping the seat
surface away from high velocity flow,
the seat integrity is maintained. |
