CAMERON DR-Type Gate & Seat
Drilling Chokes
• Available in 2” and 3” nominal sizes
(DR20 and DR30 models).
• Working pressures: 10,000 psi to 15,000 psi
models as standard. High pressure models also
available, up to 25,000 psi.
Cameron’s drilling choke product range consists of two main choke types: the CAMERON® DR gate &
seat type and the WILLIS® Multiple Orifice Valve (MOV) rotating disc type.
These chokes control the pressure in the well bore during drilling, circulate out any kicks of gas
encountered during drilling, and prevent loss of well control by maintaining a satisfactory column
of drilling mud. With several options and configurations, Cameron’s drilling chokes offer proven
performance within diverse drilling applications on a global scale.
DRILLING CHOKES ////////////////////////

Features and Benefits:
• Design includes reversible gate & seat components, allowing up to twice
the service life of a normal non-reversible drilling choke trim.
• Gate & seat trim design is highly blockage resistant, with potential to
perform a flushing stroke in the event of large solid material to flush
through any debris and restore normal operation.
• Controlling components (gate & seat) are made from solid tungsten
carbide for maximum durability.
• Available in manual and hydraulically actuated configurations.
• Actuated configuration includes a pneumatic pressure-type position
indicator as standard. A digital position sensor option is also available.
• DR20 provides a 1.75” orifice diameter.
• DR30 provides a 3.00” orifice diameter.
Cameron’s WILLIS MOV-Type
Rotating Disc Drilling Chokes
As the original patented rotating
disc-type choke, the WILLIS MOV
became part of Cameron’s product
range in 1987, having been
supplied to drilling, production,
and various other applications since
the 1950s. Building upon extensive field
experience, Cameron offers the M3D choke for
drilling services.
• Available in 3” nominal size (M3D).
• Working pressures: 10,000 psi and
15,000 psi as standard.
Drilling Choke Control Panels
Cameron also supplies a range of drilling choke
control panels to suit various choke types and
configurations. The control panels are comprised of
a rugged stainless steel enclosure to withstand harsh
environments. They require no calibration and little
to no maintenance over an extended service life.

Features and Benefits:
• MOV disc-type trim design features a 180-degree rotation
from open to close.
• Half-moon (or D-shaped) flow area for drilling applications
gives accurate control.
• Disc components are made from solid tungsten carbide for
maximum durability and may also be rotated in the reverse
direction, giving what amounts to a new set of controlling
faces, which extends the service life.
• Highly resistant to blockage by allowing large solids
to pass through.
• Precise diamond-lapped discs are within two light bands of
flatness, ensuring reliable shut-off performance.
• Differential pressure across the trim provides a strong
retention force between the two discs, ensuring accurate
flow rate control and reducing the risk of trim vibration.
• Wiping action keeps disc surfaces clean, reducing trim wear
and deterioration.
• The choke outlet spool has a replaceable outlet wear sleeve.
• Available in hydraulically and manually operated
configurations.
• Actuated configuration with a pneumatic

FLS Valve Trim Chart
FLS-R Gate Valve
Cameron’s FLS-R gate valve was designed for use as a manual
valve in large-bore applications with pressure ratings up to 30,000
psi. This valve incorporates a lower balancing stem and unique
ball-screw mechanism for ease of operation in the field. The FLS-R
valve is value-engineered for reliability, low torque, and ease of
operation and service. The FLS-R valve has many of the same
features as the FLS version including the gate and seat design.
Features and Benefits:
• Bi-directional design provides flow direction
versatility and increased service life.
• Includes positive metal-to-metal sealing
(gate-to-seat and seat-to-body).
• Simple, reliable gate and seat designs promote
ease of field service and minimal spare parts
inventory.
• Two spring-loaded, pressure-energized, non-
elastomeric lip seals between each seat and
body assist in low-pressure sealing and protect
against intrusion of particle contaminants into
the body cavity and seal areas.
• Lower stem balances pressure thrust on upper
stem to reduce operating torque, prevents
body cavity pressure buildup during operation,
and provides position indication.
• Spring-loaded, pressure-energized, non-
elastomeric stem seal covers a wide range of
pressures, temperatures, and fluids.
• Features pressure-energized metal-to-metal
bonnet seal.
• Either stem can be backseated to allow stem
seal replacement with valve under pressure.
• Grease injection fittings are located on
the downstream side of the stem and the
balancing stem back seat for safety.

FC Style Gate Valve vs. FLS/FLS-R Gate Valve
With a commitment to innovation and best-in-class products, Cameron’s FLS and FLS-R gate valves improve upon the older FC-style
design with a more efficient design that reduces leak paths. Because of the separate body brushing and seat ring seals, the FC-style
gate valve design has more sealing surfaces than the FLS and FLS-R gate valves, which means more potential leak paths. The newer FLS
and FLS-R one-piece seat design, with fewer parts and fewer sealing surfaces, increases service life and decreases the number of leak
paths. Their dual spring-loaded, pressure energized, non-elastomeric lip-seals between the body and seat protect from damage and
assist in sealing to offer reliable service.
